CONDITION
Some 1985-1986 Celebrity models, 1985-1986 Caprice and Monte Carlo models, and some 1985-86 light duty trucks with original
equipment all season tires ("M & S" rating on sidewall) 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 wear out 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.
