Inspect tires thoroughly: Look for any signs of damage or overheating.
- If tires are damaged:
- Remove the wheel: Loosen lug nuts and lift the vehicle using a jack.
- Replace the tire: Install a new tire ensuring proper alignment and torque lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

4. Address Electrical Issues

Inspect wiring: Look for any melted insulation or exposed wires.
- If damaged, replace any affected wiring or connectors.
- Use electrical tape or heat-shrink tubing to insulate any repaired areas.
