Wet grip
The most important role of a tyre is to provide safety - in all conditions. Wet adhesion or  grip is one of the most important performance characteristics.
grip is one of the most important performance characteristics.
However, higher adhesion and lower rolling resistance are often contradictory objectives that have traditionally required a performance trade-off. Thanks to the new labeling regulation, customers will be able to see and choose for themselves their preferred performances.
The label will display a range of 7 grades where tyres with an “A” provide the highest levels of wet grip and “G” the lowest.
Rating D is not used for passenger cars. Any tyre which does not meet the standard for C grade is categoried as E grade. There is also no G grade for wet grip so the lowest grade is F.
In an emergency situation, a few meters can make all the difference. For a passenger car applying full brakes from 80kph, a set of A-rated tires will stop up to 18 metres shorter than a set of F-rated tires. **
**When measured according to the test methods set out in Regulation EC 1222/2009. Braking distances may vary according to driving conditions and other influencing factors.
Label values shown are for illustrative purposes only. Values for a certain tire line/size may vary.
