Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressure and inflate to the recommended PSI if low.
Inspect tires for uneven wear; replace if necessary.
- Sub-steps:
  1. Use the lug wrench to loosen the lug nuts slightly before lifting the vehicle.
  2. Jack up the vehicle and secure it with jack stands.
