TPMS Warning After a Tyre Change

A tyre-pressure warning after a tyre change needs a tyre and pressure check before you assume the sensor has failed. The reset process also varies between vehicle systems.

Quick answer

Check the tyre pressures against the vehicle information and inspect the tyres for visible damage or pressure loss. If the warning remains after the vehicle's specified reset or learning process, book a workshop TPMS assessment. Do not ignore a warning that returns after inflation.

Check tyre pressure and condition first

A warning after tyre work can still relate to pressure. Check all four tyres when they are cold, using the vehicle's stated pressure information. Look for a visibly soft tyre, a damaged valve area, a tread puncture or a sidewall problem before blaming the monitoring system.

A new tyre does not rule out a separate pressure issue. A wheel can have an existing valve, rim or sensor concern, and the system may identify a difference before the driver notices it. Start with the tyre condition because it is the safety-critical check.

  • Use the vehicle's tyre-pressure information, not a generic figure
  • Check all tyres and the spare where the vehicle system requires it
  • Do not continue to reset a warning that returns after correct inflation

The reset method depends on the vehicle

Some systems use wheel-mounted sensors. Others compare wheel rotation data and need a reset through the vehicle menu after tyre pressures are corrected. The exact learning or reset procedure depends on the make and model.

Use the handbook for the correct reset process. If the light remains or flashes, the workshop can inspect the tyre and wheel first, then consider the sensor, valve or system programming route where it applies.

Know when a TPMS assessment is the right route

Book TPMS support when tyre pressures are correct, the tyre has been checked and the warning still returns. The workshop can identify the practical next step instead of replacing a sensor based on the dashboard light alone.

Book puncture inspection instead when one tyre continues to lose pressure, a nail or screw is visible in the tread, or the tyre has damage. The monitoring system can alert you to a problem, but it does not decide repairability.

Give the workshop useful information

Tell the team when the warning began, whether it stays on or flashes, and what tyre work has taken place. Include the vehicle registration and any visible tyre or wheel issue. This helps the workshop prepare the right assessment path.

Call before travelling if a tyre is flat, visibly damaged or losing pressure. IQ Tyres provides workshop support in Mitcham rather than mobile or roadside tyre attendance.

Frequently asked questions

Why has my TPMS light come on after new tyres were fitted?

Check tyre pressures and visible tyre condition first. The vehicle may also need its specified reset or learning process, which varies by make and model.

Can I reset the TPMS warning without checking the tyres?

No. The tyre pressure and visible condition should be checked first, because the warning can relate to a genuine pressure or tyre issue.

Does every car have sensors inside the wheels?

No. TPMS systems differ. Some use wheel-mounted sensors and others use vehicle data to identify a pressure-related difference.

When should I book a TPMS service?

Book a TPMS assessment when the warning remains or returns after the tyres and pressures have been checked and the correct vehicle reset process has been followed.
