Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, tire pressure gauge, alignment tools, wheel balancing machine.
Elevate the vehicle using a jack and secure with jack stands.
Remove the wheel covers if applicable.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of all four tires.
Inflate or deflate tires to match the manufacturer’s recommended specifications found in the owner’s manual or on the driver's side door jamb.

3. Wheel Alignment

Tools Required: Alignment machine.
Position the vehicle on an alignment rack.
Adjust the camber, toe, and caster according to manufacturer specifications.
Confirm alignment settings are within acceptable ranges and recheck after adjustments.

4. Wheel Balancing

Tools Required: Wheel balancing machine.
Remove the tires from the vehicle.
Mount each tire on the balancing machine to assess balance.
Add balancing weights as necessary to correct imbalances, then remount tires on the vehicle.

5. Replace Tires (if necessary)

If tread wear is excessive and beyond safe limits, replace tires with new, quality tires appropriate for the vehicle.
Ensure that the new tires are installed properly and inflated to the correct pressure.
