Front Position Tire Wear on Rear-Wheel-Drive Vehicles With All Season Tires
Some rear-wheel-drive vehicles may exhibit premature tire wear on the front tires. The wear usually starts on the outer tread row and may progress
across the full tread. This wear also usually appears as a heel and toe (high and low) wear pattern on individual tread blocks which can eventually lead to
tire noise and/or tire roughness.
Small amounts of heel/toe wear on the outer tread is considered normal. This wear is characteristic of new tires at full tread depth on free-rolling axles..
Turning and cornering exaggerates front tire wear. Routine tire rotation at 7,500 miles using the modified "X" method as shown in the Owner's Manual
will minimize the wear. Such tires can be expected to give optimum performance for their full intended life.
If this type of wear becomes excessive and/or results in a customer inquiry, the following procedure should be used:
FIGURE 1
1.
Rotate tires using the modified "X" pattern shown in Figure 1. This allows the front tires to wear in the opposite direction on the rear of the vehicle
which will tend to even out any irregular wear quicker. It also allows all four tires to eventually run on all four positions. Tire noise may continue
after rotation, but should gradually lessen after a few thousand miles.
2.
Measure front wheel alignment. The single most contributing cause of premature tire wear, except for abusive driving, is excessive toe. For best
