Forceum D850. FEATURES AND BENEFITS: High speed controllability; All weather traction; Reduced road noise levels; . OVERVIEW: The Forceum D850 is a performance and high performance, depending on the speed rating of the specific model, all season tire manufactured for passenger vehicles.The tire ensures first-rate high speed controllability. The special directional tread design features dynamic semi rib blocks and a continuous center rib that maintains the tire's road contact at all times. This upgrades the steering response time and accuracy to the driver's commands, while it stabilizes the structure against the driving pressure affecting the model. The optimal shoulder tread block placement increases the cornering ability and power. The blocks enhance the number of biting edges firmly gripping the road surface during cornering and maneuvering to guarantee a safer performance. The directional tread design evenly distributes the driving pressure to avoid heat build-up during the high speed drive. As a result, the tire is capable of performing to its greatest high speed capability with ease.The tread design and all season tire compound enhance the all weather traction. They keep a firm grip on the road surface in dry, wet and winter weather. The tread design's biting edges and the all season compound's maintained flexibility ensures a secure driving experience in all weather. The zigzag shoulder tread block placement and circumferential grooves disperse water and slush from below the tire's footprint. The increased year round traction and hydroplaning resistance provide a safer drive throughout the year.The D850 offers a quiet drive. The special zigzag shoulder tread block design prevents airwaves from entering the tire's footprint. In this manner, the airwaves don't come into contact with the tread elements and the road and tread pattern noise are not generated. While the tires are in motion, the tread design ensures a quiet and comfortable driving experience. 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.
