Modern vehicles increasingly use technology to help drivers understand their vehicle's condition. One useful example is the Tyre Pressure Monitoring System (TPMS), which alerts drivers when tyre pressure falls outside an expected range.
What is TPMS?
TPMS is an electronic system designed to monitor tyre pressure. Depending on the vehicle, it may use sensors installed inside the wheels or estimate pressure changes through wheel-speed information from the anti-lock braking system.
Direct and indirect monitoring
Direct TPMS uses pressure sensors to measure the pressure inside individual tyres. The readings are transmitted to the vehicle's monitoring system.
Indirect TPMS uses information from wheel-speed sensors. An underinflated tyre can rotate differently from a properly inflated tyre, allowing the system to detect a potential pressure problem.
The exact capabilities vary by vehicle model.
Why these systems matter
Incorrect tyre pressure can affect handling, braking behaviour, tyre wear and energy consumption. An alert can prompt a driver to investigate a possible problem before continuing a journey.
However, TPMS does not replace regular tyre inspections. It may not detect every type of damage, and a warning may appear only after pressure has changed significantly.
What should you do when the warning appears?
- Find a safe place to stop if the warning suggests a serious problem.
- Inspect the tyres for visible damage when it is safe.
- Check pressure using a suitable gauge.
- Inflate tyres according to the vehicle manufacturer's recommended settings.
- Seek professional assistance if pressure keeps dropping or damage is visible.
A tyre with a sidewall bulge or serious damage should not be treated as safe simply because the monitoring system shows a normal reading.

Conclusion
TPMS is a useful driver-assistance technology, but it works best alongside regular maintenance and sensible driving practices. Understanding the system helps drivers respond to warnings instead of ignoring them.
