Cooper Discoverer M+S Review

Winter tires offer excellent cold temperature performance. These models improve the grip on the road surface and maintain their controllability to ensure a safer driving experience in various cold weather conditions.

The Cooper Discoverer M+S is one of our most popular models at Priority Tire. This model was manufactured for SUVs and light trucks and it comes in a versatile size range. The tire guarantees exceptional winter traction, handling and even an extended tread life to ensure a safer performing capability.

Winter Weather Traction

Tires stamped with the three mountain peak and snowflake symbol ensure first-rate severe winter weather performance. These tires use their tread pattern and winter compound to boost the cold temperature dry, wet and slippery surface performance.

The Discoverer M+S used its tread design to enhance the grip on the road surface in winter weather, while it utilizes the special winter compound to ensure a safer performance. The compound keeps the rubber flexibility in colder temperatures, ensuring a safer driving experience. The tread design, with the detailed siping pattern and the unique Snow Groove design boost the grip on the road surface.

These tread elements significantly increase the number of biting edges gripping the ice- and snow-covered road surface conditions. The snow groove pattern enhances the traction with snow-on-snow grip by packing snow between the tread elements. The sawtooth center rib ensures forward motion and grip on harsher winter weather surface conditions. The tread design’s D-square siping pattern provides additional biting edges that firmly grip the road surface during the drive. Furthermore, the tire is pinned for studs, which can be added to aid the ice and snow grip.

The tread design’s straight and zigzag circumferential grooves help prevent hydroplaning. Hydroplaning happens when slush and water located on the road surface cut off the tire’s surface contact, causing the vehicle to skid and the driver to lose control over it. The tread pattern, in this manner, manages to channel water and slush away from the footprint, maintaining the tire’s surface contact at all times. This greatly improves the wet and slippery surface performing ability of the tire.

Controllability and Handling

Winter tires must have good controllability in order to ensure safer driving experience in such conditions. A tire’s tread design and internal structure work together to enhance their steering responsiveness, driving stability and overall handling in versatile cold temperature conditions.

The Discoverer M+S maintains a close surface contact throughout the model’s performance with the continuous center rib. The better road contact enables the tire to improve the steering responsiveness and the driving stability. In other words, the model is faster and more accurate in its response to the driver’s commands, while the structure is stabilized against the driving pressure affecting the model. This allows the driver’s full control over the vehicle throughout its performance, guaranteeing a safer driving experience.

The detailed shoulder pattern and siping design work together to enhance the maneuvering and braking ability. The shoulder tread block placement with the high-density siping pattern enhances the cornering and maneuvering ability by increasing the number of biting edges gripping the road surface throughout the drive. The detailed siping pattern also boosts the braking power by creating friction between the tire and the road surface at the moment of braking, significantly shortening the braking distance. In this manner, the tire ensures a safer controllability in severe winter weather.

Longer-Lasting Tread Life

Even with winter tires, a longer tread life is a desirable feature. The more tread a tire has, the better its friction and this is truer for winter tires. Such tires need adequate tread to safely perform in winter weather. As a result, manufacturers strive to increase their usability with various tread designs.

The Discoverer M+S features a symmetric tread design with optimally placed tread blocks and a continuous center rib. These tread elements help maintain a constant surface contact and stabilize the tread area during the drive, which ensures the tire’s even pressure distribution. The improved surface contact allows the tire to equally spread out the forces of acceleration, cornering and braking across the tread area, while the prevention of tread flexing avoids unnecessary friction formation along the tire’s surface. This combination ensures the tire’s lengthened tread life and usability.
