Solution

1. Preparation

Gather necessary tools: tread depth gauge, tire pressure gauge, flashlight.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is turned off and the engine is cool.

2. Inspect Tread Depth

Use a tread depth gauge and insert it into the grooves of the tire.
If the reading is less than 2/32 of an inch, note that the tire needs replacement.

3. Examine for Damage

Visually inspect each tire for cracks, bulges, or punctures.
If any damage is found, replace the affected tire(s).

4. Check for Uneven Wear

Rotate each tire to inspect the tread pattern.
Look for signs of uneven wear, which may indicate misalignment or suspension issues.
If uneven wear is present, address the underlying issue and replace tires if necessary.

5. Monitor Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate tires to the recommended pressure level if they are low.
If the pressure warning light remains on after correcting tire pressure, further diagnostic checks may be needed.

6. Test Drive

Take the vehicle for a test drive to assess handling and noise.
If excessive vibration or noise continues, consider replacing the tires.
