Due to high fuel prices, all tyre manufactures are rapidly moving towards the energy saving tyre, which in some cases will make a noticeable difference to your pocket.
Without getting too technical, energy saving tyres require less energy to roll. An easy-rolling tyre has lower demands on fuel.
You may have heard of tyres with low rolling resistance. In the past, low rolling resistance tyres meant having a tyre with a very hard rubber compound and stiff sidewalls to reduce friction and flex. While this approach worked moderately well in reducing friction, it made the vehicle very uncomfortable and had very little grip.
Today tyre manufactures use new compounding techniques, such as silica-based compounds giving low rolling resistance without compromising the grip or comfort.
By law all tyres sold in UK must be labelled for the benefit of the consumer. This label grades the tyre on fuel efficiency, wet grip and external rolling noise. For more information on tyre labelling go to http://ec.europa.eu/energy/efficiency/tyres/labelling_en.htm
