WHEEL AND TIRE DIAGNOSIS

CENTER OF TREAD WORN	CENTER OF TREAD WORN	BOTH SIDES OF TREAD WORN	CHUNKING OF TIRE	ONE SIDE OF TIRE WORN
*Over- inflation	*Center- tread down to fabric due to excessive over- inflation	Under- inflation Bulge at the shoulder *Wear rapidly	*When a patch of tread has loosened, it torn off the tire by centrifugal force at high speed	*Incorrect camber angle

FLAT SPOT	FEATHERING	BAD PLUGGING	UNEVEN TIRE WEAR	TOTALLY UNSAFE TIRE
*Caused by heavy braking which makes the wheels lock and scrubs the tires along the road surface	*Excessive TOE-IN TOE-OUT	*Using more than one plug distort the tread, resulting in carcass failure	*Bad wheel balance, fault in suspension, steering gear or bearing	*Tread worn below the limit
