QIRIN 990

PRECISE HANDLING AND STRONG BRAKING

A high-performance sport tyre. An asymmetric tread design whose outer blocks speed up steering response and improve steering performance. 3D sipes with chamfered edges enlarge the contact area under braking and acceleration for traction, and enlarge the heat-dissipation area for durability. Four wide main grooves drain water for wet-skid resistance, and a strong centre rib improves handling stability and straight-line running at high speed. Five-pitch tread blocks in a computer-optimised sequence lower pattern noise, and the land-to-sea ratio with an optimised tread compound lowers rolling resistance and fuel consumption.
