Solution

1. Tire Inspection

Sub-steps:
1. Remove the wheel covers (if applicable) using a flathead screwdriver.
2. Inspect each tire for signs of damage such as cracks, bulges, or uneven wear patterns.
3. Measure tread depth using a tread depth gauge; replace tires if tread is below 2/32 inches.

2. Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to measure the current pressure of each tire.
2. Inflate or deflate tires to match the recommended pressure found on the driver’s side door jamb.
3. Recheck tire pressure after adjustments.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel from the vehicle using a socket set to loosen lug nuts.
2. Take the wheel to a tire shop for balancing.
3. Reinstall the wheel after balancing, ensuring lug nuts are torqued to manufacturer's specifications (typically 100-120 ft-lbs).

4. Suspension Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect suspension components including struts, shock absorbers, and control arms for signs of wear or damage.
3. Replace any worn or damaged components as necessary.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure the alignment is adjusted to manufacturer's specifications.
