Tyre pressure is one of the most frequently overlooked aspects of vehicle maintenance, yet it has a direct impact on safety, fuel economy, tyre lifespan, and driving comfort. Getting your tyre pressure right costs nothing and takes just a few minutes, but many UK drivers go months without checking their tyres at all.
How to Find the Correct Tyre Pressure for Your Car
Every vehicle has a manufacturer-specified tyre pressure, usually expressed in PSI (pounds per square inch) or bar. You'll find this information inside the driver's door sill, inside the fuel filler cap, or in your vehicle handbook. Note that the recommended pressure is often different for front and rear tyres, and may change depending on the load you're carrying — many manufacturers list a higher pressure for a fully loaded vehicle.
What Happens When Tyre Pressure Is Wrong?
Under-inflated tyres flex more than they should, generating excess heat and causing rapid wear on the outer edges of the tread. They also increase rolling resistance, which pushes your fuel consumption up noticeably. Over-inflated tyres ride harshly, reduce the tyre's contact area with the road, and cause accelerated wear in the centre of the tread. Both conditions affect handling and extend stopping distances — especially in wet weather conditions common across the UK.
How Often Should You Check Tyre Pressure?
The RAC and tyre safety organisations recommend checking your tyre pressure at least once a month and before any long journey. Always check pressures when tyres are cold — pressure rises as tyres warm up during driving, so checking them straight after a journey will give you a misleading reading. Most petrol stations have air pumps, and a basic tyre pressure gauge for home use costs just a few pounds.
