Tire pressure 245/70 16 XL

Folks,

I did a reasonable amount of searching, but can't really find anything definitive. The recommendations on the door sill seem low, especially for the XL tires.

The best rec so far I've found is from tiresplus and is 32F/35R.

I tow a Miata on a 1000 pound aluminum open trailer. The Tundra doesn't even know it's back there.

Thanks,

 

i run 36 psi all around on BF k02 285/70/17 E rated. I have about 55K miles on them

 

Run 35 psi all around on 265/70R16. Seems like a happy spot. I agree that 29 psi as recommended on the door is low. Did it for a while and slowly increased until it felt right.
