Why Correct Tyre Pressure Matters for UK Drivers
Running on incorrect tyre pressure is one of the most common — and most preventable — causes of poor fuel economy, premature tyre wear and dangerous handling. Checking your tyre pressure takes two minutes and should be done at least once a month and before any long journey.
Where to Find the Correct Tyre Pressure
Your vehicle's correct tyre pressure is specific to your car and tyre size. You will find it in one or more of these locations:
- The driver's door jamb (a sticker on the door frame or sill)
- Inside the fuel filler cap
- Your vehicle owner's handbook
Note that the correct pressure may differ between front and rear tyres, and manufacturers often recommend higher pressures when carrying heavy loads or towing.
Under-Inflation: The Most Common Problem
Under-inflated tyres are the number one cause of tyre failures in the UK. A tyre that is 20% below its recommended pressure can increase fuel consumption by 2% and dramatically increase heat build-up in the tyre, which accelerates wear and can lead to a sudden tyre blowout at motorway speeds.
Over-Inflation: Less Common but Just as Dangerous
Over-inflated tyres are harder, which reduces the contact patch with the road surface. This decreases grip, particularly in wet conditions, increases braking distances and makes the ride harsher. Centre tread wear — where the middle of the tyre wears faster than the edges — is a classic sign of over-inflation.
TPMS Warning Light
Most vehicles made after 2014 are fitted with a Tyre Pressure Monitoring System (TPMS). If the horseshoe warning light appears on your dashboard, check your tyre pressures immediately. If you need a TPMS sensor replaced or recalibrated, Saltire Mobile Tyres offers this service as part of our mobile fitting service across Yorkshire and Scotland.
