Low profile tread design uses diamond knurling to reduce rolling resistance and enhance grip in dusty loose conditions. 
Paddle knobs arranged in sets of three provide extra bite under hard braking. The side knobs are spaced closely together and are staggered for consistent cornering performance. A sipe (groove) in each of the side knobs allows them to flex and conform to the terrain, improving traction. The Reaver is ideal for racers as it is faster, lighter, and even more durable than the vulnerable Rambler. In mixed conditions or deeper gravel, the Rambler is more versatile but if off-road speed is a priority number one, choose the Reaver
