Description
If you’re running trials or mixed-surface racing, tire choice makes the difference between precise control and unpredictable grip loss. The IRC GP-1 delivers aggressive traction on loose terrain without the accelerated wear that full-knobby designs suffer on pavement, giving you a tire engineered for genuine on-and-off-road performance. Whether you’re tackling rocky descents or technical street sections, the GP-1’s strategically designed knobs bite hard where it matters while maintaining composure during braking and cornering across variable surfaces.
