Gravel tread designed to take you beyond where the pavement ends, to where the terrain is less maintained. Its design includes a tightly packed, fast-rolling center for straight line control and speed, open transition knobs for either sandy or wet terrains, and more aggressive shoulder knobs for controlled cornering and stability in loose conditions. With our RACE construction, we start where other tires stop - we utilize ultralight 60TPI Nylon Superlight casings and superior tread compounds - to give our traditional vulcanized tires excellent ride feel and quality that is more affordable than our handmade offerings. This Challenge TLR model is hookless rim compatible. SERIES: RACE (Vulcanized)Value and Performance – It's tough to beat the durability, good performance and low cost of vulcanized construction.

COMPOUND: SMART-VA specially formulated version of our SMART compound that is adapted to the different construction of vulcanized tires. PUNCTURE PROTECTION: PPSOur Puncture Protection System (PPS) is a tough, tightly-woven fabric placed between the tread and casing to increase puncture resistance.
