American tire brand Cooper is known only to a narrow circle of motorists. The fact is that the company focused on the manufacture of tires for high-speed cars and SUVs. Tires of this brand are of high quality and decent value. This rubber is expensive. These statements fully apply to Cooper Discoverer STT tires.

For which machines

These tires were developed exclusively for vehicles with all-wheel drive. At the same time, they have a pronounced off-road character. The tires will provide the necessary handling on rough terrain, but on the track to accelerate to high speeds they will not work. For example, the Cooper Discoverer STT 265 70 R17 model has an N speed index. This means that the presented tires retain their performance only up to a speed of 140 km / h. When this parameter is exceeded, vibration increases, as a result of which it becomes much more difficult to keep the car on a given trajectory. The tires themselves are available in 90 different types.sizes with landing diameters from 15 to 20 inches. This allows you to choose tires for any car of the corresponding segment.

Season of applicability

The tires on the Cooper Discoverer STT are unique. The fact is that the compound of these tires is able to maintain its elasticity even with a slight cold snap. In a number of regions of Russia, these tires can be used as all-weather tires. When it gets colder below -7 degrees Celsius, the tires will quickly harden, which will significantly reduce the quality of adhesion to the asph alt road. There are no spikes. Therefore, you need to move along the icy road as carefully as possible.

A little about development

Tires of this brand are developed in several stages. First, a 3D tire model and its physical prototype are created. After that, the rubber is tested at a special stand and the company's test site. According to the test results, all the necessary adjustments were made to the model and the tires were launched into series.

Design

Cooper Discoverer STT tires received a classic tread pattern for this type of rubber.

Two central ribs consist of massive multidirectional blocks. Moreover, these elements have a polygonal shape. The presented approach allows to improve the quality of adhesion of tires to the roadway. The blocks are massive. This helps them keep their shape under strong dynamic loads.

Shoulder areas are responsible for the stability of the behavior of the tire when cornering and duringbraking. These elements consist of large blocks with complex geometry. Such a solution allows to reduce the load on the elements during this type of maneuvers. As a result, drifts to the sides and loss of control over the traffic situation are completely excluded.

Riding in the rain

Most of the difficulties for drivers arise while driving in the rain. The Cooper Discoverer STT tires are designed to resist hydroplaning for incredibly safe driving in bad weather.

Engineers have equipped these tires with an advanced drainage system. The shoulder zones have a fully open design, which further increases the speed of water removal from the contact patch. The increased dimensions of the transverse and longitudinal tubules increase the volume of fluid removed per unit of time.

To improve the quality of grip with the roadway, silicon compounds were added to the rubber compound. Tires Cooper Discoverer STT literally stick to the pavement. Demolitions to the sides are excluded.

Mud and snow

The presented tires effectively remove dirt and snow from the contact patch. Massive blocks quickly push through these types of surfaces, resulting in better traction. Adhering clods of soil fall under their own weight. The tread does not clog in principle.

Durability

Drivers also note the increased durability of the presented model. Performance characteristics remain stable even after 70 thousand kilometers. Such impressive resultswas achieved thanks to an integrated approach.

The tire design itself had a positive effect on wear resistance. The fact is that this type of tire is distinguished by a more complete distribution of external pressure over the contact patch. Tires wear evenly. Naturally, this is only possible if the pressure level in the tires is controlled.

In the manufacture of the compound, the concern's chemists increased the proportion of carbon black. This helped increase the wear resistance of the tread. Abrasive wear is much slower.

The presented model has a reinforced frame. The metal cord is bonded to nylon. With the help of an elastic polymer compound, it is possible to extinguish excess impact energy. Sidewalls received additional strengthening. As a result, the likelihood of bumps and hernias is reduced to zero. Cooper Discoverer STT tires are not afraid of even side impacts.

Comfort

Reviews indicate that these tires are quiet. The Cooper Discoverer STT managed to reduce the amount of noise due to the variable distribution of tread blocks. The sound wave generated by friction on the asph alt road is damped by the tire itself. The rumble in the cabin is excluded.

With all this, the rubber is also distinguished by its softness. Shaking in the cabin is completely excluded.

Opinions

In reviews of the Cooper Discoverer STT, drivers note, first of all, the incredibly high cross-country ability of this rubber. Even difficult off-road conditions are no problem whatsoever. Tires will take the car out of any dirt. The only downside isprice. These tires belong to the premium segment. The cost starts from 9 thousand rubles per wheel. Moreover, the larger the radius of the rubber, the higher the final price. For example, the Cooper Discoverer STT R20 costs up to 26 thousand rubles.
