Tools Required: Jack and jack stands, lug wrench.
Inspect tires for signs of uneven wear or damage. Look for bulges, cracks, or foreign objects.
If tires are damaged, jack up the vehicle and remove the wheel using a lug wrench.
Replace the damaged tire with a new one, ensuring it is properly inflated to the manufacturer's specifications.

4. Exhaust System Inspection

Tools Required: Wrench set, flashlight.
Inspect the exhaust system for any areas where it may be in contact with other components.
Tighten any loose mounts or brackets that may allow movement and contact.
