The Kumho Grugen Premium summer tire is designed for use in mid-size crossovers, representing a High Terrain category model. It is characterized by reliability in handling on wet surfaces, effectiveness in braking in any weather conditions, fuel efficiency, and resistance to wear.
The tread pattern is notable for the presence of a large number of lamellas. In the central part, X-shaped slits are used, which have extended functionality. These elements allow the blocks to adhere to the road surface over a larger area, which improves traction and reduces the level of abrasive impact on the tread, reducing noise and vibration. The shoulder blocks contain straight lamellas, forming elongated transverse edges, which provide more intensive braking on wet surfaces. It is also worth noting the presence of additional semi-spherical cavities in these slits. With their help, additional drying of the contact patch is carried out, which reduces the risk of aquaplaning, providing more reliability in handling on wet surfaces. Another important feature of the tire is the tread profile with variable curvature. In combination with a fairly dense arrangement of tread pattern elements, this expands the contact patch, aligning its edges, maintaining shape and size under the influence of various acceleration forces on the tire. As a result, the coupling properties not only increase but also become stable, regardless of driving conditions, which significantly simplifies control over the vehicle's trajectory.
Key features of Kumho Grugen Premium:
- X-shaped lamellas in the central part improve traction and handling, prevent wear, reduce noise and vibration;
- straight slits in the shoulder blocks with additional cavities increase the intensity of braking on wet surfaces;
- massive shoulder areas with optimized profile provide reliability of handling during maneuvers, reduce uneven wear of the tread.
