Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Tire Inspection and Maintenance

Sub-steps:
1. Inspect each tire for uneven wear patterns or visible damage.
2. Measure tire pressure using a tire pressure gauge; inflate to manufacturer specifications if needed.
3. Rotate tires if uneven wear is detected to promote even wear.

3. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop for a four-wheel alignment.
2. Have the technician check the balance of all four wheels and adjust as necessary.
3. Test drive the vehicle post-alignment to confirm improvement.
