Winter Sawdown Roadstone Winguard Winspike 215/55 R17 98T

Roadstone Winguard Winspike is a high -quality abstract created for safe driving in the most stringent weather conditions. Despite the presence of metal spikes, the tire does not produce loud noises and strong vibrations that can be transmitted to the salon through the suspension elements and deliver discomfort to the driver. A modernized tread pattern consisting of pointed edges, guarantees the excellent control of the machine on the road covered with thick ice crust and packed snow.

the new Roadstone Winguard Winspike tire system is fundamentally different from the one that was used in previous generations Winter tires of this brand. They are distributed on the surface of the tread in 12 rows and grouped in such a way as to create maximum pressure on the roadway while driving. Due to the increased pressure, the ice crust on the asphalt is instantly pierced with spikes, so that the wheels do not slip and do not slip on the ice. The tips of the spikes have sharp gear edges. This allows tires to more effectively adapt to the road surface, and the car is faster to gain speed during acceleration, instantly slow down during braking and maintain stability during descent or lifting on roads with a steep slope.

Microscopic particles are included in the rubber mixture high molecular weight polymers and silicon dioxide. They perform different functions - provide additional clutch with ice, give rubber optimal indicators of rolling resistance, reduce wear intensity. To maintain the elasticity of the tire in severe frosts, a special component - silica is added to the compound. This substance makes the rubber more flexible, soft and elastic, not allowing it to harden with a rapid decrease in temperature.
