Solution

1. Preparation

Gather necessary tools: tread depth gauge, air pressure gauge, and flashlight.
Park the vehicle on a flat surface and ensure it is in "Park" or neutral with the parking brake engaged.

2. Measure Tread Depth

Use a tread depth gauge to measure the depth in several locations across the tire.
If the depth is less than 2/32 inches, replacement is necessary.

3. Inspect for Uneven Wear

Examine each tire for signs of uneven wear, such as excessive wear on one side or in the center.
If uneven wear is detected, assess the alignment and suspension components for issues before replacing tires.

4. Check Sidewalls

Inspect each tire's sidewall for any cracks, bulges, or punctures.
Replace tires with any signs of serious sidewall damage.

5. Assess Vibration and Noise

During a test drive, pay attention to any unusual vibrations or noise, which may indicate tire imbalance or damage.
If issues are persistent, consult a professional for further diagnosis.
