Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather tools and parts needed for the repair.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts on the wheels while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheels and inspect each tire for damage and wear.
4. Replace any damaged tires with new ones that meet the manufacturer's specifications.
5. Reinstall the wheels and hand-tighten the lug nuts.
6. Lower the vehicle and torque the lug nuts to the specified value (usually around 76 ft-lbs for Toyota).
