Maxxis MU521. FEATURES AND BENEFITS: Improved controllability; Upgraded driving durability; All season performance; Rugged terrain traction; . OVERVIEW: The Maxxis MU521 is a rugged terrain, all season tire made for ATVs and UTVs.The tire helps to protect the structure from damage. The tire was manufactured with a strong casing construction, which enhances the tire sidewalls and increases its puncture resistance. This ensures safer off-road driving and it makes the tire stronger. It also upgrades usability for a longer period of time. The strengthened sidewalls are resistant to accidental damage, such as tearing, chipping, punctures, and cuts. Thanks to this construction, these tires promote excellent damage resistance on rugged terrains.The model enhances versatile terrain traction. The optimal tread pattern, with the large elements, firmly grips the surface with extra biting edges. Large elements enable the tire to easily handle hard and uneven terrains. These elements keep the tire's forward motion at all times. This tread pattern also keeps the footprint clean during the performance while preventing stone retention from harming the tire's casing.The rugged terrain traction and the ideal footprint's surface contact optimize the tire's controllability. The aggressive tread design is able to increase the overall driving safety levels in this manner. The tread design boosts steering responses to the driver's commands, while the structure is secured against driving pressure. Cornering is also boosted with the shoulder blocks that provide the necessary number of biting edges.The Maxxis MU521 provides great all season traction. The optimized tread design keeps the surface contact in versatile weather conditions, while the all season compound maintains flexibility in warm and cold temperatures. They increase dry, wet, and winter-weather traction. On the other hand, wide grooves prevent hydroplaning. They eliminate water and slush from the footprint, in order to protect the tire against slipping in wet situations.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.
