Measure the tire pressure using the gauge.
Inflate or deflate tires to the manufacturer's recommended pressure as found in the owner's manual or on the door jamb sticker.

3. Tire Inspection and Replacement

Tools Required: Jack, jack stands, lug wrench
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel using the lug wrench.
Inspect the tire for uneven wear or damage. If any issues are found, replace the tire with a new one.
Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
