2. If any tire is damaged, safely jack up the vehicle and remove the wheel using a lug wrench.
3. Replace with a new tire that matches the specifications for the vehicle.
4. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

4. Clean and Inspect Undercarriage

Sub-steps:
1. Use a pressure washer or hose to clean the undercarriage of any debris or fluid buildup.
2. Inspect brake components for signs of excessive wear or overheating, which could contribute to a burning smell.
3. Replace any worn brake pads or rotors as necessary.
