Your speedo will be off by .7mph at 20mph. That difference will increase as you go faster. With 33s you should definitely flash the vehicle. Your transmission shift points will also be off if you don't.Another question I have is would I need to do any change to the programming of the Wrangler to adjust for the new tire size? Or is it a negligible enough change to where it won’t affect the speedo?
