The fuel cost of under-inflated tyres

This is the advice of Kwik Fit, which says over £650,000 worth of fuel every day is wasted by motorists because of under-inflated tyres.

Under-inflated tyres make the car less efficient by up to five per cent because it requires more engine power. Each car has a different optimum tyre pressure as outlined in the manufacturer’s book.

However, motorists are also being warned against over-inflating tyres because it could cause loss of grip and extra wear-and-tear on the tyre itself.

Roger Griggs, communications director at Kwik Fit, says: “Rather than panic-buying excess fuel, motorists could consider finding ways to improve their fuel efficiency. This can be achieved by making relatively simple adjustments motorists can drive further on one tank and shouldn’t really need to store extra fuel in jerrycans.”

UK drivers are increasingly turning to fuel-efficient cars in the wake of confirmation a 3p per litre increase in fuel duty will be introduced as planned in August.

The news has seen an increase in interest at dealerships for fuel-efficient cars and has prompted Ford to reduce CO2 emissions and improve fuel economy in its most efficient car, the Ford Fiesta Econetic.

Other manufacturers such as Vauxhall, Seat and Citroen also offer ‘eco-signature’ vehicles designed to offer lower running costs than ever before.

Meanwhile, several groups have criticised the government for creating a panic out of potential fuel strikes, with drivers queuing for fuel across the country.
