Hello, Awaiting delivery of a new Yaris Cross Excel model.
I would like to know if the speedometer is adjusted by Toyota to allow for the difference between wheel sizes as I notice on my current 2021 Yaris seems to be 2mph lower when Speed indication display a different reading to what my speedometer shows?
Wheel size makes no difference to the speedometer reading because larger wheels have lower profile tyres so that the overall diameter remains the same.
