Solution

1. Preparation

Gather tools and equipment needed for the repair, including a jack, jack stands, tire pressure gauge, and alignment tools.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure of each tire.
2. Inflate or deflate tires to match the recommended psi listed in the owner’s manual.
Tools Required: Tire pressure gauge, air compressor or manual pump.

3. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect tires for uneven wear, damage, or foreign objects.
3. If tires are damaged or excessively worn, replace them with new tires that meet OEM specifications.
Tools Required: Lug wrench, tire iron, replacement tires.

4. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Place wheels on a wheel balancer and spin to identify any imbalances.
