1) Power inside shoulder
The high-rigidity shoulder delivers superior steering stability. The highly rigid tread block ensures resistance to uneven wear.
2) Inside narrow groove
Ensures wet grip performance in the circumferential direction of the tyre.
3) Optimised lug groove layout
Air pumping noise was reduced by optimising the position of the non-penetrating lug grooves and dispersing the timing of contact between the grooves and road surface.
4) Triple Centre Rib
Three high-rigidity ribs ensure straight-line stability at high speeds.
5) Silent edge groove
Grooves cut unti the inner sides of the ribs reduce the pass-by-noise.
6) High-rigidity active shoulder
Ensuring shoulder stiffness by placing non-penetrating grooves and sipes ensure handling performance and anti-wobble when changing the lane.
7) Four straight grooves
Four main grooves ensure wet grip performance while delivering high resistance to aquaplaning and performance in wet conditions.

Acoustic pressure simulations lead to the optimal layout for five types of pitches. Pattern noise that is conspicuous on paved roads is suppressed.

Smooth road contact surface shape and uniform contact pressure achieve uneven wear resistance and outstanding straight-line stability.
1) Smooth road contact surface shape contributes to uneven wear resistance.
2) Optimised road contact surface shape length of center area provides straight-line stability.

Nano-blend rubber includes silica and polymer
1) Silica that affects fuel economy
2) Silica that affects wet grip performance
3) Polymer that affects wet grip performance
4) Polymer that affects fuel economy

Improved dispersion and uniformity of silica within the compound.
*A.R.T. = Advanced Reaction Technology in Mixing

A.R.T. mixing implies blends with refined reaction control.
Better dispersion than conventional blending technology. Braking distance in wet conditions is reduced with the same compound.
