The American company Coopertires this year celebrated the 100th anniversary of the start of tire production. During this time, the manufacturer has become one of the leading tire suppliers in the US market. In the world market, it also occupies a worthy place and has 7 industries located in different countries.
This is facilitated by the use in the development and manufacture of tires of modern and original technologies that distinguish the company from competitors. Coopertires focuses primarily on the secondary market, motorists buy these tires consciously, due to their high quality. The company's products are practically not supplied to the conveyors of automobile plants.
General characteristics
Cooper Discoverer M + S tires have a deep symmetrical tread pattern . Powerful channels expanding to the surface are located between the tread blocks. This design allows the tire to self-clean very effectively from snow and dirt, which ensures a clean tread in the contact patch.
The shoulder area is made in the form of angular blocks with additional indentations in the middle. This allows the tire to operate confidently in mud and loose snow. The central part of the tread blocks is made in the form of a zigzag stiffener. On both sides it is surrounded by tread blocks, forming additional stiffening ribs. This design allows you to achieve high directional stability and controllability of the car.
The tread has deep lamellas, which effectively absorb moisture and reliably hold the tire on slippery surfaces. And deep transverse channels quickly remove excess moisture from the grip spot. Holes for mounting studs are provided in the tire. Their main part is located on the side blocks of the tread and in the shoulder area, which reduces the noise level from the spikes.
Tire design
The design of Cooper Discoverer M + S is designed using computer technology. Due to this, the tire has excellent balance and low weight, which provide minimal load on the car's suspension. In addition, the load is evenly distributed throughout the tire carcass, which allows to reduce its wear and increase the term of use.
The composition of the rubber mixture used to make the tire consists of 3 components. A stiffer composition is superimposed on the cord frame and provides
protection against cuts and punctures. For the manufacture of the tread, two compounds are used, the softer is intended for blocks with lamellas and works on ice. Hard is used for the checkers of the shoulder area, which are responsible for the patency of the tire through mud and snow porridge.
Soft rubber compound is used in the sidewalls, which allows to reduce the noise level during movement. To protect the side zone from cuts and punctures, it is reinforced with an additional layer of cord fabric. The use of modern organosilicon components in the rubber allows the tire to remain soft and elastic even in the most severe frosts.
Driving performance
As evidenced by numerous reviews, Cooper Discoverer M + S perfectly cope with both snowy and icy roads, and off-road. This allows you to use them in the offseason, when the weather is not stable and changes rapidly. Separately, the wear resistance of these tires should be noted. The manufacturer gives a guarantee of 55,000 miles, which is approximately equal to 90,000 km.
Excellent traction and hitching characteristics are ensured by the soft composition of the blocks on which the lamellas are located, a self-cleaning system and a deep tread structure. The serrated shape of the tread elements provides additional traction with the ground, snow floor or ice.
The use of silica in the rubber composition provides the tire with high elasticity and reduces rolling friction. The result is increased tire strength and increased acoustic comfort for the driver. Reducing friction gives another serious result - fuel economy. Despite the fact that gas prices are constantly growing, this is becoming an increasingly significant advantage.
The use of spikes
For installation in a tire two-flange spikes of a round form are used. Since the tire can be produced without spikes pre-installed at the factory, various modifications can be applied. But the landing sockets are designed specifically for installing round studs with two flanges.
Landing nests are made of a more durable rubber compound, which ensures reliable mounting and durability of the studs. Since it is not possible to verify where the spikes were installed, they must be checked. To do this, it is enough to throw the tire several times on the floor from a height of human growth.
Road behavior
If the spikes do not match the tire or are incorrectly installed, some of them will fall to the floor. For a more meticulous check, you can press on the inside of the tread blocks where the spikes are installed, if they hang out, or even fall out - it is very likely that the tire will remain without spikes very soon.
But even without the spikes installed, the Cooper Discoverer M + S copes with off-road conditions, packed with snowy ice and ice. Computer-designed lamellas of various shapes allow it to work like a Velcro bus. And the sharp edges of the tread blocks and the protruding shoulder area provide adhesion to the ground and deep snow.
Cornering stability
Three large central longitudinal stiffeners allow confident cornering. In addition, they provide accuracy and information control when performing maneuvers. Additional support in the form of protruding tread blocks in the shoulder area allows you to achieve high lateral stability when driving.
The optimal arrangement of the spikes allows you to drive confidently in the most difficult weather conditions. This arrangement also allows you to achieve a low noise level when driving. During acceleration, the tread design and the location of the studs prevent slipping, which also increases the service life of the tires.
The stiff design of the carcass allows the tire to maintain its original shape even at high torsional loads arising from cornering. A soft rubber composition with numerous lamellas literally sticks to a slippery road. All these design features allow you to confidently take turns at high speed, both on the road and on slippery road surfaces.
Assortment and purpose
Model Discoverer M + S
spike (Cooper) is available in 30 sizes. Starting from tires for mounting on wheels with a diameter of 15 inches and ending with 20 inch models. This product range allows you to cover a very large number of cars. Tires for 15-17 inch wheels can be installed on cars, as well as on crossovers and SUVs.
These tires are particularly well suited for installation on off-road vehicles, crossovers and pickups. This is evidenced by the presence in the assortment of tires for 19 - 20 inch wheels. The design itself and the tread design allow the use of these tires on impassable terrain.
In addition to tires for cars and SUVs, the model range also includes tires designed for light trucks. They are marked accordingly - Cooper Discoverer M + S LT. The LT index means that they can be used on light trucks.
Having received excellent reviews from car owners from around the world during the operation, Cooper Discoverer M + S was continued in the new model of the manufacturer. She received the name Cooper Discoverer M + S 2 and includes all the best features of its predecessor and the latest developments of the manufacturer.

Tires Cooper Discoverer M + S
Sport
One of the new friction tire designs from Coopertires. It is intended for car owners who practice an active driving style. The tire is available without studs and has an original asymmetric tread pattern. This allowed the Cooper Discoverer M + S Sport to achieve the lowest noise level in this class of tires.
Specifications
A special snow groove closer to the outer sidewall of the tire? Helps to effectively push water and snow sludge out of the contact patch. The composition of the rubber mixture is different for different parts of the tire, which allowed to achieve high tire strength and excellent traction and coupling characteristics. The soft composition of the tread blocks, where the lamellas are located, provides a reliable grip with slippery and wet surfaces.
The Cooper Discoverer M + S tire, reviews of which exceeded the manufacturer's expectations, inspired him to develop this model and to launch a novelty for dynamic driving enthusiasts on the market. The use of silicon dioxide in the composition of the rubber compound allows to increase the elasticity of the tire. On the one hand, this increases the grip of the tire on snow and ice, and on the other hand, it reduces rolling friction, which saves fuel.
