Hey guys-
Getting ready to pull the trigger on some new tires for my 07 DC.
Since we pull a fifth-wheel we are going to ditch the "P" rated tires and move up to a "E" rated tire.
Probably Michelin LTX M/S 275/65R18.

I have heard mention on this forum that each wheel has a pressure rating.
How do I know what that rating is for my current wheels?

I know the tire is rated for a max pressure of 44psi (cold).
If the new tire is rated at 80 psi (cold) how do I know if the wheel can handle this pressure?

The wheels can handle far more than the 80psi. The weakest point on that kind of install is the tire valve which can do well over 80psi as well.

when towing my TT, which is about 7500 lbs.........i run 65lb in my 10 ply tires. i was always told that you dont want the tire to squat very much. this will cause unwanted wear and additional heat.

I probably should have qualified my previous post. Can your wheels run 80psi? It doesnt matter. Any load a Tundra can do would not need anymore than 65psi. I don't know of any modern wheel that cannot handle 65psi. So you should be just fine.

i would imagine the wheel can withstand a hell of alot more pressure than the tire can.......
