Excellent fuel efficiency with optimized grip performance for long haul use

Center zigzag groove

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

Optimized block size

The tread block is wider than the previous product and that enhances the rigidity and reduces tire rolling resistance.

Hidden groove

At 70% wear, hidden grooves appear. These grooves improve wet grip and traction when the tire wears.

Self-regeneration Sipe

As the tire wears, sipes and grooves are revealed to give improved traction and grip performance.

Self-Regenerating Sipes & Hidden Grooves

During the entire life of the tire, Hidden Groove & Self-Regeneration Sipe technologies maintain the wet grip & traction performance.

New Tire

Hankook premium technologies deliver improved tread block stiffness, high mileage and fuel efficiency.

40% Wear

Regenerating tread features are revealed as the tire wears. These features improve wet grip and traction even when the tire is 40% worn.

70% Wear

When 70% worn, hidden grooves are revealed. These deliver improved wet grip and traction.

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.

Controlled tearing and wearing
→ Reduce irregular wear.

Improving traction and grip throughout the entire life of the tire.

Advanced Compounding Technology Compound Innovation

Improved compound performances 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 minimizing 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.
