SHOULDER WEAR
CUPPING
SERVICE PROCEDURE
1.
Tire wear should be inspected:
A.
If only slight cupping is noticed, and the cross grooves in the tire's outside shoulder are still visible (see Figure 1), the tires should be rotated.
The modified "X" pattern should be used (See Figure 2). This method will best equalize wear after a few thousand miles.
