Knobby tires feature a tread pattern composed of prominent rubber blocks designed to grip loose or uneven surfaces. These protrusions, often called knobs, dig into dirt, mud, and gravel to provide traction where smooth tires would slip.
The spacing and shape of the knobs dictate how the tire performs in different off-road conditions. Wide gaps between the blocks help shed sticky mud, while closely packed knobs roll faster on hard-packed trails. For example, a mountain biker will choose aggressive knobby tires to stay upright on a slippery, leaf-covered forest descent.
On paved roads, these tires feel much slower and make a distinct humming sound due to high rolling resistance.
High knobs provide excellent braking control but can feel squirmy on solid rock or pavement. You must balance your need for grip with your desire for speed on your local terrain. They are the defining feature that allows a bicycle to leave the road behind.
