5 Rolling resistance


A rolling tire deforms and dissipates energy. It is one of the 5 resistive forces acting on a vehicle. The energy lost in this way, is expressed as ‘rolling resistance' and is measured by the amount of energy dissipated per unit of distance travelled and per unit of weight carried. Rolling resistance directly impacts fuel consumption and the environment. At lower rolling resistance, the tyre dissipates less energy, contributing less to resistive forces and thereby reducing fuel consumption and CO2 emission.

In the EU Tyre Regulation label, rolling resistance is expressed in grades, ranging from A to G, informing you about the relative fuel efficiency performance level. A is the highest performance tyre in its category; G is currently the least performing.

To indicate the level of rolling resistance of a tyre, Goodyear has developed three logos, helping you to select energy efficient tyres for your vehicle. These logos are applied on the sidewall of tyres featuring the Goodyear's FuelSaving Technology, such as EfficientGrip, DuraGrip or Excellence. In the future, usage of this technology will be further expanded throughout the Goodyear tyre range.
