Ensure the vehicle is on a flat surface and turn off the ignition.
Disconnect the battery if necessary for safety.

2. Inspect and Inflate Tires

Sub-steps:
- Use the tire pressure gauge to check tire pressure.
- Inflate tires to the recommended PSI as stated in the owner's manual.
- Inspect for any obvious damage or bulges in the tires.

3. Check Wheel and Tire Condition

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Inspect the wheels for bends, cracks, or any signs of damage.
- Check for uneven tire wear patterns which may indicate alignment issues.
