FUEL EFFICIENCY/ROLLING RESISTANCE
Category D is not used for passenger cars.
= lowest category of fuel consumptionG (red)
= highest category of fuel consumptionA (green)
Fuel efficiency is assessed by A to G color scale.
20% of the fuel consumption of your car dues to the tyre. Choosing a tyre of a higher class of fuel efficiency will provide you more mileage per tank and less CO2 emissions.
For optimum fuel economy you should take care of the proper inflation. Underinflation of the tyres increases rolling resistance and affects the wet grip. The weight of your car and your personal driving style also have big influence. Energy effective – “ecological” – driving could considerably reduce fuel consumption.
