Improving driving safety in all winter conditions.
The optimised Nordic Matrix compound consists of silica, oil and carbon black to provide a higher overall performance level. The silica improves performance on wet surfaces, the added oil makes for better handling in winter conditions, while the carbon black facilitates a superb mileage. All in all, the tyre's new matrix is especially well optimised for Nordic roads.
The tyre's optimised directional pattern improves handling during slushplaning and aquaplaning, since this enables water and slush to be displaced more effectively out of the pattern.
The sipes around the pattern interlock in the left and right driving directions to provide a better grip. The VanContact™ Viking is also equipped with snow catchers within its grooves: loose snow from the road's surface gets collected inside these grooves. This improves the snow-snow traction, which leads to enhanced handling and a better braking performance in all driving situations on snow and ice.
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.
