Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, wheel balancing machine.
Ensure the vehicle is parked on a level surface and the engine is off. Engage parking brake.

2. Tire Inspection and Repair

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Check tire pressure using a tire gauge; inflate tires to the recommended PSI if necessary.
