Verify the customer concern by performing a road test on a smooth road. If any vibrations are apparent, go to NOISE, VIBRATION & HARSHNESS .
To maximize tire performance, inspect for signs of improper inflation and uneven wear, which may indicate a need for balancing, rotation, or front suspension alignment.
Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering, excessively rapid acceleration and unnecessary sharp braking increases tire wear.
Replacement tires must follow the recommended:
- Tire sizes.
- Speed rating.
- Load range.
- Radial construction type.
Use of any other tire size or type can seriously affect:
- Ride.
- Handling.
- Speedometer/odometer calibration.
- Vehicle ground clearance.
- Tire clearance between the body and chassis.
- Wheel bearing life.
- Brake cooling.
Wheels need to be replaced when:
- Bent.
- Cracked.
- Dented.
- Heavily rusted.
- Leaking.
- They have elongated wheel hub bolt holes.
- They have excessive lateral or radial runout.
Wheel and tire assemblies are attached by eight integral two-piece swiveling wheel nuts.
