Hi-Run SU18. FEATURES AND BENEFITS: Enhanced durability; Mud terrain traction; Self-cleaning capability; . OVERVIEW: The Hi-Run SU18 is a mud terrain, all season tire manufactured for ATVs and UTVs.The tire offers excellent off-road traction. The tread pattern features a high void ratio and a V-shaped tread lug placement all around the tire's surface. In this manner, the tread design manages to improve the soft and loose terrain gripping ability, especially on muddy terrain surfaces. The tread design ensures the tire's forward motion on loose and soft terrain conditions and promotes a safer off-road performance as it prevents the tire from being stuck on the terrain surface. The tire's higher flotation also ensures a secure off-road performance and better controllability on such terrains.The tread pattern design guarantees a clean footprint at all times. The high void ratio and V-shaped lug design disperse mud and snow and eject rocks from between the tread elements. This prevents mud and snow from blocking the tire from its contact with the road surface, which enables the tire's constant terrain gripping ability. Stone retention is also resisted in this manner, as the rocks are eliminated from the footprint. As a result, the tire's traction and performing capability are guaranteed at all times, while it increases the driving safety significantly.The SU18 has exceptional durability. The reinforced internal structure enhances the tire's optimal shape under the driving and load pressure affecting it, while also actively preventing off-road damage from harming the tire. The optimal tire shape and stronger construction enhances the tire's load carrying and withstanding capability. The prevention of off-road damage promotes a safer off-road driving capability and it prevents the terrain surface conditions from shortening the tire's lifetime and usability. 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.
