Not sure I understand, are you saying it does not work? Here is an example: If you have 8 inch wheels, I suspect your tires are 18 - 18.5 inches in diameter. It should say on the tire or you can measure a tire where the magnet is attached. Lets say tire is 18".

18 in -> 457.2 mm

457.2 * 3.1416 = 1436

Enter 1436 into the speedometer.

If tires are 18.5 then enter 1476 (469.9mm * 3.1416)
