Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Check each tire for visible signs of damage (bulges, cuts, etc.).
2. Measure tread depth across the tire; replace tires if tread is below 2/32 inch.
3. If tires are damaged or worn unevenly, replace them with new tires of the same specification.

2. Tire Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Take the wheels to a tire shop for professional balancing.
3. Reinstall the wheels using a torque wrench to tighten bolts to manufacturer specifications (typically 129 lb-ft for Model Y).

3. Wheel Alignment

Sub-steps:
1. After balancing, take the vehicle to a certified alignment shop.
2. Have the alignment adjusted according to the manufacturer’s specifications.
3. Confirm that the camber, toe, and caster are within acceptable ranges.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect the suspension components, including struts, shocks, and control arms, for wear or damage.
2. Replace any damaged or worn components with OEM parts.
3. Ensure that all bolts and nuts are torqued to the manufacturer specifications.
