Rock Conqueror

Heavy-duty muscle fat bike tire for muddy and gravelly terrain
The Rock Conqueror's "Big Convex Button" was first designed and used on fat tires for Jeeps. The large, iconic protruding blocks on its surface represent the conquest of the rocky terrain. Rock Conqueror faces challenging terrain directly such as rocks, forests, and mud inaccessible to ordinary tires. Featuring heavy-duty rubber and puncture-resistant technology, these tires are designed for e-bikes for greater load-carrying capacity (266 lbs) and durability.
High-strength rubber with enhanced thickness and tread quality allows for greater load-bearing capacity and puncture resistance. Oversized Convex Knobs studded tread provides excellent stability and great bite to absorb rocks, and other challenging terrain.
