I wanted to go to 10" wheels and 325/60r20 tires(35 x 13.5) which everything I've looked at is 8 ply instead of 10 and has a max psi of 65.
I just mounted some 35/13.5/18 pro comp xtreme at's they are load E and I have them aired up to the 65lbs max and the light is on.
I just did the tire retraining, the light is still on, but the manual said it could take up to 20 minutes of driving for it change?
My installer would not let me mount all the sensors in the spare, soo I couldn't try to air that one up to 80 to see if that works.
