Thanks to the special construction of the traction sipes and the new designed snow grooves the interlocking with the snow significantly raises the traction and handling comfort on snow covered roads.
The blocks of the rib are only separated through thin lateral grooves which form a stiff rib due to the forces while braking. This leads to shorter braking distance espacially for sporty driving in wintry conditions.
Wider and bigger blocks on the outside shoulder increase the contact area which results in larger footprint for maximum control and steering precision while cornering on dry wintry roads.
Due to its combination of innovative compound, profile and construction the WinterContact™ TS 860 S efficiently reduces the rolling resistance for higher fuel saving – without compromising the safety.
Secure grip in wet conditions is crucial for safe driving. Performance is graded into classes, A to G (although D and G are not currently used). The stopping distance between a class A tire and a class F tire can be as much as 18 metres.
Reduced rolling resistance saves fuel and cuts CO2 emissions. Class A tires deliver the best fuel efficiency, with each subsequent class through to G increasing fuel consumption by between 0.42 and 0.56 mpg for a car which does 36 mpg.
This is the external noise made by the tire and is measured in decibels. The more filled bars shown on the label, the louder the tires.
