Default Tire size/Flash question
I have a '12 jk, 6spd, 3.73's, and stock 16'' wheels....I just picked up a brand new set of jk sahara wheels and tires dirt cheap. Once I put them on, will I need to flash the computer to those size wheels/tires or can I get away with not flashing? If I do have to flash, does anyone in the Baltimore area have a programmer? Can the dealership do it? Thanks!!

Dealership can calibrate speedo for any OEM tire size.

You will be fine. Should not rub at all.
