When moving up to a larger tire size (diameter), can the dealer reset the Jeep's computer to the new diameter so that the mileage calculator in the overhead console will read correctly?

I thought I read on another post that this could also be done by any shop with a diagnostic machine. Anyone know?

Thanks

Yep, they need the new tire dimensions, do a little math and reset the computer.
