Duro DI-K658. FEATURES AND BENEFITS: Enhanced controllability; All terrain traction; Upgraded load durability; . OVERVIEW: The Duro DI-K658 is an all terrain, all season tire manufactured for ATVs and UTVs.The tire manages to optimize the surface contact on both on- and off-road terrain surfaces. The ideal knob placement upgrades the surface contact at all times, enhancing the steering responsiveness and driving stability. A faster and more precise steering response to the driver's instructions is assured and it effectively secures the structural stability against the driving pressure. As a result, the better controllability guarantees the driver's better control over the vehicle at all times.Better all terrain traction is promoted as well with the ideal knob placement. These tread elements and the high void ratio enable the tire to increase the soft, loose, and uneven terrain traction. These tread elements ensure the tire's exceptional forward motion on versatile terrains, upgrading the deep mud and loose dirt terrain performance. The tread's void ratio does not allow the tire to block the surface contact by mud or snow. Stone retention is also avoided since rocks do not drill into the tread area. This enables the tire's exceptional performance capability and off-road terrain driving safety levels.The DI-K658 increases the load durability as well. The reinforced internal structure does not allow the tire to deform under the load and driving pressure. Since the tire maintains its ideal tire shape, it is able to securely carry and withstand heavy loads with ease. This upgrades the tire's optimal performance. 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.
