Widely spaced knobs to help shed mud and make riding easy even on heavy terrain. The central tread has reinforced small knobs for great traction and improved rigidity without extra weight. The ramped knobs keeps tyre noise and rolling resistance low. PRB puncture resistant belting under the tread improves reliability. Argo casings are marked with arrows showing the two directions in which the tyre can be fitted, for either speed or traction.
