Opps, I ‘meant’ TRIP in terms of MPG, not odometer. I meant to ask if/how do you adjust the OEM MPG computer for the large diameter wheel size.
I don't. My taller aftermarket wheels/tires are closer to the actual dimensions used by the speedometer/odometer, so my speedometer is more accurate now. I assume, but don't know for sure, that the trip computer uses the same parameters.
BTW, I traded in my stock 17" wheels/tires to the dealer when I bought the car.
