Slush is an even more dangerous element for drivers than ice or aquaplaning. The slanting, staggered front edge of the block enhances wet and ice grip. This new innovation is called Slush Blower, because it actually blows water and slush away from the grooves of Nokian WR D3 tyres and thus efficiently prevents slush planing and aquaplaning.
The 3D Lock Sipe featured on the WR A3 locks the outer shoulder area’s blocks together during contact with the road, which makes the structure sturdier and enhances the tyre’s driving response. The blocks cannot move when driving; instead, they support each other. This reduces unnecessary sipe movement, which enhances the tyre’s resistance against wear and tear even in poor road conditions.
The unique suction sipe effectively sucks the water out from between the tyre and the road and routes it to the main grooves of the tyre. This allows the Hakka Blue to achieve maximum contact on the road and establish a firm grip on the dryer road surface. The sipe shape ensures that the firm tyre has excellent wet grip, even when worn. The sipe is larger at the bottom, which means that as the tyre wears, the groove volume increases.
