Challenge Gravel Grinder Pro TLR

The Challenge Gravel Grinder has made its mark on the gravel scene. The 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. The tire takes tubeless to a higher performance level by combining TLR's properties with handmade construction for the ultimate traction and ride quality. The PPS2 combines our under-the-tread Puncture Protection with an additional Bead to bead layer in the 260 TPI SuperPoly casing.
