Tow Vehicle Tire Pressure

I finally broke down and replaced the OEM tires on my Tundra yesterday. I now have E rated Michelin LT tires. The dealership pressurized them to around 36 psi. The max capable rated load occurs at 80 psi. While I usually run my tires at the max pressure, previously 44psi, I am reluctant to inflate these tires to 80psi. I realize I will not have the max rated load capability at less than 80psi. I probably don't need that capacity anyway. It far exceeds my truck's other limitations. Is there an official recommendation on an appropriate tire pressure to run in my situation? I do realize there may be a limit on the pressure my wheels are rated at. I cannot find that figure either. Please note I am not trying to start another truck capacity thread. Thanks!

The plate inside the front door of my F 250 states the recommended PSI for front and back. Does yours not show the recommended pressure?

Your factory wheels may be a limiting factor. I wouldn't pressurize to 80 pounds until I was sure the factory wheels are rated for 80 psi. And make sure you have valve stems rated for 80 psi.

I also replaced my Wranglers with Michelin LTX tires yesterday.Dealer told me I should get over 100,000 KMS out of them which would be great considering there was less than 50,000 KMS on the Wranglers and they were getting quite worn. I guess time will tell.

The recommendations on the truck's label is for the original tires. I will try 60psi for a baseline. I will keep trying to research the wheel and valvestem limitations. The valvestems have transmitters for the low tire pressure monitoring. Thanks!

If you still have the stock rims I wouldn't go over 44 (max stock tire psi) until you find out the rim's max rating. You will never need 80 and even 50 should easily cover your max payload + truck weight.

The max pressure the wheel can take is usually stamped on the back of the wheel. You might check there first.

I have run the E rated tires on my 1/2 ton Avalanche at 65 psi for the past 3 years with great results..

Depends if you are running empty or loaded, I would expect that you should be around 40 psi when running around town, maybe 45 psi on the front axle with the weight of the engine,

When you tow, with your truck should probably be around 65 psi front and rear.

Running around town with 65 psi will just make for a bumpy ride.

I cant speak for the Tundra but I run the 65 psi front and rear on my Avalanche towing or not and I am not bouncy.
