Fuel Efficiency / Rolling Resistance: E Rolling resistance has a direct impact on fuel consumption. A tyre's rolling resistance score ranges from A to E.
Wet Grip / Braking Performance: C A tyre's wet grip capacity is expressed in Grades from A to E. The difference in braking distances between each grade is roughly 3m - an average car length.
Noise Emission / Exterior Noise: 73dBs, B rating The exterior noise grade of a tyre is expressed in decibels and accompanied by an external rolling noise rating - ranging from A (least exterior noise) to C (highest level of noise).
