Had tires rotated today

[3_dog_nights]

Steer tires had some cupping going on, had an alignment last week and had tires rotated from front to back left. Noticed when I got home they had inflated to 110#. Max pressure from mfg. (Michelin) Won't this cause the center to crown and wear faster? not to mention as they heat up they will increase pressure. What pressure do you guys run?

Its common for tire shops to simply put in the max weight - you should always use the recommended amt based on weight and if you don't know the weight use the tire pressure recommended located on your door panel. When I bring my rig in to tire shop I always tell them what pressure I want and B4 I leave I ask them to double check. It's no big deal - just take a little due diligence.

If it's on a Ford chassis 110psi sounds a bit high. I run 80psi in he tires on our 38' coach on the F53 chassis with a 20,500lb GVWR
Good luck and safe travels...

The only way to tell the correct air pressure is to have the coach weighed on all four corners, or the total front and rear axle weight as an alternative. Once you have the actual weight, when fully loaded with full fuel, all occupants, and all of the items that you usually travel with, the various tire charts will tell you the correct tire pressure.

Yes, you are 100 % correct however I have always followed Winnebego's recommendation for pressure on the drivers door and have never had an issue in my last 15 years of MH travel.

I think after 60 years they probably know a little something about it...

So Winnebego knows better than the tire manufacture?

Yes the right way is to inflate by weight. I've never done that - I use the total axle weight and then consult the inflation chart based on that.

As an aside, I don't know why tire shops do that. Every time I get my car or truck back there's 40 psi in the tires. Should be 32 on both.

Yep, same here. New tires on the Yukon, 40psi from the shop. New tires on the Talon, 40 psi from the shop. New tires on the RV, 110 psi from the shop. I have tried to "explain" it to them very nicely, but they always go to what's on the side of the tire, and will argue with me. So I've stopped trying and just deflate them myself. Last time I was letting the air out of my new tires on the Yukon in their parking lot, getting them down to 34 psi.

If the tires are properly inflated, based on the actual weight, do not be concerned about the pressure increasing due to heat.

I believe the Adventurer 37f calls for 100 #'s in the front steer tires and 90 #'s in the rear drive tires.
If in doubt refer to plate on drivers door. It is listed there.
