Also need to weigh all four corners to see what actual weight on each tire is and adjust pressure accordingly.

I have a 24,000 lb chassis running Michelin XRV 235/80R 22.5 at 95 front 90 rear. Tracks beautifully.

Good luck, and............

Happy Trails!

The pressure on the wall chart is only useful if you've never weighted the rig. It's the minimum pressure for the maximum loaded weight of the RV. If your actual weight is below that then you have too much pressure in the tires.
Also, all tires on an axle must have the same pressure and it should be the pressure required for the heaviest side.
Almost every RV tire manufacturer publishes an RV Tire Guide. I have them for Michelin, GoodYear and Toyo, plus some of the lesser used brands. EVERYONE should get one or download it off the Internet, it answers mostr of these type questions.

Could've been factory defect, under inflated, over inflated, loose lugs, alignment, shocks...there just isn't any way to truly tell anyone what tire to buy and be 100% assured through your recommendation that nobody will ever have a problem. So, weigh your coach (all four sides) and use factory inflation recommendations for whatever brand of tire is your choice. And just know you will never have 100% peace of mind. All man made devices are prone to failure. I truly believe unless you evaluate your own vehicle weight and use correct PSI's for that weight, nobody here can give you accurate information...only the brand of tire they won't buy again.
Could not have said it better myself. I have used Michelins for years with very good success. I am very fussy about tire maintenance and not trying to get every ounce of life from them. Works for me, maybe I've just been lucky.

Well here is the rest of the story! First, thanks for all the help. After speaking w/ the warranty/ tech in South Carolina, he assured me that based on the corner weights that I gave him he suggested that I had way too much air in all the tires. WHO would have ever thought that! NOT ME. OK 102 in the fronts and 90-95 in the rear. Hooked up the Silverado to the bar and went for a 80 mile round trip. What a difference, a good step in the right direction. I think I'll buy some scales and hit the road.
Thanks again, Dennis

I've been running our Michelins at the recommended pressure plus 5 psi just to have a reserve in case they leak down. Since I check the tires every day before moving and watch the temps I may drop the 5 psi extra and see what it does for the handling/ride.

I bet you can't tell the difference on changing a 100 psi tire pressure by 5 psi. Maybe a 10 psi change you can start feeling the difference.

I guess I'll find out won't I?
