just bought an 07.5 LMM Sierra 2500HD. will be here for the massive amounts of information.

anyone know how far my speedometer is off if the truck has 275/75 on it? i wonder if it will void my warranty to fix that or if the dealer can reflash me to put it back in spec.

:welcome::welcome2::beerchug: Try the wheel and tire section, and do a search. Good Luck with the new truck.
