ABSTRACT:
Disclosed is a vehicle wheel measuring apparatus, comprising a push rod, a counter, a wheel, and a gear coupled mechanism, wherein the counter is disposed on top of the push rod. Through the gear coupled mechanism, the axle center of said counter and the wheel axle form a joint relationship having the same rotational cycles. A front yoke is attached to the wheel axle in the end of said push rod, and a set of magnetic element is disposed between the wheel axle and the interior side of the front yoke. This prevents the wheel from rotating by itself that affects actual measured distance.
