• Four Circumferential Grooves: Efficiently channel water, slush, and snow away from the contact patch to resist hydroplaning
• Serrated Stability Rib: Center rib enhances straight-line stability and steering response
• Split Offset Shoulder Blocks: Large outer blocks with plow edges improve cornering grip and lateral stability
• Tapered Evacuation Grooves: Specialized groove geometry accelerates water and slush expulsion
