Solution

1. Tire Inspection and Adjustment

Sub-steps:
1. Check tire pressure using a tire gauge.
2. Inflate or deflate tires to reach manufacturer's recommended pressure (usually found on the driver's side door jamb).
3. Examine tires for any visible damage such as bulges, cracks, or foreign objects.

2. Tire Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Mount each wheel onto a wheel balancer.
3. Adjust weights on the rim to achieve balance as indicated by the balancer.
4. Reinstall wheels onto the vehicle, ensuring they are torqued to manufacturer's specifications (typically 90-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Use an alignment tool to measure camber, caster, and toe angles.
3. Adjust the alignment settings to meet factory specifications.
4. Lower the vehicle and test drive to confirm improvement.
