⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a stable surface and use wheel chocks when lifting the vehicle with a jack.

Symptoms

•Low tire pressure warning light illuminated on the dashboard
•Tire(s) visibly deflated or low
•Unusual noise or vibration while driving
•Decreased fuel efficiency
•Handling issues, such as pulling to one side

Diagnostic Steps

1
Inspect all tires visually for any signs of damage, such as punctures or sidewall bulges.
2
Use a tire pressure gauge to measure the pressure of each tire.
3
Compare the measured tire pressures with the recommended pressure listed on the driver's door jamb or in the owner's manual.
4
Check the tire pressure monitoring system (TPMS) for any error codes using an OBD-II scanner, if equipped.
5
Examine the valve stems for leaks or damage.

Solution

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, OBD-II scanner (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Inflate Tires

Sub-step 1: Identify the tire(s) with low pressure from your measurements.
Sub-step 2: Remove the valve cap from the affected tire(s).
Sub-step 3: Use the air compressor to inflate the tire(s) to the recommended pressure.
- Tools Required: Air compressor.
Sub-step 4: Recheck the tire pressure after inflating to ensure it is at the correct level.
Sub-step 5: Replace the valve cap securely.

3. Repair or Replace Damaged Tires (if applicable)

Sub-step 1: If a puncture or damage is found, assess if the tire can be repaired or needs replacement.
Sub-step 2: For a repair, use a tire plug kit or visit a professional tire service. For replacement, select a tire that matches the specifications.
Sub-step 3: If replacing, ensure the new tire is mounted correctly and balanced.
Sub-step 4: Reinstall the tire onto the vehicle, ensuring proper torque specifications on lug nuts.
- Tools Required: Tire jack, lug wrench, torque wrench.
