Important safety information - read before proceeding

•Always ensure the vehicle is on a flat surface before working on tires.
•Allow tires to cool before measuring pressure to avoid inaccurate readings.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Inconsistent tire pressure readings on the vehicle display
•Possible abnormal tire wear
•Decreased handling and stability during driving
•Flat tire or notable loss of air pressure in one or more tires

Diagnostic Steps

1
Use the Tesla touchscreen to check the current tire pressure readings for all tires.
2
Visually inspect each tire for visible signs of damage or punctures.
3
Verify that the valve stems on all tires are not leaking or damaged.
4
Use a tire pressure gauge to manually check the pressure of each tire.
5
Check for any stored error codes related to the TPMS using the vehicle's diagnostic tool.
6
Reset the TPMS through the vehicle settings after ensuring proper inflation.

Solution

Solution

1. Preparation

Gather tools and equipment: tire pressure gauge, air compressor, TPMS reset tool (if needed).
Park the vehicle on a flat surface and ensure the tires are cold (not driven recently).

2. Check and Adjust Tire Pressure

Remove valve caps from each tire.
Use the tire pressure gauge to measure the pressure of each tire.
Compare the readings against the manufacturer-recommended psi, found on the driver’s side door jamb.
If any tire is below the recommended pressure:
- Use an air compressor to inflate the tire to the correct psi.
- Replace the valve cap securely after inflating.

3. Inspect and Repair Tire Damage

If a tire shows signs of damage or puncture:
- Remove the tire from the rim using a tire changing tool.
- Inspect for punctures or sidewall damage.
- If repairable, use a tire plug kit or patch kit to seal the puncture.
- If non-repairable, replace with a new tire.

4. Reset TPMS

Turn on the vehicle and navigate to the 'Service' menu on the touchscreen.
Select 'TPMS Reset' and confirm the reset.
Drive the vehicle for a short distance (usually around 10-15 minutes) to allow the system to recalibrate.
