⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety gloves and goggles when handling tires.
•Always ensure the vehicle is on a stable surface when using a jack.
•Be cautious of hot tires after driving; allow them to cool before inspecting.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible decrease in fuel efficiency
•Uneven tire wear
•Vehicle handling issues, such as wandering or pulling
•Tire noise may be amplified during driving

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or deformities.
3
Verify if the tire pressure monitoring system (TPMS) is functioning correctly by using an OBD-II scanner to check for any fault codes.
4
Reset the TPMS using the vehicle’s onboard system or a TPMS reset tool if no faults are found.
5
Check for any leaks around the valve stems and tire bead area.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and the engine is off.
Safety warning: Always wear safety gloves and goggles when handling tires.

2. Check and Inflate Tires

Tools Required: Tire pressure gauge, air compressor.
Sub-steps:
1. Remove the valve cap from each tire.
2. Use the tire pressure gauge to measure the current tire pressure.
3. Compare the measured pressure with the recommended PSI listed in the owner’s manual or on the door jamb sticker.
4. If tire pressure is low, use the air compressor to inflate the tires to the recommended PSI.
5. Replace the valve caps after inflation.

3. Inspect and Repair Tires

Tools Required: Tire repair kit (if needed), jack and jack stands.
Sub-steps:
1. If any tire is visibly damaged or punctured, safely lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel with the damaged tire.
3. Inspect the tire for punctures or sidewall damage.
4. If a puncture is found, follow the tire repair kit instructions to patch or plug the tire.
5. If the tire is severely damaged or worn, replace it with a new tire.

4. Reset TPMS

Tools Required: OBD-II scanner (if necessary), or follow the vehicle's manual for TPMS reset.
Sub-steps:
1. Start the vehicle and navigate to the TPMS reset option in the vehicle settings using the infotainment system or dashboard controls.
2. Follow the prompts to reset the TPMS.
3. If using an OBD-II scanner, connect it and select the TPMS reset function according to the scanner’s instructions.
