TPMS Reset Procedures After Fitting New Tyres
You pick up the car after a fresh set of tyres and the tyre pressure warning light is glowing on the dash. Nothing is actually flat — the pressures are fine. What has happened is that the tyre pressure monitoring system (TPMS) has lost track of its sensors and needs resetting. This guide explains why it happens, the difference between the two system types, and exactly how each is reset.
Why does the TPMS light stay on after new tyres?
A TPMS light behaves in two distinct ways, and telling them apart is the first step:
- Solid light: after a normal start the light shows for a few seconds, then goes out. If it stays on solid, the system thinks a tyre is low — typically 25% or more below the recommended pressure — or it has simply lost its sensor “learn” after the tyres came off.
- Flashing for a minute or two, then solid: this signals a TPMS malfunction, not just low pressure. Common causes are a dead sensor battery, a damaged or corroded valve, or a relearn that was never completed.
During a tyre change the wheels are removed and the sensors are disturbed, so a relearn is a normal part of the job. If your pressures are all correct and the light persists, see our companion guide to why your tyre pressure light comes on in cold weather — a cold snap can trip it for an entirely innocent reason.
Direct vs indirect TPMS: which do you have?
Resetting depends on which type your car uses, so identify it first. For a deeper explainer, our hub on how tyre pressure monitoring systems work covers both in detail.
| Direct TPMS | Indirect TPMS | |
|---|---|---|
| How it measures | A battery sensor inside each wheel reports actual pressure | Uses the ABS wheel-speed sensors to spot a tyre rolling at a different rate |
| Can show real psi? | Yes, on many cars | No — warning light only |
| Reset method | Auto, stationary or OBD relearn | Usually a dash/menu “reset” button after inflating |
| Affected by rotation/new tyres | Needs a relearn | Needs a re-initialise so it stores the new baseline |
How do you reset an indirect TPMS?
Indirect systems are the simpler of the two. Because there are no sensors to identify, you just give the system a fresh reference point:
- Set all four tyres to the correct placard pressure, cold. (Not sure which figure to use? See placard pressure vs sidewall maximum.)
- Find the TPMS reset button or dash-menu option (check the owner’s manual for its location).
- Hold or select “reset” until it confirms, then drive for a period so the system relearns the normal rolling speeds.
How do you reset a direct TPMS?
Direct systems need the car to re-learn which sensor ID belongs to which corner. Industry data shows the three methods are used in roughly equal measure across modern makes, so your car will use one of them (some combine two):
1. Auto-relearn
The simplest: inflate all tyres correctly, then drive. The system identifies the sensors on its own after a set period — often around 20 minutes of driving. No tool required. Many late-model cars use this.
2. Stationary relearn
Done parked, with a TPMS activation tool. You put the car into “learn mode” via a sequence of ignition cycles and brake-pedal presses (the exact steps vary by make), then trigger each sensor in turn — usually front-left, front-right, rear-right, rear-left — with a horn chirp confirming each one.
3. OBD relearn
A TPMS diagnostic tool reads each sensor’s ID, plugs into the OBD-II port under the dash, and writes the new IDs straight to the car’s computer. A short drive finishes the process. This is increasingly the workshop standard because the same procedure works across many makes.
For most Australian owners the practical point is this: a tyre shop with the right tool does the relearn as part of the fit. If you buy tyres online and fit them yourself, confirm which method your car needs before you start.
What if the light still won’t go off?
If a correct relearn doesn’t clear it, suspect hardware. Direct-system sensors run on a sealed battery that lasts several years, and once it dies the sensor must be replaced, then the relearn repeated. Corroded or cracked valve stems also leak and trip the light. If you have recently changed to aftermarket rims, the sensors may not have been transferred or may be incompatible — our guide to TPMS sensors and aftermarket wheels covers that trap. Whether every Australian car is even required to keep a working TPMS is a separate question — see which Australian models get TPMS as standard.
Bottom line: A TPMS light after new tyres is almost always a missed relearn, not a fault. Indirect systems reset with a button and a drive; direct systems need an auto, stationary or OBD relearn. Set pressures correctly first, complete the right relearn for your car, and if the light survives all that, you are looking at a dead sensor or damaged valve rather than a flat tyre.
Frequently asked questions
Can I reset the TPMS myself without a tool?
If your car uses auto-relearn or has a dash reset button, yes — inflate to placard and follow the manual. If it needs a stationary or OBD relearn, you will need a TPMS tool, which is why most people leave it to the fitter.
Will the light clear on its own if I just keep driving?
On auto-relearn cars, often yes, after a short drive. On stationary- or OBD-relearn cars it will not, because the system cannot identify the sensors without being told to learn them.
Do I need new sensors every time I buy tyres?
No. Sensors are reused across tyre changes and only need replacing when the battery dies (after several years) or a valve is damaged. A good fitter will check them during the change.
Does fitting a space-saver spare upset the TPMS?
A space-saver without a sensor may trigger the warning, which is expected. Reset once the normal wheel is back on. Remember the spare runs a different pressure — see spare tyre pressure.
