Solution

1. Preparation

Tools Required: Tread depth gauge, tire pressure gauge, jack and jack stands, torque wrench.
Ensure the vehicle is parked on a flat, stable surface and engage the parking brake.

2. Check Tread Depth

Use a tread depth gauge to measure the depth of the tread on each tire.
Alternatively, insert a penny into the tread groove with Lincoln's head facing down; if you can see all of Lincoln’s head, it’s time for new tires.

3. Inspect Sidewalls

Carefully inspect each tire’s sidewalls for any visible cracks, cuts, or bulges.
If any damage is found, consider replacing the affected tire(s).

4. Measure Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to match the manufacturer's recommended PSI found in the owner’s manual or on the driver’s side door jamb.

5. Examine Tire Wear Patterns

Look for signs of uneven wear, such as excessive wear on the outer or inner edges of the tire.
Rotate or replace tires as necessary based on wear patterns.

6. Conduct a Road Test

Drive the vehicle at various speeds to check for vibrations or unusual noises.
If any issues are noticed, further inspection or tire replacement may be necessary.
