New innovations

Slush Blower – Safety in slushy conditions

Slush Blower

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.

3D self-locking siping – Precise driving response

3d Self-locking

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.

Dry Touch Suction Sipe – Maximised wet grip

Dry touch

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.

Did You Know

ERA (Electric Race About) built by students of Helsinki Metropolia University of Applied Sciences is an electric car registered for on-road use. Its energy consumption is minimal: only 14.5 kWh, equal to 1.6 litres of fuel per one hundred kilometres, and it has no CO2 emissions at all. The acceleration of this lightly rolling car is supported by the Nokian Z G2 tyres designed for high speeds.

The car accelerates from zero to one hundred km/h in six seconds, and its top speed is 244 km/h. This full-blooded sports car started its career in electric car rally racing very successfully: it achieved second place in the Automotive X-prize 2010 in the USA and won the Michelin Bibendum Challenge 2011 race in Germany. Tyres play an important role in electric cars, because they consume a significant part of the car’s energy. The lower the tyres’ rolling resistance, the longer the electric car’s operating range. One of the greatest challenges in tyre development is the ability to combine a low rolling resistance with the tyre’s safety features.
