Mastercraft Courser MSR. FEATURES AND BENEFITS: Winter weather traction; Enhanced controllability; Shortened braking distance; . OVERVIEW: The Mastercraft Courser MSR is a highway terrain winter tire manufactured for SUVs and light trucks.The model offers great winter weather traction. The detailed symmetric pattern firmly grips the road surface, even when driving on ice and snow, while the winter compound keeps its rubber flexibility in cold temperatures. The high-density D-Square siping detail enhances the ice and snow traction and gripping ability by promoting additional biting edges. The Snow Grooves pack snow into the grooves to boost the model's snow-on-snow traction and ensure a secure performing capability. The tread's wide groove pattern and open shoulder design work together to avoid hydroplaning. They disperse water and slush from below the model's footprint and improve the cold temperature wet and winter weather traction. The tire is pinned for studs, which can be added to the tread for an enhanced grip on ice- and snow-covered road surfaces.The Courser MSR is easily controlled even in the harshest winter weather. The reinforce internal structure keeps the tire's optimal shape under the driving and load pressure affecting it. The optimal shape allows the tire to closely follow the road surface at all times. The tread's continuous zigzag center rib maintains the tire's road contact to boost its steering responsiveness and driving stability. The steering becomes faster and more precise in its responsiveness to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. The high-density siping detail firmly grips the road surface and upgrades the braking capability. The sipes create friction at the moment of braking, which shortens the braking distance and ensures a secure winter weather performance. 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.
