Vitour Polar Bear W1. FEATURES AND BENEFITS: Winter weather traction; Enhanced controllability; Upgraded comfort levels; . OVERVIEW: The Vitour Polar Bear W1 is a touring, winter tire manufactured for passenger vehicles and SUVs.The tire offers excellent winter weather traction. The directional tread pattern and the winter weather compound upgrade the ice and snow-covered road gripping ability. The winter compound keeps its pliability in colder temperatures, while the tread elements' high-density siping pattern boosts the grip the tire has on the road surface. The circumferential and angled lateral grooves prevent hydroplaning. They disperse water and slush from below the tire's footprint, enhancing the winter weather driving safety.The model's tread enhances its controllability. The continuous center rib's constant road contact boosts the steering responsiveness and the driving stability. The increased road contact upgrades the steering response time and precision, while it stabilizes the structure against the driving pressure along the tread area. The shoulder tread block pattern improves the cornering ability and power. These blocks increase the number of biting edges gripping the road surface, which upgrades the maneuvering capability. The high siping density creates friction between the road and the tire, even when driving on ice and snow-covered surfaces, which increases the braking ability. This friction helps shorten the braking distance to guarantee a safer performance.The Polar Bear W1 promotes a comfortable drive. The directional tread's close road contact enables the tire to absorb the shock of driving. In this manner, the tire decreases the road vibrations felt in the vehicle's cabin while the tires are in motion. This results in a comfortable and enjoyable driving experience in all winter weather. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
