Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure the pressure of each tire.
2. Inflate or deflate each tire to match the recommended pressure specified in the owner’s manual.

2. Wheel Alignment

Sub-steps:
1. Drive the vehicle to a professional alignment shop.
2. Have the technician perform a four-wheel alignment according to manufacturer specifications, adjusting camber, caster, and toe as needed.

3. Suspension Inspection and Repair

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Inspect all suspension components visually and by feel for play or damage.
3. Replace any worn or damaged components (e.g., bushings, ball joints).
4. Reassemble suspension components and lower the vehicle.

4. Tire Rotation or Replacement

Sub-steps:
1. If tire wear is significant, consider rotating tires to even out wear.
2. If tires are excessively worn, remove them using a tire iron to loosen lug nuts.
3. Install new tires ensuring proper fitment and torque lug nuts to the manufacturer-recommended specifications.
