Falken BI850. FEATURES AND BENEFITS: All weather traction; Lengthened tread life; Self-cleaning capability; . OVERVIEW: The Falken BI850 is a highway terrain, all season tire manufactured for commercial vehicles. It was made to be mounted on the vehicle's drive axle.The tire promotes great all weather traction. The symmetric tread features an optimized tread block pattern and open shoulder design that increase the tire's grip on the road surface in dry, wet and winter weather. This allows the tire to boost the model's performing capability on versatile vehicle applications. The tread elements keep the tire's road contact to upgrade the tire's traction and driving safety. The tread's zigzag circumferential grooves help prevent hydroplaning. They disperse water and slush from below the tire's footprint and further increase the wet and winter weather performance.The model's tread design helps keep the footprint clean at all times. The special zigzag circumferential grooves and the stone ejecting knobs on the groove floor increase the model's stone eliminating ability. They eject rocks stuck between the tread elements to maintain a clean footprint at all times. In this manner, the tire's casing is not damaged by stone retention, which causes rocks to drill into the tread area. The constantly clean footprint offers a secure performance and great damage resistance.The BI850 was manufactured with a wider footprint and an optimal tread pattern. These tread elements manage to lengthen the tread life and the tire's usability. The tread design's improved road contact avoids irregular tread wear formations along the tread area by evenly distributing the driving pressure along the tread area. The equal distribution of the driving force upgrades the tire's usability and extends its service life. 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.
