Tesla uses direct TPMS with live pressures shown on the touchscreen — inflate to the placard and the readings update on the move; there is no manual reset button.
Why the Tesla tyre pressure light is on
Every Tesla wheel has a Bluetooth or 433MHz sensor reporting live pressure, and the car shows the actual PSI for each corner on screen. The alert means a genuine drop below the placard value, a sensor that has stopped transmitting, or wheels swapped over without the new sensors being learned by the car.
Tesla tyre pressure light reset — step by step
- Open the touchscreen and note the live pressure for each corner — Controls → Service, or the tyre pressure card on Model 3/Y.
- Set all four tyres cold to the placard pressure on the driver's door pillar (commonly 42 PSI on Model 3 and Model Y — check your own placard).
- There is no manual reset: the readings refresh on their own.
- Drive above 15–20mph for around 10 minutes so every sensor transmits a fresh reading.
- If you have fitted a new set of wheels, drive for around 20 minutes so the car can learn the new sensor IDs automatically.
Models covered
Model 3, Model Y, Model S, Model X
If the light won't go off
If one corner shows dashes rather than a number, that sensor isn't transmitting and needs replacing. Bear in mind Tesla placard pressures are high (often 42 PSI cold) — a forecourt machine set to 36 PSI will trigger the alert on a perfectly healthy car.
What it costs
No reset cost. Sensor replacement is typically £50–£90 per wheel fitted at an independent that can program Tesla sensors; Tesla Service is usually £100–£150 per wheel.
Bob's workshop tip
Teslas are heavy and run high pressures, so a small drop shows up fast. Check them cold once a month — and remember the placard figure is a cold figure, so topping up after a motorway run will leave you under-inflated the next morning.

Why is my Tesla tyre pressure light on?
Every Tesla wheel has a Bluetooth or 433MHz sensor reporting live pressure, and the car shows the actual PSI for each corner on screen.

How do I reset the tyre pressure light on a Tesla?

How much does it cost to fix a Tesla TPMS fault?
No reset cost. Sensor replacement is typically £50–£90 per wheel fitted at an independent that can program Tesla sensors; Tesla Service is usually £100–£150 per wheel.
What Bob keeps in the boot
A pump puts air back in, but it will not seal the hole. For a nail or a screw in the tread, the repair itself is the Emergency Puncture Repair Kit — £9.99 with free UK delivery: rubber rope plugs, reamer, T-handle tool and rubber solution, posted from the workshop in Birnam, Dunkeld. If you would rather not take a wheel off at the roadside, the quick-fix tyre repair spray is the no-tools option. Keeping the pressures right in the first place is covered in tyre pressures by registration and resetting the tyre pressure warning light, and the pump itself in Bob's electric tyre pump picks.
Be straight about what a plug is: a get-you-home repair for small punctures in the central three-quarters of the tread. Never plug sidewall or shoulder damage, drive gently afterwards, and have the tyre inspected or replaced by a tyre specialist as soon as you can.
