UK drivers could improve their fuel efficiency by around six per cent by fitting so-called eco tyres, a new report has shown.
Consumer champion Which? conducted a study of a variety of different compounds to determine which tyres offered the best fuel economy.
The Pirelli Cinturato P7s and the Hankook Kinergy Eco K425 were found to be the leading tyres, ahead of rival compounds from Continental, Goodyear, Bridgestone and Turanza.
Researchers found that a car which returns 40 miles per gallon (mpg) fitted with either the Pirelli or the Hankook tyres would offer an extra 2.4mpg compared to the worst tyre in the test for rolling resistance – the Nexen N800.
With fuel and diesel prices now at records highs, the tyres could save drivers around £50 a year, Which? estimated.
Motorists can also improve their fuel efficiency by ensuring their tyres are the optimum pressure, with a previous Which? test finding that fuel consumption can rise by around three per cent when tyre pressure is dropped by 15PSI, or one bar.
