Rolling resistance is a term used to describe the energy generated by the friction of a tyre rolling over a road surface.
Many factors can affect the amount of rolling resistance generated by a tyre and these include tyre inflation pressure, tread compound, tread design and temperature, to mention just a few.
Many tyre manufacturers market tyres specifically designed to be of a low rolling resistance and these can be recognised by terms such as “Energy” or “Fuel Saver”. These tyres are usually manufactured with a higher degree of silica built into the compound.
Silica in a tyre compound allows the tyre’s grip performance to remain high, particularly in wet conditions, whilst rolling resistance is improved.
