Will let you know what happens,

Can anyone read the chart for a 235/80R22.5 and let me know if this is a misprint. It can't be right. I'm looking at single use for the steer and tag.

This is on the Michelin web site. I was printing it for the Rally and don't think it's right.

OK, I tracked my slow leak down to the seal on my pressure pro tire sensor. (Certainly a negative of the pressure pro unit!) Replaced the seal, easy enough, and no problems. Soapy water did the deed.

In other news, I weighed my bus. I was intimidated by the scale lady, so wasn't able to get all three axles on three different scales (now I see how I could have though). The results:

Total weight, 45,780
Front, 14,529
Rear two axles, 31,260

Ummm, so what does this mean. Am I doing OK? Seems heavy in front, but then again, my generator is right behind my drivers side, front wheels.

I was only about half full on water when I weighed in and was empty on black and grey water.

I'm running with 125psi in front, 120 in drive, and 100 in tag, ONLY because that is what Marathon did when I got serviced there 5 months ago.

Any opinions?

Thanks,

Adam

Adam,

Download this: http://www.michelinrvtires.com/miche...e-material.jsp. It will tell you everything you ever wanted to know about weights and loads on your tires. Happy reading!

Adam,

The weight up front is good. YOu are allowed 9000 lbs on a 315/80 tire. Given that your front axle weight is about 7250, the Michelin Tire pressure (page 29 of the Michelin RV Brochure listed in the link above), indicates that your fronts should be no less than 105 pounds. It seems like you don't need to run all the way to 125. You could probably bring it safely down to 110. If you get above an an axle weight of 15.8k, you'd need to go up to the next level.

As for your rears, it's hard to say, since you didn't get an independent balance. Rarely does the drive axle or tags need more than the fronts, so you are probably OK to run something like 110, 105, 100.

It won't hurt to have it drive and tag at 110, 100 as you have now, but you may not need quite that much.

If possible, try to get another weight with just your rears on different scales, or if you are out at an RV park, sometimes they have local people who will come and weigh your coach right there in the spot.

The good news is that it's better to be a bit over inflated, rather than under inflated. It will basically make for a stiffer, perhaps more unconfortable right on your front tires.

Ever see those flatbed trailers with spread axles? Well they can legally carry 20000 pounds on each axle and often if loaded are right there at 40000 on the trlr cause usually the truck rides the best that way. There are 2 common tire sizes for such, 11-22.5 or 12-24.5 both sizes at a lesser weight rating than what we have on our buses. 999 out of 1000 you will see run 100lbs air pressure.

Most here have either bran new or real close to bran new and pull them at the first sign of cracking.

I would love to be at a truck stop scale to see the reaction of onlookers when a motorhome owner pulls in to weigh the drive axle one side at a time. Good Grief. What of the air bags if one side of the drives is say 1000lbs more than the other, will that cause sleepless nights.

100lbs all the way around folks 110/115 max on the steers for those heavier front ends.

How many here have 8 different pressures in 8 different tires? Fess up you know who you are.

What would be the biggest difference from one side to the other that anyone could confirm?

Joe you old gear jammer, I have to disagree....

I bought a 2004 CC Allure, 40' with tag axle. (ya I know, this is before I became Prevost smart). Out of the box, with the factory weight ticket in the paperwork, it was 1,100 lbs heavier on one drive side vs the other. Had I not read the paperwork and followed up with my own weighing of each side at the QT Truckstop in Adairsville, GA, I may have seriously exceeding the axle ratings by overloading the heavy side.

Since then, I weigh everything side to side, just to get a reasonable balance of all the components.
