For summer tyres, wet grip is especially important in terms of safety. It indicates the car's braking abilities on wet roads. A is the best class, while F is the weakest. Classes D and G are not used.
Tyres with excellent wet grip have a shorter braking distance, more stable handling, and better driveability.
The wet grip rating is misleading
The wet grip rating for a tyre does not indicate how suitable the tyre is for the real winter weather. For example the Nordic non-studded winter tyres are tailored for the harsh roads, at times very slippery, and the ice and snow. Non-studded tyres developed for Central European conditions heavily emphasise fast driving, at the expense of grip on ice.
Difference in braking distance equals four car lengths
The label indicates the tyre's braking distance on wet asphalt, from a speed of 80 km/h. For example, the difference between class A and class F in terms of stopping distance can be over 18 metres, or four car lengths. The difference between adjacent categories is about one car length (3 to 6 m).
?? Best and weakest. Classes A to F, braking distance over 18 metres shorter.
?? Adjacent classes. For example: B to C, braking distance shorter by one car length.
Fuel savings and road safety are highly dependent on the driver’s behaviour. Take into account the following issues:??
- Economic driving can significantly reduce fuel consumption
- To optimise road safety and driving comfort, tyre pressure needs to be checked at regular intervals
- If the tyre pressure is too low, the tyre wears out much quicker than usual; it also affects fuel consumption and poses a clear risk in terms of road safety
- A responsible motorist is always aware of the properties and condition of his/her tyres. Only a driver who knows the vehicle and tyres can adjust the speed and safety distance to match the current weather.
