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.

The weight of your car and your personal driving style also have big influence. Energy effective – “ecological” – driving could considerably reduce fuel consumption.
