The Vulcanite is a go-anywhere tire featuring tall knobs for traction in loose terrain, hatch marks and siping for additional traction in packed conditions, and ramped central knobs for straight-line speed. And its semi-open tread block layout reduces debris build-up while increasing bite on rocky terrain and roots. 

The Vulcanite is available in both Trail and Enduro versions with casing, construction, and tread compounds specific to the intended use. Trail models feature our Stage TR Armor construction for efficient climbing, predictable cornering, and long days on singletrack. Enduro models feature our Stage EN Armor construction for a tire that provides grip through blind corners, confidence over rock gardens, and the ability to cruise back up the trail. Both Stage TR Armor and Stage EN Armor constructions are Tubeless Ready.
