Tires are among the first components to be replaced in any Tesla model. This is due to tire wear from the electric motor’s instantaneous torque. When replacing tires, you will have to service the TPMS sensors.

I used a Tesla Baolong (2012 to 2014), Continental (2014 to 2020) and a proprietary sensor that uses Bluetooth. For 2021, the Model Y starts using a sensor that communicates using Bluetooth protocols. Not much is known about the new system except that the sensors are currently only available through Tesla.
Baolong TPMS will not display pressures on the center display. However, Continental and Bluetooth will display pressure on the driver. Tesla offers a retrofit kit to convert the Baolong system into a Continental system. The procedure includes replacing the unit on the car. Baolong sensors are available on the market, and aftermarket replacements can be programmed to the vehicle.
Like many TPMS systems, the Tesla TPMS has a built-in feature that automatically detects a new set of wheel sensors. TPMS sensors can be reset via the vehicle’s touch screen. The reset function is only possible when the car is in the running position.
Before beginning, adjust tires to the correct cold tire inflation pressure according to the door label and tire size. Before servicing the tires, make sure the system is working.
- Turn on the touch screen.
- From the touch screen, touch Controls > Settings > Service and reset > Tire pressure monitoring > Reset sensors. Reset the sensors based on wheel size.
If a tire pressure warning appears, exit the vehicle, close the trunk and all doors, wait for the touch screen to turn black, re-enter the vehicle and make sure the correct wheel size is selected before touching reset.
- Touch Reset, then touch OK.
- Press and hold one of the scroll wheels and select Vehicle Status to see an overview of TPMS information. When the sensors are unknown, all values will be displayed as “- -“.
Ensure that the vehicle has been stationary for at least 20 minutes before proceeding to the next step.
- Take a road test. Automatic learning will start when the vehicle exceeds 25 mph. When automatic learning is completed, tire pressure information is displayed for all wheels and eliminates any TPMS malfunctions. Note: Auto learning can take up to 20 minutes during a test drive.
Try this procedure again if “Tyre pressure system needs servicing” is displayed after performing the automatic learning. If the warning persists after 5 minutes of driving at 25 mph, further diagnosis may be needed. This can include using a TPMS to verify sensor operation.
Most Tesla models use service kits that have a metal clip-on stem. A new service assembly must be installed each time the tire is removed from the rim. The valve stem nut is a single-use component. Most kits are available in two types of silver and black rims.
There are a variety of 433MHz programmable sensors for Tesla models. There are also direct replacement options.
What is the problem with the foam?
Some original Tesla tires have a layer of foam attached to the inside. This foam is designed to absorb engine or transmission noise. If there is a puncture, you can still fix the tire. You can cut the foam away from the tire area and use a patch. Just replace the foam section with cement glue.
