Combining traction and rolling efficiency, the time-tested WTB Raddler TCS tire is an excellent choice for unpredictable roads or trails where traction is key, but efficiency is of utmost importance.


  • The minimalistic centerline allows you to maximize the output of every pedal stroke, while toothy outer knobs provide cornering confidence
  • Semi-slick tread with shorter center knobs cuts down on rolling resistance while still providing ample bite for out-of-the-saddle pedaling
  • Increased outer knob height allows them to bite into the earlier phases of cornering and provide the traction you need on loose gravel roads
  • Slightly taller overall knob height increases tread life without a noticeable change in rolling efficiency
  • 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
  • Built with TCS (Tubeless Compatible System), the standardized WTB tubeless system
  • TCS tubeless casing nearly eliminates flats and allows lower tire pressures to improve traction and comfort compared to a traditional tube-type tire
  • Ideal for dirt, gravel, and loose or wet conditions
  • Note: Tire images shown may not reflect size/color/material options available on this page
