The “GRAVELKING ZX” features a slick tread pattern in the center to help you race through high-speed sections as fast as possible. The “Onimegasu” tread pattern on both sides—with its raised, irregular texture—truly shines in situations where traction is essential. Additionally, the shoulder knobs ensure reliable control when cornering.

The “GRAVELKING ZX +” adds an extra layer to the standard model’s construction, further enhancing its puncture resistance.
