Wheels and Tires: Description and Operation

General Notes
Factory installed tires and wheels are designed to operate satisfactory when inflated to the recommended inflation pressures; refer to the Specifications sub-section. The recommended pressures apply to vehicle loads up to and including full-rated load capacity.
Correct tire pressures and driving technique have an important influence on tire life. Heavy cornering, excessively rapid acceleration and unnecessary sharp braking increase tire wear.
Replacement tires should follow the recommended:
- size.
- speed rating.
- load range.
- radial construction type.
The use of any other size or type may seriously affect:
- safety.
- ride.
- handling.
- speedometer and odometer calibration.
- vehicle ground clearance.
- tire clearance between body and chassis.
- wheel bearing life.
- brake cooling.
Wheels need to be renewed when:
- impact damaged.
- heavily corroded.
- porous.
- wheel stud holes or seats become damaged.
- they have excessive radial or lateral runout.
