Center Zigzag Groove
The center zigzag grooves create a binding effect on each tread block contributing to better rolling resistance and traction.

Optimized Block Size
Wide tread blocks enhance the tire's rigidity and improve the mileage while delivering low rolling resistance.

Self-Regeneration Sipe
As the tire wears, sipes and grooves are revealed to give improved traction and wet performance.

Horn Shape Self-Regeneration
Stress on the shoulders is reduced by applying horn shaped self-regenerating sipes that prevent cracks. They also provide enhanced water evacuation which delivers improved wet performance.

Integrated Premium Technologies: Self-Regeneration Sipe
Hankook premium technologies deliver high grip and mileage performance from the first to last milimeter of tire life. Our 'no compromise' development approach ensures that low rolling resistance is maintained at all stages of wear, thereby benefitting both your budget and the environment.

40% Wear
Interlocking deep depths 3D sipes are revealed, thereby supporting tread block stiffness to maintain the high level of grip and low rolling resistance.

70% Wear
At 70% worn, Self regenerating lateral grooves appear. They deliver additional traction and wet grip performance.
3-dimensional sipe
Full Depth 3D sipes maintain excellent mileage and traction throughout the entire life of the tire by reinforcing and interlocking the tread blocks.

Advanced Compounding Technology Compound Innovation
Improved compound performance by introducing the carbon-silica dual filler system. This system improves the homogeneity of the rubber compound mixing. The benefit is that the fuel efficiency is increased by using this new polymer and silica filler. Fuel efficiency is increased by using a new polymer and silica filler.

Innovative Mixing System
The Innovative Mixing System (IMS) minimizes the disconnection of the polymer chain and oxidation. The carbon black reinforcement also has higher dispersion levels. These effects of IMS help strengthen the bonding force between the carbon black and rubber for a stronger compound and lower heat generation.
The benefits of IMS are higher mileage and fuel efficiency.

1 Step
Larger molecular weight by minimising the breakdown of the polymer chain.

2 Step
Increased strength and decreased heat generation.

Mixing
Higher mileage and improved fuel efficiency.
Stiffness Control Contour Technology (SCCT)
SCCT is designed for constant profile deformation. If the casing profile cannot be kept constant, the internal force on the casing will be concentrated on a specific point (belt edge or turned up casing edge). In contrast, SCCT controls the dispersion of internal forces for better durability.

SCCT allows Hankook Tire to develop tires by balancing optimum stiffness with the contact shape. The benefits of this technology are improved performance, safety, cornering, braking and durability.
