Hey all!!! I have a customer here with an 07 LMM :D ! He changed tire size. Went from a LT265/70R17E to a 33x12.50R18LT. I know that this isn't the place to post this, but you guys are all about aftermarket calibrations. Do you know where to go to have this tire size correction made. GM does not support this tire size because it was not an option when sold new. Thanks :)
