Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool before working on tires or brakes.
•Wear safety glasses when using tools and handling tires.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Visible tire deflation or flat appearance
•Frequent need to inflate tires
•Poor handling or increased road noise
•Uneven tire wear

Diagnostic Steps

1
Inspect each tire visually for signs of damage such as cuts, punctures, or bulges.
2
Use a tire pressure gauge to check the current pressure of all tires.
3
Apply a soap and water solution to the tire sidewalls and tread to identify air leaks (look for bubbles).
4
Check the valve stems for cracks or damage that could allow air to escape.
5
Inspect the tire bead area where the tire meets the rim for signs of corrosion or improper seating.
6
Verify that the TPMS (Tire Pressure Monitoring System) sensors are functioning correctly.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, soap and water solution, tire repair kit, and jack.
Ensure the vehicle is on a flat, stable surface, and engage the parking brake.

2. Remove Tire (if necessary)

Loosen the lug nuts using a socket set.
Lift the vehicle using a jack and secure with jack stands.
Completely remove the lug nuts and take off the tire.

3. Inspect and Repair

If a puncture is found, clean the area around the puncture and apply a tire plug according to the kit instructions.
For valve stem issues, replace the valve stem using a valve core tool.
If the tire is damaged beyond repair, consider replacing it with a new tire.

4. Re-install Tire

Place the tire back onto the wheel hub.
Hand-tighten the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs for a Model S).

5. Inflate Tire

Inflate the tire to the recommended pressure, usually found on the driver's door jamb.
Re-check the tire pressure after inflating to ensure it is set correctly.

6. Reset TPMS (if applicable)

If the TPMS light remains on after addressing the tire issue, reset the TPMS by following the vehicle's specific reset procedure (refer to the owner's manual for guidance).
