why does my Tesla Model Y Current (2020-present) have excessive tire wear?

Solution

1. Preparation

• Tools Required: Jack and jack stands, tire pressure gauge, alignment machine, socket set, torque wrench.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Pressure Adjustment

• Sub-steps:
  1. Remove valve caps from all tires.
  2. Use a tire pressure gauge to measure the pressure of each tire.
  3. Inflate or deflate tires to match the recommended pressure found in the owner’s manual or on the door jamb sticker.

3. Tire Replacement (if necessary)

• Sub-steps:
  1. If tires are excessively worn beyond 2/32” tread depth, mark the wheel positions.
  2. Loosen lug nuts while the vehicle is on the ground.
  3. Lift the vehicle using a jack and secure it with jack stands.
  4. Remove lug nuts and take off the worn tires.
  5. Install new tires, ensuring the correct rotation direction is followed.
  6. Tighten lug nuts to the manufacturer’s specified torque (typically between 80-100 ft-lbs).

4. Wheel Alignment

• Sub-steps:
  1. Drive the vehicle to a professional alignment shop or use an alignment machine.
  2. Follow the alignment machine’s instructions to adjust the camber, caster, and toe settings to factory specifications.
  3. After adjustments, double-check all settings and ensure they are within tolerances.

5. Suspension Component Inspection & Replacement

• Sub-steps:
  1. If worn suspension components are found, replace them as needed.
  2. Use a socket set to remove bolts securing the damaged parts.
  3. Install new suspension parts according to the manufacturer’s specifications.
  4. Re-check alignment after any suspension work.
