Research Shows The Majority of Drivers Have Incorrect Tyre Pressures

Kwik Fit has revealed the results of research which shows 69 per cent of cars in the UK are being used with under-inflated tyres, at least 3psi under the manufacturer's recommendation, with just four per cent of motorists are travelling on all four tyres with the correct pressure.

Kwik Fit have revealed that the average under-inflated tyre is down by 18%. The smallest amount of under-inflation can reduce fuel efficiency, with an estimated £993 million wasted every year on excess fuel.

Under-inflated tyres result in poor handling and braking, as well as causing tread damage and the possibly causing blowouts. Kwik Fit's study shows that almost 10% of cars had tyres on the same axle with a difference of 10psi or more.

On average, spare tyres are under-inflated by 18psi, 44% lower than the recommended average pressure of 44psi for a spare.

The study has also shown that some 14% of tyres are over-inflated by 3psi or more, with the average over-inflated tyre being 3.75psi above the recommended figure.

Ian Fraser, chief executive of Kwik Fit said: "Under-inflated tyres not only hit hard pressed motorists in the wallet but can be extremely dangerous, potentially leading to a blow-out. With research showing that many service station tyre gauges are inaccurate, motorists may well feel safer coming to Kwik Fit where their tyre pressure can be checked using calibrated pressure gauges for free by a tyre expert.

"If your tyre won’t hold its pressure, there could be a slow leak in the valve or a puncture. These problems are mostly cheap and easy to fix. For those who are worried about their spare, there’s always nitrogen inflation. Nitrogen molecules are bigger – and indeed drier – than those in normal air, so help keep a tyre at the correct pressure for longer."
