The Dunlop GrandTrek ST20 tire is the result of a collaboration between Japanese and German tire manufacturers. It is a unique all-season SUV tire. The tire will allow you to always feel comfortable on any road and in any weather. When developing this tire, the company's specialists tried to realize better quality summer and winter tires. They managed to achieve this by using the latest equipment and the latest achievements in the tire industry in production. The main emphasis was on cross-country ability and safety.
The tires are designed for installation on four-wheel-drive vehicles that operate in difficult conditions. The Dunlop Grandtrek ST20 positions itself as an all-season one. Multi-layer rubber allows for extended service life. The rubber used for the manufacture is abrasion-resistant and also provides a smooth ride and reduces the noise level in the cabin. Longitudinal channels allow you to clean the contact area with lightning speed and eliminate the possibility of slipping on a wet road.
Advantages of using the Dunlop GrandTrack CT20 tire:
- The mirror-symmetrical non-directional tread pattern was created using computer simulation technology to achieve maximum traction and grip characteristics of the car on wet and snowy roads.
- The two central stiffeners are made of a chain of beveled S-shaped blocks, characterized by a large number of sharp edges that act as lugs. Sharp edges of the blocks effectively increase the quality of the car's grip on the winter road. This technology eliminated the need for tread sipes.
- Antidirectional swept stiffeners provide high directional stability of the vehicle on a wet, snowy, or icy road, reduce its braking distance and prevent axial displacements during high-speed maneuvering or braking.
- The drainage system of the Dunlop GrandTrek ST20 tire is formed by a frequent network of deep longitudinal and transverse channels, through which a large volume of water, mud, snow "porridge" and sludge is removed from the contact zone, preventing aquaplaning on a wet road, and slipping of a car on a winter road.
- The shoulder tread area is made of a dense chain of U-shaped macroblocks, which increased the car's responsiveness to steering wheel movements, increased its maneuverability and high-speed cornering accuracy.
- The use of silicone-polymer additives in the rubber compound increased the level of wear resistance of the Dunlop Grand Track CT20 tire and the degree of its resistance to mechanical damage.
Disadvantages:
- Dunlop GRANDTREK ST20 tires are a bit noisy. However, for most drivers, this property is not negative. All the positive aspects cover this small drawback.
Increased cross-country ability is provided due to the optimally selected tread blocks as a result of the use of the computer simulation method when creating the tread. The combination of optimally matched blocks and increased tread depth increases the tire's self-cleaning capability, resulting in increased cross-country ability and handling. The reinforced shoulder area not only prevents damage but also provides confident handling when cornering. The reliability and safety were increased due to a specially designed frame, which was made of high strength nylon cord.
In summer and winter, the Dunlop Grandtrek ST20 tire provides precise steering response and comfort, which is important for SUVs. Also, the tire has excellent resistance, excellent braking, and load characteristics on any road surface. When driving off-road, this tire has proven itself perfectly, and boldly copes with any difficulties. The specialists managed to achieve the low speed of the tire due to changes in the geometry of the blocks. The variable element widths provide excellent acoustic comfort. At the same time, this block structure is excellent for movement in various weather conditions. Regardless of humidity and season, the Dunlop Grandtrek ST20 universal tire provides complete safety for both the driver and passengers, excellent braking, and excellent feedback.
Main features of the Dunlop GrandTrek ST20 tire
- the protector has a "two-in-one" pattern with five ribs for uniform distribution of the load in the contact patch, which made it possible to reduce the noise level and increase the service life;
- high tread with the addition of silica provides excellent traction and coupling characteristics and high wear resistance;
- Long side grooves provide excellent resistance to aquaplaning and increase the tire's self-cleaning ability.
