Tire Diagnosis. Chevrolet Metro 1998

For 1990-2009 cars

#### Hard Cornering, Underinflation, Lack of Rotation

#### Heavy Acceleration on Drive Axle, Excessive Toe on Drive Axle, Lack of Rotation

#### Excessive Toe on Non-Drive Axle, Lack of Rotation

Irregular and premature tire wear has many causes. Some of them are:

• | Incorrect inflation.

• | Lack of regular rotation.

• | Incorrect pressures.

• | Driving habits.

• | Improper wheel alignment.

If the wheel alignment is reset due to tire wear condition, always reset the toe as close to 0 degrees as the specification allows.

If the following conditions are noted, rotate the tires:

• | The front tire wear is different from the rear tire wear.

• | The left and the right front tire wear is unequal.

• | The left and the right rear tire wear is unequal.

Check the wheel alignment if the following conditions are noted:

• | The left and the front tire wear is unequal.

• | Wear is uneven across the tread of any front tire.

• | The front tire treads have a scuffed appearance with feather edges on one side of the tread ribs or blocks.

### Tread Wear Indicators

The original equipment tires have built-in tread wear indicators (1) to show when the tires need replacement. These indicators (1) will appear as bands when the tire tread depth becomes shallow. When the indicators (1) appear in three or more grooves at six locations, tire replacement is recommended.
