At DMG Motorsports, we present the Shinko 540 Series Front 80/100-21 51M Bias TT (SKU 87-4302) — a purpose-built off-road tire engineered for riders who push into the deepest mud and loosest sand. When traction disappears and the trail turns to slop, the 540 Series is designed to keep you moving forward with confidence, thanks to an aggressive knobby profile that claws through soft terrain rather than fighting it.

• Extreme soft-terrain performance: The 540 is designed for extremely soft terrain, such as mud and sand.
• Self-cleaning tread: Wide spaced knobs shed mud quickly, keeping the tire biting even in the sloppiest conditions.
• Aggressive traction pattern: Tall aggressive tread pattern for increased traction in the nastiest conditions.
• High carbon rubber compound: Shinko tires feature a high carbon compound in a variety of models to suit all terrain conditions.
• Tire size: 80/100-21 front fitment with a 51M load/speed rating.
• Speed rating: Speed Rating: M (max 81 mph)
• Load capacity: Load Rating: 51 (max 430 Lbs.)
• Construction: Bias-ply tube-type (TT) design mounted position front, with a durable blackwall sidewall.
• Off-road use only: NHS (Not for Highway Service)
