WHEEL AND TIRE DIAGNOSIS | ||||
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 *Rapid wear | *When a patch of tread has loosened, it is torn off the tire by centrifugal forceat high speed | *Incorrect camber angle *Improper camber and toe-in *High-speed turns |
WHEEL AND TIRE DIAGNOSIS | ||||
FLAT SPOT | FEATHERING | BAD PLUGGING | UNEVEN TIRE WEAR | TOTALLY UNSAFE TIRE |
 |  |  |  |  |
*Caused by high-speed braking hard enough to lock up the wheel | *Excessive Toe-in or Toe-out | *Using more than one plug in a leak distorts the tread, resulting in carcass failure | *Bad wheel balance, fault in suspension, and steering gear or bearing | *Tread worn below the limit |
