At slush hydroplaning, the tire at much as when hydroplaning on wet roads swim lower speeds: they lose the contact with the ground in contrast to hydroplaning, already at 30 km/h on slush the occurs only in about 80 to 90 km/h, the tests of Nokian – prove frightening. Without contact with the tyre with the road, the car can no longer steer, and the braking distance is too long. Slush is the risk of deadly accidents 4.9 times higher than on dry roads, 2008 resulted in an investigation of the Tampere University of technology. Through intensive testing of environmentally friendly premium winter tire optimized Nokian WRG2 for strong protection of slush aquaplaning in the milder German winter, Finnish experts. Also, the slush specialist also still strong saves fuel by lower rolling resistance. For 15 years, performs the Nokian Tyres slush tests, is considered a pioneer in, and today has precise test methods for repeatable measurements for comparing different tire models.

As the sole tire manufacturer, the specialist has a unique test track, where the effects are tested by slush aquaplaning both longitudinal as well as transverse under controlled test conditions. Its engineers have a patented Testing methodology developed, which is recognized by international tire experts. Slush aquaplaning is more dangerous than aquaplaning for the following reasons: the water depth on normal roads is rarely more than 10 millimeters, but slush can be up to 40 millimeters namely on the lanes much thicker and between the lanes up to 100 mm. Slush has a higher viscosity than water is so viscous, therefore slush can be easily derived by the profile grooves like water. The risk of going on slush. When overtaking, one must change the lane and drive it through the slush wall between the lanes. Then the driver turn again on the right track and once again goes through a slush-wall.
