Diagnostic Steps

1
Verify the tire pressure using a digital tire pressure gauge.
2
Check the manufacturer's recommended tire pressure for cold conditions.
3
Inspect tires visually for any physical damage or abnormal wear.
4
Monitor the ambient temperature and correlate it with tire pressure readings.
5

Solution

1. Preparation

Gather tools: digital tire pressure gauge, air compressor, tire repair kit (if necessary).
Ensure the vehicle is parked on a level surface and the tires are cold (not driven for at least 3 hours).

2. Check and Adjust Tire Pressure

Sub-step 1: Use the digital tire pressure gauge to measure the current pressure of each tire.
Sub-step 2: Compare the readings to the recommended cold tire pressure (found on the driver’s door jamb or in the owner's manual).
Sub-step 3: If the tire pressure is below the recommended level, use the air compressor to inflate the tires to the correct pressure.
- Note: Do not overinflate; check pressure frequently while inflating.

3. Reset TPMS

Sub-step 1: Access the vehicle settings on the Tesla touchscreen.
Sub-step 2: Navigate to the 'Service' menu and select 'Tire Pressure Monitoring System.'
Sub-step 3: Follow the prompts to reset the TPMS to ensure accurate readings.

4. Monitor Tire Condition

Sub-step 1: After adjusting the pressure, drive the vehicle a short distance to allow the TPMS to calibrate.
Sub-step 2: Check the tire pressure readings again after a short drive to ensure they remain stable.
