Wheels and Tires: Testing and Inspection

PARAMETER SETTING PROCEDURE WHEN TIRE SIZE IS CHANGED

CAUTION:
- If the wheel and tire sizes are changed, a discrepancy with the speedometer needle whereby it exceeds the allowable range could result in a malfunction. If the wheel and tire sizes are changed, perform the following procedure to change the tire size parameter setting.
- The same parameters should be set in "Tire dimension", "Tire Circumference", and "Tire Size".
