Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a flat surface and engage the parking brake.

2. Tire Inspection

Sub-steps:
- Remove hubcaps or wheel covers if necessary.
- Inspect each tire for visible damage, such as bulges or punctures.
- Check tread depth across the entire tire surface.
Tools Required: Tire pressure gauge, flashlight.

3. Tire Pressure Adjustment

Sub-steps:
- Use a tire pressure gauge to measure the pressure of each tire.
- Inflate tires to the manufacturer's recommended pressure (found on the driver’s door jamb).
Tools Required: Air compressor, tire pressure gauge.

4. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle.
- Take the wheel to a tire shop or use a wheel balancer to check for balance.
- Add wheel weights as necessary to correct balance.
- Reinstall the wheel and torque lug nuts to the manufacturer's specifications (usually around 76 ft-lbs).
Tools Required: Torque wrench, wheel balancer.

5. Suspension and Alignment Check

Sub-steps:
- Inspect all suspension components (ball joints, tie rods, shocks) for wear or damage.
- If any parts are worn, replace them as needed.
- Perform a four-wheel alignment if suspension components are within specifications.
Tools Required: Alignment tools, jack and jack stands.
