The energy lost when a tyre is in motion is known as 'rolling resistance'. This has a direct impact on fuel consumption. A tyre's rolling resistance score ranges from A to G. Over the life of the tyre, fitting an A rated tyre could save you up to 6 litres of fuel when compared to a G rated tyre.
A tyre's wet grip capacity is expressed in Grades from A to G. The difference in braking distances between each grade is roughly 3m - an average car length. This makes average stopping distance between an A and G rated tyre 18m. That's 4 car lengths.
The exterior noise grade of a tyre is expressed in decibels - accompanied by one, two or three sound waves, with one wave being the best noise level performance. To achieve the best grade, a tyre’s noise level must be at least 3dB under the legal limit set by the EU.
- Circumferentially stiff tread ribsensures excellent braking performance as well as precise handling and directional stability.
- "Grip" edges and incisions in the outside shoulder provide for additional traction, especially in wet curves.
- The optimal arrangement of wide circumferential grooves in the middle of the tread and pronounced lateral grooves on the inside shoulder ensure very good expulsion of water. Optimum siping offers maximum grip on the wet roads and a comfortable ride.
