Tire Inspection

Irregular and Premature Wear

Irregular and/or premature wear results from many causes including the following: incorrect inflation pressures, non-rotated tires, rough driving and improper wheel alignment.

If the following conditions are noted, tire rotation is necessary:

- Front tires wear differently from rear tires.
- Uneven wear between both sides of tread on the same tire.
- Both front tires wear unevenly.
- Both rear tires wear unevenly.
- Abnormal wear such as cupping and flat spotting is noted.

Wheel alignment should be checked if the following conditions are noted:

- Front tires wear unevenly.
- Uneven wear between both sides of tread on the same front tire.
- Front tire treads show scuffs with "feather" edges on one side of tread ribs or blocks.










Wear Indicator

Originally installed tires have built-in tread wear indicators (1).

These indicators appear as 7 mm (0.27 in) wide bands when the tire tread depth becomes 1.6 mm (0.063 in).

If a tire has indicators (1) appearing across 3 or more tread grooves at 6 locations, replacement of the tire is recommended.
