Your Gravel Grinding Companion

Challenge Gravel Grinder Pro TLR Tire combines a fast-rolling diamond center with aggressive shoulder knobs that only hook up when the terrain gets soft, muddy, or a bit sketchy.

This handmade clincher combines a supple, 260TPI SuperPoly casing with natural rubber tread for long-distance comfort, confident cornering, and quick handing.

It also includes PPS2, a combination of Challenge's sub-tread Puncture Protection System, and an additional layer inside the casing to increase resistance to punctures.

Features

  • Casing: SuperPoly Corazza Armor
  • Bead Type: Aramid
  • Protection: PPS2
  • Tubeless-Ready
  • 260 Threads Per Inch

Super Happy with these tires

Very nice tire. They provide a great ride--supple and compliant. They are the nicest gravel tire I've owned. However, they are a pain in the ass to install. You almost certain will need another set of hands and tire levers to get these things on the rim.
