2.1_Tread Design
4-Channel-Drainage
The optimal width and positioning
of the four channel grooves ensure
safety on wet roads.
Wide Center Rib
for superior handling
and shorter braking distances.
Lateral Shoulder Grooves
Designed to improve handling
on dry roads and reduce then
any decline in performance
under rainy conditions and ride.
Shoulder Rib Block
Minimizing vibrations for greater ride
comfort and more precise handling.

2.1_Tread Design
Ideal Use of Grooves
The number and width of the straight grooves are optimized according to the tread width to deliver a superior
handling and hydroplaning performance.
4 channels for tires
185 mm and wider
3 channels for tires up to
175 mm wide

2.1_Tread Design
Hydroplaning Resistance
The tire contact area on the wet surface is clearly expressed in black, while the blurred parts show where the tire is
separated from the road surface by water. The greater the black area, the better water is channeled away. This helps
the tire to resist hydroplaning and improve handling and braking performance in wet weather.

2.2_Compound
HGS (High Grip Silica) Compound Technology
HGS increases molecular movement in the tread, which leads to a more flexible adaptation of the tread compound
to the road surface. This brings more rubber on the road, resulting in better grip and therefore more safety.
High Performance
2.2_Compound
Special Resin
The use of a special resin increases the tire’s interaction with the road surface.
Migrating resins in the tire’s surface ensure maximum stickiness and outstanding grip.

2.3_Construction
SCCT Mold Profile
The application of our advanced SCCT (Stiffness Control Contour Theory) mold profile delivers uniform
contact pressure on the center and shoulder blocks for shorter braking distances.
