Affected Component

Suspension

Estimated Time

30 minutes to 2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface and securely supported when using a jack.
•Always wear safety glasses when working with tires and inflators.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Decreased handling or stability while driving
•Uneven tire wear observed during inspection
•Increased road noise or vibration while driving
•Reduced fuel efficiency (electric range in this case)

Diagnostic Steps

1
Use the Tesla touchscreen to check the current tire pressures for all four tires.
2
Inspect each tire visually for any signs of damage, punctures, or embedded objects.
3
Verify that the tire pressure readings match the recommended PSI found on the driver’s side door jamb sticker.
4
Check for any recent changes in temperature, as cold weather can affect tire pressure.
5
Inspect the tire valve stems for leaks or damage.
6
Use a portable tire pressure gauge to confirm the readings of each tire.

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.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Tire pressure gauge
•Air compressor or portable tire inflator
•Socket set
•Jack and jack stands

Parts Required

•Replacement tires

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor or portable tire inflator, and possibly a jack if tire replacement is required.
Ensure the vehicle is parked on a flat surface and the tires are cool before measuring pressure.

2. Inflate Tires

Sub-steps:
1. Identify the tire(s) that are underinflated based on diagnostic steps.
2. Remove the valve cap from the tire's valve stem.
3. Use the air compressor to inflate the tire(s) to the recommended PSI, which can be found on the driver’s side door jamb.
4. Recheck the tire pressure with the tire pressure gauge after inflating.
5. Replace the valve cap securely.

3. Repair or Replace Damaged Tires (if applicable)

Sub-steps:
1. If any tire shows visible damage or punctures, assess whether it can be repaired or needs replacement.
2. If replacing, use a jack to lift the vehicle at the jacking points.
3. Remove lug nuts with a socket set and take off the damaged tire.
4. Install the new or repaired tire, ensuring it is properly aligned with the wheel hub.
5. Hand-tighten the lug nuts and then torque them to the manufacturer’s specifications (usually around 80-100 ft-lbs).
6. Lower the vehicle and perform a final check on lug nut torque.
