Swapping to a set of aftermarket wheels is one of the most common upgrades Australian drivers make — and one of the most common ways the dashboard warning light ends up stuck on. The culprit is almost always the tyre pressure monitoring system (TPMS). This guide explains how TPMS and aftermarket wheels interact, and what you actually need to do.

Is TPMS even mandatory in Australia?

No. Unlike the United States and Europe, Australia does not mandate TPMS on passenger cars. But many vehicles sold here still have a factory system because they’re built to US or European rules, as CHOICE notes in its TPMS buying guide. So whether aftermarket wheels are a problem depends entirely on whether your specific car has a system — and which type. For which models tend to have it, see which Australian models get TPMS as standard.

What’s the difference between direct and indirect TPMS?

This is the single fact that decides whether new wheels are easy or expensive.

	Direct TPMS	Indirect TPMS
How it works	A battery sensor in each wheel measures actual pressure	Uses ABS wheel-speed sensors to detect a tyre spinning faster (deflating)
Hardware in the wheel	Yes — one sensor per wheel	None
Shows actual pressure?	Often yes	No — warning light only
New wheels need…	Sensors transferred or bought, then a relearn	Just a reset/re-initialisation

With indirect TPMS there is no hardware in the wheel, so aftermarket wheels cost you nothing extra — you re-initialise the system through the dash menu after the swap. With direct TPMS, every wheel needs a working sensor. Our broader explainer, how tyre pressure monitoring systems work and when they lie, covers the quirks of both.

Should you transfer your old sensors or buy new?

If your existing sensors are healthy and physically compatible with the new wheels, a tyre shop can transfer them into the new set when the tyres are fitted — the cheapest option. Transfer isn’t always possible, though: sensor batteries last only several years and can’t be replaced on their own, the valve/seal service kit should be renewed each time a sensor is disturbed, and some sensors don’t suit every wheel’s valve hole. If a sensor is near end of life or won’t fit, you’re buying new.

What are universal and programmable sensors?

Aftermarket universal, configurable and programmable sensors are the usual replacement. A tool writes the correct vehicle protocol — or clones your old sensor’s ID — into a blank sensor so it behaves like the factory part at a lower cost than OE. This is standard practice at any TPMS-equipped tyre shop and is often cheaper than four genuine sensors.

What is a TPMS relearn and will you need one?

A relearn teaches the car which sensor is in which corner. On a direct system you need one whenever sensors are replaced, wheels are swapped or tyres are rotated. Tire Review’s TPMS reset guide describes the three methods:

• Auto relearn: no tool — inflate all tyres correctly and drive for a set period (for example, around 20 minutes) until the system relearns.
• Stationary relearn: a TPMS activation or scan tool puts the car in learn mode and triggers each sensor in sequence.
• OBD relearn: a diagnostic tool reads the sensor IDs and writes them to the car through the OBD port — common on many Asian and some European cars.

Procedures vary by make and model, so the fitter checks the correct method for your car. The reset after new tyres is covered further in TPMS reset procedures after fitting new tyres.

What does this mean when buying aftermarket wheels?

Before you buy, find out whether your car has direct or indirect TPMS. For direct systems, budget for either transferring your sensors (plus service kits) or four replacement sensors and a relearn. Factor it into the overall fitment the way you would brake clearance or offset — it’s part of a correct aftermarket setup, alongside the checks in inspecting second-hand wheels and the general trade-offs in alloy vs steel wheels.

Frequently asked questions

Will the TPMS light stay on if I fit aftermarket wheels without sensors?

On a direct system, yes — with no sensors the car can’t read pressures and the warning light stays lit, which can also fail a roadworthy check if the system is deemed non-functional. On an indirect system there are no sensors to miss, so a reset clears it.

Can I just move my old TPMS sensors to the new wheels?

Often yes, if the sensors are healthy and fit the new wheels’ valve holes. The shop renews the service kit and performs a relearn. If a sensor’s battery is near end of life, replace it rather than transfer it.

How long do TPMS sensor batteries last?

As a guide, several years — the battery is sealed in the sensor and can’t be replaced on its own, so an older sensor is often replaced rather than reused when wheels are changed.

Do I need a relearn after every tyre rotation?

On many direct systems, yes, because the sensor moves to a new corner. Some cars relearn automatically as you drive; others need a tool. Check your specific model’s procedure.

Bottom line: Direct TPMS means every aftermarket wheel needs a working sensor and a relearn; indirect TPMS just needs a reset. Find out which system your car has before you buy wheels, and budget for sensors and a relearn if it’s direct.
