Diagnostic Steps

1
Inspect tread depth using a tread depth gauge or the penny test
2
Visually examine the tires for any signs of cracks, bulges, or punctures
3
Check for uneven wear patterns across the tire surface
4
Monitor tire pressure using a tire pressure gauge
5
Drive the vehicle to assess for any vibrations or unusual noises while in motion

Solution

1. Preparation

Gather necessary tools: tread depth gauge, tire pressure gauge, flashlight for inspection.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect Tread Depth

Use a tread depth gauge to measure the depth across multiple points on each tire.
If using the penny test, insert a penny into the tread with Lincoln's head facing down; if the tread does not cover Lincoln’s head, it indicates the need for new tires.

3. Visual Inspection

Check each tire for cracks, bulges, or punctures. Shine a flashlight to identify any hidden damage.
Look for signs of uneven wear, such as cupping or bald patches, which may indicate alignment or suspension issues.

4. Check Tire Pressure

Use a tire pressure gauge to check the air pressure in all tires.
Compare the readings to the manufacturer’s recommended pressure (found in the owner’s manual or on a sticker inside the driver’s door).
Inflate tires to the recommended pressure as needed.

5. Test Drive

Take the Highlander for a short drive to listen for any unusual noises or vibrations.
If any irregularities are noted, further inspection or replacement may be necessary.
