BKT Sierra Max. FEATURES AND BENEFITS: Mud terrain traction; Enhanced controllability; Damage resistance; . OVERVIEW: The BKT Sierra Max is a mud terrain, all season tire manufactured for ATVs and UTVs.The tread design enhances the model's off-road performance. This mud terrain tire features a zigzag placement of staggered tread lugs and a high void ratio, which work together to boost the soft, loose and uneven terrain grip. This ensures the tire's performance on such terrains, without allowing the tire to be stuck in deep mud or on loose dirt. The tread's self-cleaning pattern also helps improve the traction. The tread prevents mud and snow from packing into the footprint and blocking the tire's surface contact. This results in a stronger off-road traction and higher levels of driving safety.The tread design's optimal traction and maintained surface contact upgrade the model's handling. The better and closer terrain contact upgrades the tire's steering responsiveness and driving stability significantly. This allows the tire to boost the steering response time and accuracy to the driver's commands, while it also secures the structural stability against the driving pressure during the tire's performance. This combination ensures the driver's full control over the vehicle, offering a secure drive.The Sierra Max protects the tire from off-road hazard which may harm its casing and shorten its service life. The self-cleaning nature of the tread design manages to avoid stone retention. As rocks cannot drill into the tread area, they are unable to harm the tire's casing, offering a safer performance. On the other hand, the durable compound and tire structure work together to guard the tire against punctures, cuts and other off-road damage. The compound also helps prevent the tread's chipping, cracking and tears. The overall result is a longer lasting usability. When it comes to ATV tires, there might be slight visual differences between brands and models even if the tires are of the same size. NOT FOR HIGHWAY USE: This tire model is not DOT-approved for highway use. 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.
