I ran 65 in my rear tires with my pin weight at 3400 pounds and they rubbed together. The result after 600 miles was a big bulge in the sidewall of the tire. They weren't touching in a static setting, but while flexing going down the road, they were touching. Cost me four new tires. The inflation charts and the scientific approach don't mention the tires touching.
Wow, I had never heard of that.
I would say they were not the correct size tires.

Follow what is on the tires, Michelin had a reason for putting that on the tires. What is on the door is wrong if it is not for the brand and size tires you have on the truck.
:S :S :S
The number on the sidewall is for the MAXIMUM LOAD, Michelin provides inflation charts for loads less than the Maximum the tire is designed to carry. Using the proper inflation for the load provides better wear and better traction and control!!!

Just changed from a TT with 1200lb tongue weight to a fifth w approx 4000 pin weight. Haven't gotten to the scale yet. I'm confused.... placard on truck door says tires rated at 2660lbs at 65psi for rear duallies. Michelin load rating says 2778 at 80psi for duals. Should I inflate to 65or 80psi? Didn't have to think about this as much with only 1200lbs. Always kept it at 65.
Well if you inflate to 80 psi that is a total of 11,112# of capacity, do you need that much?
At 65 psi you have 10,640# of capacity, so hit the scale and get your loaded and unloaded weights, my guess is 65 psi is more than enough.

Put your truck on a scale with the 5th wheel hooked up and see what your weights actually are. The go to the Michelin tire inflation chart and determine by your actual weight what your REAL tire pressure should be.
