What is TPMS?
TPMS stands for Tyre Pressure Monitoring System. Since November 2014, all new cars sold in the EU and UK must be fitted with TPMS as standard. The system monitors tyre pressure in real time and alerts the driver via a dashboard warning light — typically an exclamation mark inside a horseshoe shape — when pressure in one or more tyres drops 25% below the recommended level.
Why Tyre Pressure Matters
Driving on underinflated tyres is one of the leading causes of tyre failure in the UK. It increases rolling resistance (cutting fuel economy by up to 3%), causes rapid tyre wear on the outer edges, generates excess heat (which can cause sidewall failure), and significantly reduces braking and handling performance. A tyre that's 20% underinflated has its lifespan reduced by 20% and poses a real safety risk on Leeds's motorways and dual carriageways.
What to Do When Your TPMS Light Comes On
Don't ignore it. Pull over when safe and check all four tyres visually. If one appears noticeably flatter, you likely have a slow puncture or significant pressure loss. Check pressures at a petrol station or with a home gauge. Correct pressures are found in your vehicle handbook, inside the driver's door jamb, or inside the fuel cap. If pressures are correct but the light stays on, your TPMS sensor may need resetting or replacing.
TPMS Sensor Replacement in Leeds
TPMS sensors contain a battery that typically lasts 5–10 years. When a sensor fails, the light stays permanently on. Leeds Tyre Guys supply and fit replacement TPMS sensors for all vehicle makes and models, and we relearn/reset sensors as part of every tyre fitting. Call 0113 234 5678 for TPMS diagnostics and repair across West Yorkshire.
