Tire Pressures

[CAC Windsport]

I have a 2008 Windsport 36R, and I know there are not many of these around, but I am looking for information on what tire pressures were on these vehicles when they came from the manufacturer or what others are running in their tires?

I have 235/80R 22.5in Michelins.

I understand the need to weigh each corner of my coach to understand what pressures are best but unfortunately there are no weigh stations near me and none closer than a day or two drive that can weigh each wheel.

So until I get to one, I am in need of info on what most are using for tire pressure or what the manufacturer used when new?

Or if anyone knows the Gross Axle Weight for each axle?

-I dont carry much water, I always empty the tanks.
-I also tow a Jeep Compass, 4200 pounds
-I have been running 90 psi but worry it may not be enough

Thanks for your help

Do a Vin search and you should be able to get the axle weight specs based on the chassis info.

There is a yellow sticker in your RV with the recommended tire sizes and inflations for your coach from the factory at GVWR. Most are to the left of the driver under the side window.

Stickers May no longer exist on a 13 year old rig.

Exactly, there doesn't appear to be a sticker on it with that info

The tires should have a "max load inflation" imprinted on them, personally I'd use that pressure.
There's also a "max load rating" imprinted on them, just realize that for every pound you deflate below that recommended inflation you are also decreasing that load rating.
You're running 22.5" commercial grade tires so apparently you have a heavy motorhome, I'd recommend running the max inflation imprinted on the tire, it may make the ride a bit harsh, after all it's not a luxury car, but will help with tire wear & temperatures.
IMHO weighing each tire location & having multiple inflation's on each corner is a waste of time, then add/remove weight to/from this corner or that one & having to readjust inflation's, what a PITA, inflate all the same & live with it.

There should be a label with the max. You can adjust from there. If there is a truck stop try there. Most have CAT scales $12. Michelin web site has pressure chart for their tires. Out Aria is 10,000 front and 19,500 rear. according to Michelin that is 85 psi front 90psi back. We are close enough left vs right.

Post 7 - no labels

Where would they go? They are required to be permanently affixed to vehicles since 2005. They may not be yellow - they may just be black print on a white background.

They are required to be there when the vehicle is new but there are no laws, that I am aware of, that state the owner cannot remove or otherwise destroy them. The only thing that must remain in place is the permanently. affixed VIN plate. Some owners do not like the big ugly stickers that were placed on their walls. Just like they don't want dealer badging or stickers that say fresh water, low point drains etc...

Also, the stickers will come loose and fall off due to environmental conditions such as high humidity and heat.

BTW, my tire pressures are not on the yellow sticker. My tire pressures and axle weights are on the white incomplete vehicle label which is on my driver's side door jam. I went back to my ics and the same held true for the Challenger, no tire pressures oil the yellow label.

Stickers will often fade to the point where they can no longer be read...

You don't necessarily have your tires at different pressures each corner, you generally inflate both sides the same and to the higher load requirement
Running tires over inflated can be problematic too, which is why you don't just run a max inflation

NEVER use the pressure printed in the tire That us the maximum, never to exceed cold pressure for the TIRE, not the coach. Use the RV label, if present, for starters. The best way is to weigh each axle of your coach at a truck stop scale. Then go to the tire manufacturer's website and find the tire pressure tables. They will tell you the correct pressure.

I recently emptied out and sold our 2002 Thor Windsport 32R and, much to my surprise, found the tire info sticker glued to the wall inside the bedroom closet. Can't explain why I never noticed it there. Or why they put it there.

I have the exact same MH. I have the weight sticker your looking for. I can take a picture of it and post it tomorrow, unless you find one or your answer before then. Let me know.
