Do bigger rims mess with speedometer?

You might ask: do bigger tires make your speedometer faster? The answer is no. Tire size and speedometer accuracy are directly linked to each other. Up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed.

How do you set the speedometer on a bigger tire?

Identify the speedometer calibration button and press-hold, crank your vehicle and then release the button. Push the button and drive the distance recommended by the manufacturer. After driving, press the button again, and the speedometer will automatically calibrate itself.
