Condition
Some subject models with original equipment all season tires may experience premature/irregular tire wear on non-drive axles. The wear may be
identified as a cupping condition, usually on the outer shoulder of the tire. If allowed to continue, premature wearout of tread may occur.
Cause
The single, most contributing cause of this type of wear, except for abusive driving, is excessive toe-in. Lack of tire rotation and low inflation pressures
will also exaggerate this condition.
Vehicles Involved
The following models that are equipped with All Season Firestone "Supreme", General "Ameriway XT", Goodyear "Vector", or Uniroyal "Tiger Paw
