The radder version of WTB's famed Riddler tread pattern, the Raddler combines the supple traction of a high-volume gravel tire with the rolling efficiency of a short-knob tread design. The minimalistic centerline allows you to maximize the output of every pedal stroke, while toothy outer knobs provide cornering confidence that refuses to let up. The time-tested Raddler is an excellent choice for unpredictable roads or trails where traction is key, but efficiency is of utmost importance.

Shorter center knobs cut down on rolling resistance while still providing ample bite for out-of-the-saddle pedaling. Increased outer knob height allows them to bite in the earlier phases of cornering and therefore provide the traction you need on loose gravel roads.
Siped Outer Knobs
It's not often you see knob siping on a gravel tire, but Raddler isn't designed to be like every other tire. Sipes run the full length of each side knob to double their working edges and drastically improve cornering traction in both loose and wet conditions.
Extended Tread Life
Slightly taller overall knob height throughout the tread compared to the original Riddler tire, which increases longevity without a noticeable change in rolling efficiency. Taller knobs pair well with it radder, hard-charging usage.
TCS (Tubeless Compatible System) is WTB's standardized tubeless system. These tires feature a TCS tubeless-ready casing, which nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tube-type tire.
Available with SG2 puncture protection
SG2 is our unique puncture protection technology that provides bead-to-bead coverage to ensure both the tread and sidewall are protected from slashes and punctures. The nylon fibers within SG2 feature a uniquely flat profile, which reduces the amount of rubber between fibers. Improving the fiber-to-rubber ratio increases puncture resistance, reduces weight and improves the overall liveliness of a tire. While SG2 is primarily a puncture protection layer, its tightly woven fibers also improve air retention to better maintain pressure between rides.
Black or tan sidewalls
It's nice to have options, which is why most of our gravel tires are available with either black or tan sidewalls. Traditional black sidewalls tend to blend in with the components and wheels of a bike and may look sleeker in the eyes of some riders. WTB tanwall tires blend retroesque looks with modern technology to create an iconic look that has become synonymous with high-performance gravel. Looks aside, gram counters may choose our tan tires because the compounds used to make them are slightly lighter than those used to manufacture black sidewalls.
