I have used the Pressure Pro system for 3 years. I believe I was 'one of the first' to try the product. I used it on my Eagle and can only offer praise. I have never had any problems with the sensors or the receiver. After owning the system for a couple of years, I did purchase the repeater (It was not available when I originally purchased the system).

I am in the process of installing the system on my Prevost. It is very interesting to see the differences in tire pressures temperature will make. Also, the sun shinning on one side of the vehicle will also show a difference. Before I leave for a drive in the morning, I scan through the tires to see what the pressures are. With experience, you will see that checking the tires early in the A.M., when it is cold, will yield a different pressure than when it is warm outside.

The only warning I can offer is, beware of the early morning wake up alarm! The unit is pre programed to alarm +/- 12.5% of the pressure of the tire when the sensor is installed. For example, if you install the sensors with a static pressure of 110 PSI in Texas on a sunny afternoon. Then travel to Colorado and camp in the high country with typical mornings in the summer dipping into the high 30's or low 40's, the low pressure alarm will sound. I toad tires were the worst offender of the early morning alarms. The variation of pressure from the change in ambient temperature was vary informative. To eliminate the false alarms, I would simply unplug the receiver at night before we went to sleep.

I would definitely recommend the unit. The 'peace of mind' factor is worth it.

I monitored the rig and toad on a 40 foot Eagle (10 sensors, I need to get 2 more). The repeater eliminated any false alarms from the rear that I would get on very rare occasions. Without the repeater, when I stopped the rig, I would get a 'no signal' alarm on the left rear inside dual. As soon as I started to roll, the monitor would start detecting the sensor. The repeater solved that issue.

A good system!

The #2 website is www.smartire.com (only one T in the name). I have used this system for several years. I had it on two plastic coaches and when I bought my Prevost it was not on it. I was never fully at ease driving, not knowing what my tires were doing even though I checked them on every trip, stop, etc.

The SmarTire systems monitors pressure and also temperature. So if a bearing or other wheel/drive component is failing the temp will be monitored and you will be alerted prior to a major failure.

The sensor is attached to the wheel by a large hose clamp, thus the tires have to be dismounted, and the signal is received by a dash mounted monitor. The problem alert is a sound and a red flashing light on the monitor.

I believe this system is more expensive than the valve stem mounted types but I feel it is worth the extra $$ for the value received. I have used it for the past 8 years and would not be without it.

I have the tiresafeguard by HCI, The system works, it even told me when the valve stem cracked on both my inner duals. Since they both broke within 50 miles of each other I knew it had to be something new. I had just installed them prior to the trip to Aguanga,CA rally. We have all read the threads about inner wheel stem extension, so when you put something on the end like a monitoring device the likelihood of a stem failure increases. the HCI people are very friendly and helpful. If you contact Tim in thier sales dept you can get a POGGER discount. Just make sure you support that long extension. I will work on a extension like I have seen on some trucks using flexible extension attached to the center of the hubs.

One of the things that surprised me was the temperature and pressure changes will driving. Even to the point where you can tell what side the sun is on by the difference in temperatures.

Picked up a Pressure Pro system at the SEA rally in Fl a couple weeks ago. Needed to keep the other half fealing safer and more at ease after haveing a left front blowout last Aug. Have been really pleased with the system, it's great
knowing what the rubber is doing at all times. Did also get the repeater
was told with the length of our coaches and thr amount of steel it was a good choise. Ditto the warning of the early morning alarm, just unplug it overnight. I think it would be a good choise!

I don't have a tire pressure sensor system, but if I were to get one I would use the type that has the band holding the sensor inside the tire.

If a system with an external sensor was to be used however, I would steal a page from Joe C's play book and add a dedicated valve stem (a straight short stem) 180 degrees opposed to the existing stem exclusively for the sensor. In that case there would not be any risk of fatigue failure of the valve stem, and the sensor, once installed and leak free would not have to be removed for tire filling.

02-21-2008, 08:51 AM

You guys are great. So here is the analysis so far. Jon and Denny feel that Smartire is the best choice, Jon feels safer having the wheel band over the tire valve stem system, fatigue etc.

Bill, Hector and Jack are fans of Pressure Pro., which is a tire valve stem mounted system.

Greg purchased Tire safe Guard. Mentioned an issue with valve stem cracking. Question, what role did the system play in this, detected it, but did it exacerbate the problem??

Lloyd has a new solution, Mobile Awareness.

Question: How much do these systems cost? How difficult is it to install the Smartire system? Is there a way to install the valve stem system and insure its extra length and weight will not crack the stem.

I would prefer the easy route, as long as it improves the safety aspect, and does not create a new risk.

Thanks,

Bruce

Jon Wehrenberg

02-21-2008, 09:52 AM

Bruce, The band type does not create or add any risk due to its design.

Any type with an external sensor on a valve stem has some potential risk, but with Joe's approach using a second valve stem he has minimized the potential.

In order for it to work, a sensor opens the Schrader valve so it can read the internal tire pressure. As a result you are totally dependent on the seal between the sensor and the valve stem. A secondary risk is the weight of some sensors has the potential to create a fatigue failure of the stem if the stem is long and has a bend.

But by putting in a second straight stem (or a bent one as long as it is very short) that risk is minimized. The sensor never needs to be disturbed to add air, and the valve stem for adding air has two seals, the Schrader valve, and the valve stem cap.

The question is always of relative risk versus cost versus ease of use or features.

WHAT GIVES????????????? Jack mentions he is going to experiment with nitrogen and not even a single slam;) Peter must be sleeping and Jon wore out.

Looks like pressure pro has upgraded their display panel it is different from what we have.

It is 700 bucks if you want enough sensors to do the toad.

The sensors have a shelf life of 5 years they have a internal battery that wears out. Sensors are 50 bucks each. I had one go bad this winter after 4 years but it is often subjected to this cold Chicago winter and I believe that did not help.

Jack how hard did you have to tighten the sensors to get them to seal. Ours were not easily tightened to get them tight enough not to leak. Have they addressed this issue. Other than that I love them, very cool:cool:

Hector do a search of old posts on this topic you will enjoy my comments. The pressure on the inside duel port side will rise when the generator is running cause the exhaust pipe runs close to it!

Jon Wehrenberg

02-21-2008, 01:56 PM

No need for me to comment about nitrogen. It does nothing but make someone money. And I won the discussion before anyway.

I am looking at the possibility of using Helium to reduce the weight of the coach. That and maybe adding calcium to the tires like they do with tractors to keep it from tipping over when I take a curve at 62.5 mph.

02-21-2008, 01:58 PM

I think I will move on the Pressure Pro as well, based on the total package. Joe do you know a good source. Also what is the deal with the Extensions, cracking etc. How did you manage this? How tight is tight enough and what are you tightening it with?

Didn't you folks discuss Nitrogen before? Also what about the Michelin X One XRV, does this really save fuel? maybe we should open a new thread on this.

Joe Cannarozzi

02-21-2008, 02:43 PM

I believe you have to go to the manufacturer for it.

Extensions are no good, try to avoid them period.

How tight is tight enough? Enough so that they are seated and do not leak(the soapy water test).

I'm sure Jack will respond to my question in my previous post in this thread. I would enjoy a response on this issue from all others who have pressure pro.

The directions specify not to use anything other than your hand to tighten or damage may result. That any sensors returned with evidence that something was used to tighten them like plyer marks or such would void warranty and that is exactly what I HAD to do to get a couple of them tight enough to seal:eek:

Do a search on the nitrogen question there is a pretty lengthy thread on it and it has cost me a meal and a certian amount of respect too.

The sensors are VERY LITE and I understand the additional stresses to the stem due to centrifugal force but think that they would have shown something bad on ours by now, we are going on 5 years and no issues there.

I also do not care for the idea that you have to remove them to air the tire up but if they have resolved the tightening issue we encountered then it would really not matter.

We have been using the Pressure Pro for a couple of years now and the system has done a great job for us. Finger tight seems to work very well along with a soap check. Our seals are the red color and are very soft. Would surmise that seal problems could be due to nicks in the stem.

For those who are concerned about temperature sensing, Joe's comment about increased pressure due to his generator exhaust illustrates the fact that high temperature is indirectly sensed by the system. When pressure decreases or increases more than about 12% the offending wheel indicator flashes and you will experience a very noisy pressure alarm. :eek:

As to dealers, there are a number of small dealerships around the country. We purchased ours from Mike & Pat McFall (850-294-0281)who sell the Pressure Pro at numerous RV shows etc around the Southwest. I believe they winter in the Wickenburg, AZ area.

Ray Davis

02-22-2008, 02:18 PM

I have been considering getting a monitoring solution for awhile, but have been scared away from the external cap types, just due to the issues associated with a device on the end of the valve stem.

But, it seems to be from comments here that the model of choice is this external kind. So, it brings questions to me:

1. Are you not concerned with valve stem damage?

2. Do you have to remove the cap every time you air up? Is that a nuisance, especially considering they seem to need some "love" into getting them to seat leak-free?

3. What was the major reason to chose the external type, over the internal mounted sensors?

I had been considering getting the internal sensors, but I'm assuming the cost is much higher. ARe they any drawbacks other than cost? I would assume you replace batteries with each tire change? Hopefully these would go 5 years without needing a battery replacement.

Ray

Joe Cannarozzi

02-22-2008, 03:41 PM

Ray your thoughts are right on. It is cost to some extent, for us it was, and if I remember correctly the internal sensors are north of 1000 bucks, not including the toad. The Pressure-Pro is about 700 and that is including the toad.

However you will not have concerns about someone (kids, I had a couple lifted from our P/U) removing them. You can air the tire up normally without having to remove a sensor, do not have concerns about valve stem leaks and the internal ones also give a temp. that the external do not.

So it is not like you are not getting anything for the extra cash. Add the expense of mounting and dismounting tires unless of course you coordinate the purchase with new tires.

I would buy Pressure-Pro again but given some extra cash I would love to upgrade to the internal style. I'm guessing that the internal ones have a battery life issue too, I do not see how they would function without one.

Jon Wehrenberg

02-22-2008, 04:30 PM

This is just an observation, but it is not a big deal in my opinion to install the internal band type.

I say that because apart from the labor to remove and reinstall the wheel on the coach, the time to pull one side of the tire from the rim is less than 2 minutes. At that point the entire inside of the rim is exposed to install the band, and another two minutes will reinstall the unmounted side of the tire. The tire should air up because it was already spread and aired up, unlike when it was purchased, collapsed from sitting in a stack.

I think the 4 hours I would guess it would take to do the whole job would be time and money well spent.

Ray Davis

02-22-2008, 04:34 PM

I was just looking at the various options on the web, and there appears to be two Pressure Pro systems. One from Doran, and another by L&S. The L&S site in fact mentions that Doran is no longer selling the original. http://www.tirepressuremonitor.com/

The units look virtually identical on the websites. Anyone know about the differences?

Ray

jack14r

02-22-2008, 07:45 PM

The difference is the L&S has their logo on the display and they do not discount.

Ray Davis

02-22-2008, 08:18 PM

So, interestingly enough I spent about an hour on the phone with the main guy at L&S today. He was extremely helpful. He indicated that Doran was no longer an authorized distributor (since October?) for PressurePro. Pressure Pro is actually manufactured by Advantage (www.advantagepressurepro.com) and L&S is a distributor. Evidently Doran was a distributor until just recently, but is perhaps getting rid of old inventory? That was his take on it. He also indicated that Doran will be coming out with their own product. He said it was unfortunate, but I guess many people believe Doran is the maker of Pressure Pro, which isn't the case.

Anyway, on the good side, he brought up a few points that I hadn't considered, when I was thinking of using an internal brand monitor:

* flexibility - You can easily take monitors off one toad, and put on another, or like pulling a boat trailer, where you want to do it rarely, not enough to justify purchasing additional sensors.

* L & S have developed a wrench with a lock nut that makes it difficult for someone without tools to steal the sensors from your tires.

* They also emphasized to not put these monitors on extenders on inner dual wheels. He seemed surprised, however, that it was something I was concerned with. Evidently many of his customers are not.

* He stressed (again for flexibility) of the ease of taking the monitor out of the bus, and carrying in the toad (for example) on a day trip. Evidently it has a feature of being able to select 3 modes. One is both main vehicle and toad, main-only, or toad-only.

After talking with the guy, I'll admit I'm less inclined to purchase the in-wheel system, just because this sounds so easy. Assuming the caps don't leak, this alleviates the need of checking tire pressure at every stop.

In basic checking it appears that a Pressure Pro type of system runs roughly 50-60% of the cost of an in-tire system. That doesn't include installation. FYI, I think I read on Camping Worlds website that they will install for $533! Yikes.

Ray

Jon Wehrenberg

02-22-2008, 08:37 PM

If he does not want extenders on the inner dual wheels (which I agree with regardless of whether you use a tire pressure sensor or not) how exactly do you remove the sensor to fill the tire with air when needed?

Just as a personal observation, I will not move the coach from the garage without checking pressures. As a result I have come to recognize that each tire has its own characteristics. If the temperatures have risen since my last trip, my tires are usually either right on, or slightly higher in pressure than my set points. If the temps go the other way the reverse is true. An extended period of time between trips requires my tires to need anywhere from one pound to three pounds of air. By extended period of time I am meaning 3 months or more.

The single biggest improvement in retaining tire pressures has been the use of the sealing valve stem caps that I can fill through without removing them. The fact that my tires are "double sealed" has made a huge difference.

My single biggest source of leaks after the schrader valves was the seal between the valve stem and the wheel itself, and that often required me to retighten the nut inside the wheel.

Where I am going with this is if I were to get sensors, the external ones would cause me to lose my double seal, and ease of filling. I would rather payt the big bucks for the internal, unless Ray has the answer to how to fill the inner dual without extenders since the use of tools on the sensor is forbidden.

Ray Davis

02-22-2008, 08:47 PM

No magic answer on that one. Other than you don't have to "check" the air yourself, by powering up the system, you'll get a readout of the air pressure from the Pressure Pro system.

I did specifically ask about how to get the monitor on an inner dually, and he suggested a couple of things, none which sound perfect ...

1. If you can get your can to reach in between the tires.
2. He mentioned you could take a 1" socket, and the monitor would fit perfectly in the socket, and could be screwed in/out using an extender. Now, the monitor looks round to me, so I'm not sure exactly what grabs it.

I would venture to say the best way is as you and Joe have suggested the dual filler approach. But, I guess I have to ask, does that mean you have to do something to the wheel to get a mounting hole for a second valve? I assume you have to drill another one?

Ray

Jon Wehrenberg

02-22-2008, 08:54 PM

That's the Achilles heel with that type sensor unless you drill another hole in the inner dual wheel and add a valve stem dedicated to the sensor like Joe did.

There ain't no way you are going to go through those gyrations to put air in an inner tire if you have to reach between the tires to get at the sensor.

gmcbuffalo

02-22-2008, 10:53 PM

Again I will say that I have the TireSafetyguard system and they work fine except trying to put them on a 9" extended valve stem. This system you air up the tire thru the monitor and it measures pressure and temp with setable alarms.
GregM

Ray Davis

02-23-2008, 12:58 AM

Was it your system I saw that had a way of mounting the monitors to the lugnuts, then using a flexible hose to connect there? I think I saw a picture on a regular truck wheel, but would imagine it doesn't look as nice on the Alcoa's? But that does seem to do two things (1) let you fill without removing and get a second cap again and (2) holds it firmly in place?

Joe Cannarozzi

02-23-2008, 07:44 AM

No Ray, Gregs are the sensors that look similar to Pressure-pro accept they incorporated a filler valve into them so you can air them up in place.

I think I remember you commenting in the previous thread where a picture was posted of them that you were concerned about their size and weight.

This particular system seems to be a good compromise between the cost, convenience, and features of the accessory.

gmcbuffalo

If you remember at the Aguanga rally I was the one with the broken extensions and had to have road service replace the valve stems. Of course the extensions didn't break the valve stem themselves did. I am going to set my duals up with the flexible stainless extensons and have the monitors mounted to the center chrome cap, much like the truck you saw.

Greg, Is TireSafetyguard the complete name of the system? I searched on the term but didn't find anything useful.

Jon Wehrenberg

02-24-2008, 09:27 PM

Unless you secure the end of the valve stem, it doesn't matter if the extension is flexible or rigid.

The rotating mass exerts a considerable force right at the bend of the tire valve stem and that constant flexing as speeds vary and the tire hits bumps is what fatigues the valve stem and causes it to fail.

FYI, when we were out at the FMCA conference last week in Pomona CA, I ran into the guys from Doran. They we showing their new product which is called Doran 360RV.

Going to the Doran site now, show only the 360RV, and I don't see (in a quick look) any evidence of the Advantage Pressure Pro that they used to sell.

It looks like from their site that a 12 wheel system (bus + toad) goes for $800.

I see this site http://trikor.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=TPM-P208C has the TireSafeGuard system with 8 sensors on sale for $430 including the cabled antenna for use with a metal (vice fiberglass) bus. Shipping is free.

Strange. I just looked at their website, and indeed a unit marked as "without tow vehicle" was priced as you indicated.

But, when you got to units marked as "with tow vehicle", prices got higher by about $50 to begin with.

And for some reason a 12 sensor system (6 wheel RV, 6 wheel tow) is less expensive than a 12 sensor system (8 whell rv, 4 wheel tow). Why would it cost more for the 8/4 vs a 6/6? Same senors, same monitor, just different configuration? And why is units marked as "with tow" about $50 more than without (for similar amount of senors)??

Ray,

Good questions to which I don't currently know the answer. If I get a chance, I will give them a call later on today. If one of these systems can "safely" extend the usage of our tires beyond the 5 year mark, it could pay for itself in one set.

The one tire that I blew out in a construction zone one time wouldn't have done any damage if I had known immediately when it happened. It was an inside drive tire, and unfortunately, it wiped out an air bag before I realized I had a problem.

Ray Davis

03-05-2008, 11:46 AM

Yes, more and more I'm inclined to purchase a set. I was going to try to save a little money by only getting the bus set, but as Jon mentioned, I think knowing the toad is OK, is just as important.

Ray

03-05-2008, 12:03 PM

I'm beginning to sense a group purchase. My guess is going direct to the manufacturer with a sizeable quantity should get distributor pricing.

Are there two systems with external sensors that could be whipsawed?

Ray Davis

03-05-2008, 02:21 PM

I am leaning to the new Doran system. http://www.doranmfg.com/rvtirepressuremonitors.htm

I downloaded the manual, and I like the programability of the unit. You set the tire pressure base in the unit, not by filling tire to "correct" amount, and then putting the sensor on. You can change that value at any time.

It has the third wire which connects to ignition so that the unit will sleep and not emit any alarms at night, but as I understand it will still receive the alarms, and notify you when you take the unit out of sleep mode, i,e turn on the key.

On the downside, it's more expensive than the smartire system (external), and doesn't allow filling via the sensor. But, I'm leaning towards putting on the external stems instead.

I'd be happy to contact the manufacturer, to see if they would be willing to do a group purchase.

Ray

03-05-2008, 02:36 PM

Spoke with Debbi Gerdes as Doran Mgf. Asked about a group discount and she referred me to one of their distributors (who happened to be the guy at the FMCA show in Pomona).

He indicated we could get a group rate if we purchased at least 5 units (all in one purchase, one credit card).

5% for 5 units
10% for 10 units

Not sure if it's worth the effort to bundle, and reship units? (although he said one credit card, he didn't say specfically ship to one location)

We have gotten to the point that some of the batteries are dying with age on our Dorian, first sensor four years old.

Because of no dough I am pulling one off the toad and will do so 3 more times as the need arises. When the fifth sensor fails I am going to switch to the Tricore set-up and for these reasons:

-Way lower purchase price
-The ability to air up through them
-Twice the advertised battery life
-Tire temps. as well as pressures

And what just might be the best feature of all. If you go back to Rays post to their home page and click on brochure there is a picture of a set of duels. On them they have an attachment that fastens the sensors to opposing studs and there is flexible extensions connecting them to the valve stem. Very Cool. The flexible extensions shown are rubber but I know there are stainless braided ones out there I've see them on semi trailers pretty frequently.

Dorian has served me well but it is time to move on. Live and learn.

I will continue to use the Dorian for the toad until the rest of the sensors die then if someone would like the monitor panel you can have it and only have to purchase sensors, for a future favor:)

Ray Davis

03-05-2008, 04:13 PM

Well, just as an FYI, I called Pete's Road Service here in CA. They are a mobile tire service, serving the trucking industry. I asked them a few questions, and I thought I would share the answers.

1. I asked him the cost to unmount all my tires, and replace the existing stems with new, non-extended versions. He indicated that would cost about $6 per stem, plus $17-$18 per wheel for labor.

2. I asked if at the time that they had the tire broken down, what it would cost to install an internal tire monitor like the SmarTire system. He didn't know, had never done it, and couldn't quote me a price. (Call two stores)

3. Asked if I wanted to drill a hole into the wheel to put a secondary valve stem on, what that would cost. They wouldn't do it. Advised against it, as potentially damaging the wheel, and inviting wheel failure.

He then offered this sage advice. Best system for tire pressure monitoring is "you and a good tire pressure guage". Go out and check it once a month, he said.

I just thought I would share that!

Joe, I too am leaning toward the Trikor because I want to be able to fill the tire without removing the sensor. I had some of the little chrome sensors that flash when the air gets low, and the only problem I had with them was they would leak sometimes when I didn't tighten them enough after removing them to fill a tire. I applied a minute amount of pipe dope to the threads and didn't have any more problems. My point being that every time you take any of the sensors off you take a chance of damaging the seals and/or causing a leak.

I have the TriKor system and I think you need the cable antanae to get good reception for the tow, so I think the extra $50 is for the cable. With all the metal in the bus you will need the cable to run down to the drive axle. I have hooked up my drive axles up like the picture in the brochure, with Camping World extensions. Steve and Tim are great people to work with.

I just contacted the parent company (http://www.tiresafeguard.com/contact_us.htm) for some bulk prices. Hopefully this will bypass the jobber. This equipment is manufactured in Japan and designed by HCI Corporation 11245 183rd Street Cerritos, CA 90703. The manager is going to email me with some pricing, perhaps in increments so 10-50 sets. I will let everyone know what they come up with ASAP.

One of the owners of this compan (http://www.tiresafeguard.com/)y, Steve Wong, finally got back to me with the information we need. The reason for the delay is that they were making some improvements so their equipment will work well with metal-sided buses like the Prevost. I will try to describe some of this because their website hasn't been updated to reflect this new equipment:

First, they have 3 sending units. All report pressure and temperature. Only 2 (One is Jon's choice) give an accurate report of the temp. That is the unit that is strapped to the inside of the wheel (http://www.tiresafeguard.com/pdf/TPM-W2%20Brochure.pdf) with a stainless steel band. The other is for the Toad only and mounts inside the wheel (http://www.tiresafeguard.com/pdf/TPM-V1%20Brochure.pdf) and has a conventional cap with a sending unit. It mounts inside the tire with a valve stem that replaces the regular valve stem. (no 2nd hole in the wheel)
The last is a flow-thru cap that attaches to the valve stem. It also reports the temp but with a wide temp swing since the sensor is outside the tire. If there is a wheel bearing issue or a hung-up brake generating heat this cap could be useful, otherwise it is mostly for the pressure.

The wireless H-Monitor, designed for motorhomes, ( I have the brochure on this if you want it but I can't find this new item on their website) will monitor up to 20 tires. It will sound a preset alarm for both the Toad and the bus.

One final piece of equipment is necessary for a Prevost, a wireless signal booster that will assure a good reading for the rear tires and the Toad. This mounts in a rear bay and uses 110V as an energy source.

The retail price of this package, 8 bus tires, 4 Toad tires, H-Monitor, and signal booster, is $890.00. They are working on a POG discount. Jim is working on them as a sponsor.

I just purchased the set with the flow-thru valve cap-sending units for the bus and the valve stem replacement unit for my Toad. They should be here this week and I will make the installation prior to our July 5th trip to Lake Shasta. Pictures will be posted along with any installation quirks.

One of the reasons I purchased the caps as opposed to the wheel strap-on sensors is the $320 for removing the tires installing the device, and rebalancing/reinstalling the wheels. I can buy the other sensors, maybe just for the front tires, when I replace my rubber. One other improvement they made for the caps is that they are secured with an Allen wrench to prevent theft. The units cost less now and are manufactured in China. Steve said they are high quality. Part of that, he said jokingly, is that he don't have a language barrier with the Chinese, since that is his country of origin.

If anyone has any questions please feel free to call.

I don't know what the price is now but I bought mine on a POGGER discount (post 5 on this thread). I have put mine on flexible extensions so the temp reading is not accurate. I did this becuase I broke both inner duals valve stems because of the weight of the monitor on the long inner duals.

So, it's now been several months since we discussed all this, and I'm wondering if any have purchased systems, or if there were any new products on the market?

A check check seems to show things haven't changed much. Smartire has a new website, but it's not complete. Checking their dealer list, there are three dealers mentioned, however it seems that Camping World no longer stocks Smartire (at least on their website), nor goes the GeneralRV seem to have any indication of being a Smartire distributor. The third one, a tire dealer did seem to have a very reasonable web presence for Smartire.

2. Is there any change with respect to TireSafeGuard and a POG discount. They seem to offer an in-tire solution (as does Smartire), and are a bit cheaper. I didn't see an option to get internal sensors for the RV and external caps for the toad, which would be a nice combination.

Since I've just sealed the deal on my new coach, I am having all tires replaced (and batteries), which gives me the easy opportunity to have internal monitors installed.

I'm still trying to decide which system to purchase, and where to purchase it. I like the looks of the new Dorian 360RV system, it's very programmable, however, it only has non-flow-thru cap type sensors.

Any thoughts along this line, anyone?

I am sure that in tire sensors work fine but when it comes time to trade it would be expensive to dismount 8+8 to install the sensors on the new coach,also when a sensor fails that tire must be dismounted to repair it.I don't know how long my pressure pro will work but I can install a new sensor in a few seconds.I think that the new Doran system looks real good,it is similar to the pressure pro.My pressure pro has performed perfectly and no leaks for over a year,I would buy this product again.

Jack,

How did you get your sensor on the inner dually? Do you have the extended dually valve stem, or ??

Ray,

I also use the Pressure Pro which is very similar to the Dorian. They have performed flawlessly for more than 2 years now. I have removed them several times for routine airups, tire changes, etc and they reseal with no problems. Battery life can be prolonged by unplugging the controller unit when the bus is not being used.

When installing or removing, one has to be careful not to overtighten. That said, I use a 1" six point socket with an extension only (no handle or ratchet) on the inner dual to obtain finger-tight torque. All other sensors are finger tightened.

Ray,Both of my coaches had a 6 inch extender with a rubber gromet from Alcoa that stabilizes the extension.I have not had a pressure pro sensor leak but I have replaced a extension.

I'm just curious....why can't these tire pressure monitors be used with Equal? I have tried to find anything in the literature on line that says its use is prohibited and can't find anything.

The reason I ask is if that is the case the true cost of a system then must include Centramatics or their equvalent, right? I'm not opposed to either because there is way too much evidence that both have done a great job. But I still struggle with external sensors and the fact that you rely on that single seal, and you have the extra weight spinning around on the valve stems.

How do you remove the inward facing sensors from the outer drive wheel?

Loosen the nut around the stem and spin the stem around to a desirable position.

Right or wrong that is the way I dealt with it.

Tire Safeguard that is what I am switching to I went into detail in post 44 of this thread. I currently have pressure pro. Jon has a decent point about acess.

This product adresses all the issues and if correctly installed will provide reliable trouble free service.

How about it Will how is yours working

I use a 180 degree extender on the outside dual,it will tighten and will not rotate,the one that I bought is made out of stainless tubing.

Ray Davis

I'm curious about different pressure values for different axles. In my previous coach, following Michelin guidelines, I ran something like 125, 110, 95 in my front, drive and tag axles.

In looking at the documentation for the TireSafeGuard unit, there is a single low pressure warning level. Given my pressures from above, my tag axle is already 30 pounds under pressure.

How is this handled?

On the Smartire unit, and I believe the new Dorian unit (360RV), I believe these are independently settable per axle, if not per wheel.

Thanks,
Ray

Ray

When you screw your sensor in any particular tire the pressure is senses is that tires baseline and if it goes down 10%n the alarm goes off. If you have 100 in the tire it goes off at 90. If your tire is inflated to 80 it goes off at 72.

They advertise twice the battery life at half the cost of pressure pro. You can air through them and I like the mounts on two opposing studs connecting the sensor to the valve stem with flexible tubing.

Jack yes there are stainless valve stems.

Jon many many truckers are safely and reliably using these flexible tubings attatched to the valve stems. Many go to a cats eye that equalizes the pressure in the duels. The flex tube is attatched half way down with a bracket and the 2 sensors attatch to opposing wheel studs with little disruption to balance.

Take the savings and get the ballance rings.

I called the TireSafeGuard guys and left a message. Steve Wong called me later this evening. He indicated that indeed pressures can be set per axle, but he indicated the manuals on the website were out-of-date, and wouldn't show that.

He promised to email me newer manuals, but as yet I haven't received them. Maybe tomorrow. I was more specifically asking about in-tire monitors, rather than the screw on. He did indicate you can mix and match however. For example, I'm thinking I would want in-tire on the bus, but screw-on for my toad.

Still haven't made a final decision yet.

Jon,

The Pressure Pro Installation Manual FAQ page includes the following statement ref the use of equal:
"CAN I USE A SEALANT OR EQUALIZER POWDER IN THE TIRE WITH PRESSUREPRO? It’s recommended to use a filtered Dill Valve if using sealants or equalizing substances. Sealant can plug up the valve core and shut off pressures in stems."
When I purchased the system and asked the question about equal, I was told not to use either equal or internal tire sealants. I would suspect the sales folks were not aware of the existence of a filtered Dill Valve. Since the sensor is the only seal, I wouldn't feel comfortable with foreign material in the tire in any event.

The sensors screw on the inward facing valve stems easily and only require finger tightening. Remember that the lighter weight wheels used with 40 footers have large lightening holes. It may be necessary to rotate the valve stems on wheels with the smaller holes.

Jon Wehrenberg

09-03-2008, 06:57 AM

Thanks. I just did a tire check and timed it and it took about a minute. But I think the real benefit is if a tire goes down while driving. I just have to think this through because since I have been using the double seal fill through caps I have had to adjust pressures by a pound or two between trips and I hate to give up that feature.

The tire filling tool I use (bright red hose) is also my pressure checker and can be used without attaching an air hose for that purpose. I use no valve stem extensions and reaching the inner drive tire valve stem is easy.

I hate to go back to a single seal and have to carry around tools to remove the caps (sensors) although I suspect that is mitigated by being able to read pressures at the dash, and only those that need to be adjusted require attention.

So, after researching (again) the various possibilities out there, I've decided to get the Smartire internal mounted system.

It was a little hard to find any real information, as it seems the only US distributor is Dickman Tires in Junction City, OR. But, I got ahold of their inhouse expert, and I'm pretty confident in what I'm getting.

This is the system:

http://www.dickmantires.com/SmarTire/gen2rv.html

and they have a new optional display that I think really looks nice.

http://www.dickmantires.com/SmarTire/smartire_display.html

Price for 12 sensor (8 + 4) is around $1399. I'm just waiting to hear back from Marathon about installation. I'm hoping they will be able to install the electronics, and their tire service to install the sensors when I re-tire the bus.

I went back and forth about internal vs external, and almost went with the new Doran 360RV (I like the programmability of it), but in the end, I want internal sensors, and I really liked the round guage display option with Smartire.

So, now to "get 'er done"
