  • Features

    • 252 extra-large studs use a 2-piece aluminum body with a wide concave carbide tip so you get maximum bite without the weight, and they are easily replaceable and hard wearing
    • Studs feature carbide tips with a concave shape on the crown which creates a very sharp attack angle to the surface, resulting in an unparalleled amount of traction.
    • Deep center lugs aggressively claw into unconsolidated snow for extreme acceleration and braking traction
    • Super tall side lugs slice into surfaces to provide cornering accuracy and confidence
    • Tubeless ready
    • 120 threads per inch (TPI)
