The DUNLOP Grandtrek AT23 tire is designed for off-road vehicles. Suitable for both asphalt roads and off-road. Due to the special structure of the working surface, the tire demonstrates high-performance indicators on various types of roads - asphalt, unpaved, etc. Due to the presence of sipes and the acute-angled shape of rubber blocks, an excellent grip is achieved even on wet and snowy surfaces.
The main distinguishing feature of the Dunlop GrandTrek AT23 off-road tire is its versatility. This fully corresponds to the scenario of using those vehicles for which this model is intended. It is characterized by reliable grip not only on summer but also on winter surfaces. This is ensured not only due to the presence of the abbreviation M + S on its sidewalls but also due to the original design of the tread pattern. However, this is only one of the many advantages of this tire, which will be discussed below.
Symmetrical tread pattern
The tread blocks are located on the working surface of the tire in 5 rows (3 central and 2 shoulders). Deep drainage channels are provided between them, which prevent aquaplaning and ensure high safety when driving on wet asphalt. A narrow stiffening rib passes through the central part of the tread, which increases the directional stability of the car. On both sides of it, there are additional rows of S-shaped blocks, the main task of which is to improve traction, shorten braking distances and prevent wheel slip during sharp acceleration.
Shoulder design
The shoulder ribs are formed from rigid rubber blocks of variable width. Lamellar blocks are located at a certain slope relative to the longitudinal axis and have wavy contours. It is these structural elements of the tread that are responsible for the car's handling when performing sharp maneuvers. When the steering wheel is turned, the shoulder blocks "cut" with sharp edges and edges of the sipes into the road surface, as a result of which the risk of lateral wheel slippage is reduced and side skids are prevented.
Travel comfort
The center and shoulder ribs have been designed to provide optimum traction without compromising on acoustic performance. When driving on hard asphalt roads, tires do not create perceptible noises that cause discomfort to people in the car. Due to the elastic structure of the compound, the tires can smooth out small irregularities in the roadway and absorb the resulting vibrations.
Fuel savings
The rubber compound containing polymer additives has a low rolling resistance. This means that when driving on asphalt and concrete roads, there is no excessive fuel consumption due to excessive frictional forces in the contact patch. Thus, with Dunlop GrandTrack AT23 tires, travel becomes not only more comfortable and safe but also less expensive.
High level of comfort
One of the main advantages of this tire is a high level of comfort, above all, acoustic. It is provided due to the features in the design of the tread pattern, namely, the 5-step arrangement of all its blocks. This greatly reduces the likelihood of resonance noise and vibration. At the same time, the use of three-dimensional modeling technologies in the development of this model made it possible to choose such a combination of the location, shape, and size of the tread blocks, in which they generate a minimum of noise.
Confident behavior in adverse weather conditions
Most of the attention of the British brand specialists involved in the development of the Dunlop GrandTrek AT23 tire has been given to maximum safety in adverse weather conditions. This was achieved through the tread design. First of all, this is an increased number of coupling edges, formed both by blocks and by lamellas cut into them. In addition, improved grip on slippery surfaces is provided by the rubber compound with higher silica content.
Main features of the Dunlop GrandTrek AT23
- reliable behavior in difficult situations thanks to an optimized tread pattern with an increased amount of grip edges;
- low noise level due to the use in the development of technologies of three-dimensional modeling and a tread with a 5-step block arrangement.
Pros: excellent summer tires for asphalt. Excellent road holding, the car does not "float" in the heat.
Disadvantages: maybe the price.
Commentary: Great rubber.
