More then likley not, you have to send your PCMforless can change it, and while they have it, you should get a tune as well.

i had the son of a neighbor,( he is a chevy cert. mech.), recalc. mine when i went to larger tires.(245 to 265's)
not sure what he instrument he used, but it's the hand held diagnostic computer that they have @ the dealership
IIRC 06 or 07 and up can be recalc'd :twocents:

I am pretty sure that only the Tech II and similar high-end scanners are the only ones that can change the calibrations.

to the OP, yes a TechII can be used on 06 and newer to change the tire size for calibration.
