- Check for uneven tread wear patterns that could indicate misalignment or imbalance.
Tools Required: Tire pressure gauge, visual inspection.

3. Tire Pressure Adjustment

Sub-steps:
- Use a tire pressure gauge to check the pressure of each tire.
- Inflate or deflate tires to match the recommended pressure listed on the driver’s door jamb.
Tools Required: Tire pressure gauge, air compressor or tire inflator.

4. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle.
- Take the wheels to a tire shop or use a wheel balancer to ensure they are properly balanced.
- Reinstall the wheels after balancing.
Tools Required: Lug wrench, wheel balancer (if doing it at home).
