What Our Gearhead® Experts Are Saying: "I threw these on my dirt jumper and instantly noticed the difference—these tires are mad light and super grippy. They roll insanely smooth on hardpack, and they’re forgiving when landing a little sideways. The micro-teeth hook up surprisingly well even in dusty corners. They're perfect for pumptrack days or jump line laps."Schwalbe’s fast, fun, and forgiving Billy Bonkers Tire is made for days at the pumptrack, dirt jumps, and slopestyle lines. At just 490g, it’s light enough to whip around and boost easily, with a tread pattern that’s dialed for speed and traction on hardpack and loose-over-hard surfaces. The micro-textured tread offers confidence when throwing tricks or railing berms, while closely spaced knobs add a consistent feel whether we're pushing hard into a landing or pedaling into the next set. The Addix Performance compound keeps the tire soft enough to grip but firm enough to roll quickly, and small ramps built into the tread help convert pedal strokes into instant acceleration. When we’re sessioning lines or stacking laps on dusty rollers, Billy Bonkers is the tire that keeps it playful and under control.
