Tyre pressure sensors, or TPMS – why they matter and what every driver should know
More and more cars come with factory-fitted tyre pressure sensors, or TPMS (Tire Pressure Monitoring System). Many drivers only notice them when a warning light comes on in the dashboard, or when an error message appears after a tyre change. We explain in plain language how tyre pressure sensors work, why they matter and what to keep in mind when changing tyres.
What is a tyre pressure sensor and why do you need it?
The job of a tyre pressure sensor is to constantly monitor the pressure inside the tyres and alert the driver when it drops dangerously low. Correctly inflated tyres provide:
- better handling and safety
- a shorter braking distance
- lower fuel consumption
- a longer tyre life
That is why working tyre pressure sensors are just as important as a quality, reliable tyre change.
Two different TPMS systems
Cars mainly use two types of system.
Direct TPMS: each rim has its own separate sensor that measures the actual tyre pressure and temperature. This is an accurate solution, but after a tyre change it often needs to be set up or the sensors re-learned.
Indirect TPMS: the system uses the car's ABS data and estimates the pressure based on the wheels' rotation speed. There are no separate sensors in the rims, but after a tyre change the system needs to be reset again from the car's menu.
Why does the tyre pressure light come on after a tyre change?
Very often people come to the workshop worried that the TPMS warning light started glowing after a tyre change. There can be several reasons:
- the sensors need to be reprogrammed
- the pressure has been set incorrectly
- the sensor battery is running low
- the sensor was damaged when it was removed from the rim
A professional and fast tyre change always includes a TPMS check as well, so that the customer does not have to deal with error messages later.
How long does a tyre pressure sensor last?
Most sensors have a life of 4–7 years, because they contain a non-replaceable battery. When the battery runs out, the sensor has to be replaced. With us you can get:
- sensor checks and diagnostics
- installation of new TPMS sensors
- programming to suit your car
- a seasonal tyre change together with sensor servicing
We carry out all work affordably and reliably, using quality equipment.
What should a driver keep an eye on themselves?
- Check the tyre pressure at least once a month.
- Do not ignore the TPMS warning light.
- After a tyre change, make sure the system has been reset.
- If a sensor is not working, have it inspected at the first opportunity.
The correct tyre pressure is one of the simplest ways to keep your car safe and your costs under control.
