Finally bit the bullet and bought some new Toyo's(285/55/20).. Just wondering what some of you are running for air pressure?? The new tires have a max rating of 80psi compared to the stock P-rated tires that were only around 45psi.They only put 35psi in the tires since that's what is on the door sticker. But I'm thinking it should be higher?? I'm not really worried about a harsher ride with more air pressure. I just want to know what air pressure to keep them at to get the most miles out of the them.
Thanks,
Kev

I run 42 in my DuraTracs unloaded based on the chalk test. BTW, are those WeatherTech mud flaps?

ROT (Rule Of Thumb) is if you don't know what PSI to use, go with 80% of the maximum tire pressure on the sidewall and monitor tread wear.

I run 45 PSI, seems to work reasonably well. You can always bump them up if towing.

Part of the concern is what your stock wheels can handle. Just because the tires can hold 80psi doesn't mean the wheels can.
I run 10-ply tires and stock 20" wheels as well. For towing I've been trying different weights and so far 60 in the front and 65 in the rear has been pretty good. Definitely firm when not towing and I'd recommend less for daily use.
