Chevrolet Trax: All seasons tires descriptio

Fig. 16: Identifying All Seasons Tire Marking

Most GM vehicles are equipped with steel belted all-season radial tires as standard equipment. These tires qualify as snow tires, with a higher than average rating for snow traction than the non-all season radial tires previously used. Other performance areas, such as wet traction, rolling resistance, tread life, and air retention, are also improved. This is done by improvements in both tread design and tread compounds. These tires are identified by an M + S molded in the tire side wall after the tire size. The suffix MS is also molded in the tire side wall after the TPC specification number.

The optional handling tires used on some vehicles now also have the MS marking after the tire size and the TPC specification number.

GENERAL DESCRIPTION

The factory installed tires are designed to operate satisfactorily with loads up to and including the full rated load capacity when these tires are inflated to the recommended pressures.

The following factors have an important influence on tire life:

• Correct tire pressures
• Correct wheel alignment
• Proper driving techniques
• Tire rotation

The following factors increase tire wear:

• Heavy cornering
• Excessively rapid acceleration
• Heavy braking

METRIC WHEEL NUTS AND BOLTS DESCRIPTION

Metric wheel/nuts and bolts are identified in the following way:

• The wheel/nut has the word Metric stamped on the face.
• The letter M is stamped on the end of the wheel bolt.

The thread sizes of metric wheel/nuts and the bolts are indicated by the following example: M12 x 1.5.

• M = Metric
• 12 = Diameter in millimeters
• 1.5 = Millimeters gap per thread

P-METRIC SIZED TIRES DESCRIPTION

Replacement tires should be of the same tire performance criteria (TPC) specification number. This will ensure the same size, the same load range, and the same construction as those originally installed on the vehicle.
