The Maximum Traction Silica Compound ensures excellent wet grip and therefore improves braking performance significantly. Additionally the WinterContact™ TS 860 stays flexible at any winter weather and transfers the braking forces safely onto wet, icy and snow-covered roads.
This new sipe channel system helps to constantly dewater the tires' contact surface for an improved braking performance on icy and frost-covered roads. This special drainage eliminates the danger of deteriorated braking performance caused by melting water, which supports faster braking.
The new WinterContact™ TS 860 strenghtens the interlocking of the tire with snow-covered roads via the new Snow Curve+ technology. By compressing the snow at more than 1000 spots all over the profile, it provides a better overall grip, especially while cornering.
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.
