Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the negative battery terminal if working on electrical components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, floor jack, jack stands, torque wrench.
Check tire pressure and inflate to the manufacturer's specifications if low.
Inspect tires for damage; replace if any bulges or excessive wear are found.
If needed, remove the tires using a floor jack and jack stands.
Replace tires with new ones if they are beyond repair.

3. Wheel Balancing

Tools Required: Wheel balancer.
Remove the wheels from the vehicle.
Mount the wheels on a wheel balancer and spin to determine any imbalance.
Add balancing weights as necessary to achieve proper balance.
