Challenge Gravel Grinder 36x700

Make your mark on the gravel scene with the Gravel Grinder. This 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 tire takes tubeless to a higher performance level by combining TLR's properties with a handmade construction for the ultimate in traction and ride quality. This tire combines a supple, yet durable Corazza Armor casing for improved sidewall protection, excellent puncture-resistance from our PPS Ganzo, and a high mileage, grippy, natural SMARTplus compound. And puncture protection is enhanced when combined with the appropriate tubeless sealant. 260TPI SuperPoly casing.
