I am looking at running a set of 255/85/16 Cooper AT's on the truck. The truck is a 2003 Tacoma TRD 5spd. I have a 6inch suspension lift. I know I will clear them no problem, but will the truck be able to handle them without re-gearing? I have done the deckplate mod, but that's the only thing I have done performance wise. All comments appreciated .
