Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety glasses and gloves.

2. Tire Rotation

Sub-steps:
1. Loosen the lug nuts on all tires slightly using a socket wrench.
2. Raise the vehicle using a jack and secure it on jack stands.
3. Remove the tires and inspect for any damage.
4. Rotate the tires to a different position to promote even wear.
5. Reinstall and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment and have the technician adjust the camber, caster, and toe settings according to Tesla specifications.
3. Verify that the alignment is within the acceptable range post-adjustment.

4. Suspension Inspection and Repair

Sub-steps:
1. If excessive wear is found on any suspension components, replace them as necessary (e.g., control arms, bushings).
2. Recheck the alignment after any suspension repairs to ensure proper setup.
