Tire Monitor systems

[0533]

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

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

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!

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.

Hey Jon. What about Viagra!

Gary,

All that will do is give the coach a stiff ride. Lew told me that.

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.

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.

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,so far mine do not leak and I only lightly tightened them,the rubber seal inside is pinkish red.Bruce try Doran MFG,their phone number is in one of my previous post on this subject.

Thanks Jack. I'll give them a call.
