Irregular or Premature Wear
Irregular or premature tire wear has many causes.
| • | Incorrect inflation pressure may cause irregular or premature tire wear. |
| • | Lack of regular rotation may cause irregular or premature tire
wear. |
| • | Driving habits may cause
irregular or premature tire wear. |
| • | Improper wheel alignment
may cause irregular or premature tire wear. |
Inspection Procedure
- Inspect the front tires for irregular or premature wear.
- Inspect the rear tires for irregular or premature wear.
- Rotate the tire if any of the following conditions are evident:
| • | Uneven wear exists across the tread of any tire. |
| • | The left side tire wear and the right side tire wear is unequal. |
| • | A scheduled maintenance interval. |
- Perform a wheel alignment if the following conditions exist:
| • | The left side and/or the right side front tire wear is unequal. |
| • | The wear is uneven across the tread of the tire. |
| • | The tire treads have a scuffed appearance with feather like edges
on 1 side of the tread ribs or the blocks. |
Tread Wear Indicators
The original equipment
tires have built in tread wear indicators to show when you should replace
the tires.
The location of these indicators are at 72 degree intervals around the
outer diameter of the tire. The indicators appear as a 6 mm (0.25 in)
wide band when the tire tread depth becomes 1.6 mm (2/32 in).
