Depends on the place. It is electornics you are messing with, if it does change your wheel size.

My guess, if you go to Chevy, they can do it, you go to a Gas Station, I highly doubt it.

unless the overall diameter changes you'll be ok. there is a differance of almost 1/2" in my stock tire size and the 285/40/17s i have now. at 70mph it throws my speedo off by only .8mph even less than that at slower speeds.
