This technology enables the equal distribution of the force of accelerating, braking and cornering on the tire's tread and road contact area, evenly dividing the stress and pressure across the tire. This equal pressure prevents irregular wear and makes the tire's tread life last longer. The even distribution of the stress and load on the tire, due to the Stress Equilibrium Casing (S.E.C.) boosts the tire's all weather traction as well.
