The DUNLOP Grandtrek ST30 tire is designed for use on roads with any hard surface.
One of the few tires in its class, it has an asymmetric tread pattern with wide drainage grooves, which guarantees high self-cleaning properties from dirt.
The summer passenger tire Dunlop Grandtrek ST30 from the world-famous British manufacturer was specially created for four-wheel drive cars, the operation of which takes place mainly on paved roads. This model, produced in one standard size, is included in the original equipment of the Honda CR-V crossover, which indicates the excellent technical and operational characteristics of this tire.
This model is one of the few tires designed for off-road vehicles with an asymmetric directional tread pattern. This construction of the tread elements has given the tire a lot of advantages that are effective in any condition.
On the outer side of the tread of the Dunlop GrandTrek ST30 tire, there is a wide longitudinal rib, the rigid structure of which, when driving in a straight line, provides excellent directional stability and high efficiency of acceleration and braking. In addition, the high structural rigidity of this tread element made it possible to significantly reduce the reaction time to steering turns, which brought sporty features to the handling characteristics.
The shoulder tread areas are also characterized by high structural rigidity, which, in combination with the rigid sidewalls, significantly improved grip when cornering. In addition, the shoulder areas have a rounded profile to combat deformations leading to uneven wear.
All tread elements are equipped with sipes of various shapes and sizes, which allow for a more uniform adherence of the tread to the road surface, and also contribute to more efficient heat transfer from the tire tread.
Main features of the Dunlop GrandTrek ST30 car tire
- Unique asymmetrical directional tread design for superior traction and handling in all conditions;
- Rigid design of the longitudinal rib, located on the outer side of the tread, made it possible to achieve excellent directional stability and high braking efficiency;
- Excellent resistance to aquaplaning due to the high efficiency of the four longitudinal grooves and the system of transverse channels;
- The rigid construction of the blocks of the shoulder areas of the tread and sidewalls of the tire provides sporty handling.
The Dunlop Grandtrek ST30 is a 4x4 summer tire highly regarded by premium crossover and SUV owners. The tires of this model are distinguished by excellent performance, handling, and dynamics, behave well on dry and wet surfaces, provide safe braking and rapid acceleration.
Tread structure
The working surface of the passenger car tire Dunlop Grandtrack ST 30 consists of the following elements:
- The central stiffening rib, formed from three rows of trapezoidal macroblocks, gives the car high directional stability when driving along a straight path.
- Numerous sipes that cover the surfaces of the macroblocks create additional grip edges in the contact patch. Thanks to them, the wheels grip more confidently with the roadway. This reduces the likelihood of unwanted slipping during rapid acceleration and prevents uncontrolled skidding of the wheels during emergency braking.
- Shoulder blocks located on the inner and outer parts of the tread pattern serve to increase vehicle handling. They provide instant wheel response to steering commands and protect against dangerous drifts when overcoming sharp turns.
- The sophisticated drainage system, presented in the form of four longitudinal grooves and numerous transverse grooves, increases safety when driving through puddles and wet asphalt. Drainage channels instantly clear the contact patch from water, thereby reducing the likelihood of a hydroplaning effect.
Improved rubber composition
When designing the Dunlop Grandtrek ST30 summer tire, attention was paid not only to the tread structure but also to the chemical structure of the rubber compound. To improve all the main characteristics of the tire (reliability, handling, braking properties, etc.), the developers have added several special admixtures to the compound.
In particular, the addition of silica particles to the rubber compound has made the tires more durable and resilient. Special polymer ingredients reduce the rolling resistance index, which means that the car consumes less fuel with these tires. Moreover, all the substances that make up the rubber are safe for the environment.
Tread features
Summer tires Grand Track CT 30 gained popularity due to the special shape of the tread. He has:
- asymmetric pattern, providing the vehicle with high cross-country ability;
- increased rigidity, affecting steering sensitivity and handling;
- wide lateral shoulders, responsible for traction when maneuvering and entering a turn.
Summer tires Dunlop Grand Track CT 30 are equipped with a specialized lamella structure of various sizes and shapes. It was thanks to her that it was possible to achieve excellent grip, both on the track and off-road.
Dunlop is renowned for its development in the rubber industry. She is the pioneer of many technical solutions that even other manufacturers use. Therefore, you can be sure that its summer tires will meet the declared characteristics and their operational purpose.
Main advantages
Considering the tires Dunlop Grand Track ST 30, we can highlight their characteristic advantages:
- a special system of sipes and an asymmetric structure provide the best grip on the road in almost any conditions;
- good directional stability is combined with the ability to make sharp braking;
- excellent maneuverability characteristics typical of sports models.
The Dunlop tires of this type have become very popular with SUV owners. Drivers note their high wear resistance and long service life. These tires performed well in the conditions of domestic roads, perfectly tolerating even a strong mechanical impact when hitting pits and potholes.
Many drivers using these tires report almost no aquaplaning effect. This was achieved thanks to 4 longitudinal grooves that act as a drainage system to drain water from under the contact patch.
