Tire Pressure

[stans02]

I have new Mitchlin tires on my 26 ft Jayco. The tires say, dules should be 70 psi. There is a sticker by the gas filler that says, inflate rears to 80 psi. Who should I believe? Stan

The tires should be E class tires and the sidewall should have a maximum "cold" inflation number shown on the sidewall. Inside the drivers side door, on the jam you will find a sticker from Jayco that tells you the recommended tire inflation values "cold".

On my 31FS it calls for 80 rear and 76 front.

As long as the max cold inflation pressure is 80 stamped on the tire and not any lower, I would inflate to the door jam pressures. (80 cold)

Check and post exactly which Michilin tires you have, I am sure there are people here that know way more than me.

The best way to do it is go to the Michelin site and find their pressure recommendations. Then go weigh your rig.

Whatever tires you have, always go by the max pressure molded into the sidewall, regardless of what the stickers say. Stickers do not always reflect the correct pressure for the tires actually on the vehicle. Same for the load range, also molded into the sidewall. In my experience, it has always been best to get the rig weighed (again factory specs are not always correct due to accessories, etc), determine the load range tire that will easily support the actual loaded weight, and then inflate to the max cold pressure on the tire. You should then have no problems, unless the tire is defective. JMHO
