Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, tire pressure gauge, alignment machine.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Safety warning: Allow the vehicle to cool down before working on tires.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all four tires.
Inflate or deflate each tire to the recommended pressure as indicated on the driver’s door jamb label.

3. Wheel Alignment

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a lug wrench.
Connect the alignment machine to the vehicle and follow the manufacturer's procedure to assess and adjust the alignment settings.
Adjust camber, caster, and toe settings as necessary to meet specifications.

4. Suspension Inspection and Repair

Inspect struts, tie rods, and bushings visually for signs of damage or excessive wear.
Replace any worn components with OEM or high-quality aftermarket parts.
Reinstall any removed components and ensure all bolts are torqued to the manufacturer’s specifications.

5. Tire Rotation or Replacement

If the tires are excessively worn, rotate them as per the manufacturer’s guidelines or replace them if tread depth is below the recommended limits.
Ensure that the replacement tires match the specifications for the Tesla Model 3.
