So is mine, but the dealership/port upgraded the computer for new tire size and upped the speed limiter for "h" tire rating. Mine came part of a Gulf Region (the equivilance of TMC antichrist) installed package. Might want to contact the dealer service department before going aftermarket.

I don't think you can go over 285/55/20 without lifting the front. There is also a tire pressure sensor issue if you want to change rims $$$.

Anybody know the largest tire I can put on the TRD 18" rim. I ordered a CrewMax and want to get the BFG A/T TA, with a 3" lift.

I saw a pic somewhere on this forum of a white dc w the 3inch revtek lift and 35 bfg m/t on trd rims. It looked bad a$$!
