You've never had traction like this on a commuter tire. The 45NRTH Gravdal wire bead tire provides superior grip in dicey conditions thanks to 252 strategically positioned steel-carbide studs.


  • 252 studs are carefully positioned across the casing profile to yield an exceptional level of confidence
  • Using 2-piece construction, each steel-carbide stud features a dome-shaped carbide tip with a steel base to provide excellent performance and longevity
  • Siped tread lugs (tiny grooves on large tread lugs) and oval-shaped stud groupings provide exceptional cornering, braking and acceleration traction
  • Run at minimum pressure for unmatched traction performance, and maximum pressure for a quieter and faster ride on clean roads
  • Features a 5 mm high-visibility strip for riding at night; fits most bikes with cantilever or disc brakes
  • Note: Tire images shown may not reflect size/color/material options available on this page
