Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, wheel balancer, alignment tools.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged before lifting it.

2. Tire Pressure Adjustment

Check the recommended tire pressure in the owner’s manual.
Use a tire pressure gauge to measure each tire's pressure.
Inflate or deflate tires to the recommended pressure as necessary.

3. Tire Inspection and Replacement

Remove the wheel covers if applicable.
Inspect each tire for visible damage, such as cuts or bulges.
Check for uneven wear patterns; consider replacing tires if they are worn beyond the tread wear indicators.

4. Wheel Balancing

Mount the wheel on the wheel balancer.
Spin the wheel to check for imbalance.
Add balancing weights as necessary to achieve proper balance.
Reinstall the balanced wheel onto the vehicle securely.

5. Suspension and Alignment Check

Inspect suspension components for wear, including shocks, struts, and bushings.
