-
Tread Design: Non-directional, aggressive block tread pattern with deep self-cleaning grooves designed to grip effectively in mud, sand, gravel, snow, and rough rocks.
-
Dual-Layer Compound: Formulated with a specialized high-silica compound that resists cuts, chips, and heat buildup during continuous long-distance highway travel or aggressive off-road use.
-
CTIS Compatible: Designed to work with Central Tire Inflation Systems (CTIS), allowing operators to safely air down for increased traction in soft terrain (such as sand or mud) without unseating the bead.
