BKT AT-109. FEATURES AND BENEFITS: All terrain traction; Enhanced controllability; Improved durability; . OVERVIEW: The BKT AT-109 is an all terrain, all season tire manufactured for ATVs and UTVs.The tire promotes great all terrain traction. The knobbed tread pattern increases the soft, loose and uneven terrain gripping capability. The sidewall and tread area patterns improve the grip the tire has on the terrain surface during its performance, ensuring a secure driving experience. The tread's high void ratio manages to keep the footprint clean of mud and snow and eject rocks from the footprint, preventing stone retention and maintaining a constant surface contact. The better traction and self-cleaning ability boost the off-road terrain driving safety.The optimal tread design allows the tire to improve its controllability. The knobbed pattern closely follows the terrain surface at all times, to enhance the steering responsiveness and the driving stability. This enables the tire to increase the steering response time and accuracy to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. This guarantees the tire's exceptional controllability and maneuvering capability on various terrain surface conditions.The AT-109 was designed with a reinforced internal structure. The stronger construction maintains the tire's ideal shape under the load and driving pressure affecting the model. As the tire does not deform under the pressure, it is able to perform at its greatest capability with ease, guaranteeing a safer driving experience. This specific tire model features a BIASED ply construction. 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.
