Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Safety Warning: Allow tires to cool down before checking or inflating.

2. Inspect Tires

Remove any debris or objects lodged in the tires.
Visually inspect each tire for cuts, bulges, or punctures.
Use a tire pressure gauge to measure the pressure of each tire.

3. Adjust Tire Pressure

Inflate or deflate each tire to the manufacturer’s recommended pressure (usually found on a sticker inside the driver’s door).
Recheck the pressures after adjustment to ensure they are correct.

4. Check Valve Stems

Inspect each valve stem for signs of wear or damage.
Replace any damaged valve stems with new ones if necessary.

5. TPMS Sensor Check

If tire pressure readings are still fluctuating, remove the tires and inspect the TPMS sensors for damage.
Replace any faulty TPMS sensors and ensure they are properly synced with the vehicle.

6. Software Update

Connect the vehicle to Wi-Fi and check for any available software updates.
Install updates if available to ensure TPMS functionality is up-to-date.
