⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked securely before inspecting tires.
•Use caution when handling sharp objects or using tools.

Symptoms

•Tire tread depth below the recommended level
•Uneven tire wear patterns
•Frequent loss of tire pressure
•Vibration or noise while driving
•Cracks or bulges in the tire sidewalls

Diagnostic Steps

1
Inspect the tire tread depth using a tread depth gauge or the penny test.
2
Examine each tire for uneven wear patterns, such as worn edges or centers.
3
Check tire pressure with a tire pressure gauge and compare it to the manufacturer's specifications.
4
Visually inspect the tires for any cracks, bulges, or other signs of damage.
5
Look for the age of the tires; check the DOT code on the sidewall to determine the manufacturing date.

Solution

Diagnostic Steps

Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools: tire pressure gauge, tread depth gauge, and a flashlight for inspection.

2. Check Tire Tread Depth

Use a tread depth gauge: Insert it into the tread grooves at multiple locations across each tire.
Alternatively, use the penny test: Place a penny with Lincoln’s head down into the tread. If you can see the top of Lincoln’s head, the tread is too worn, and new tires are needed.

3. Inspect for Uneven Wear

Examine each tire for signs of uneven wear:
- Look for worn edges indicating under-inflation.
- Check for center wear suggesting over-inflation.
- Use a flashlight to inspect for any unusual patterns such as cupping or scalloping.

4. Check Tire Pressure

Remove the valve stem cap from each tire.
Use a tire pressure gauge to measure the pressure and compare it to the recommended PSI listed in the owner’s manual or on the driver’s side door jamb.
Inflate to the recommended level if necessary.

5. Inspect for Damage

Visually check each tire for cracks, cuts, or bulges in the sidewalls.
Run your hand along the tire to feel for any irregularities or lumps.
If any damage is found, consider replacing the tire.
