Features & Benefits

Snow Groove Technology™, patented saw-tooth technology traps snow in the tread to provide superior snow-on-snow traction.
Aqua Vac™ channels, uniquely shapped deep center grooves improve the tire's resistance to hydroplaning.
Secure-Grip™ all-terrain design, specially designed 5-rib all-terrain pattern provides greater off-road driving capability and improved wet/dry traction.
Micro-Gauge™ zigzag sipes, smaller gauge sipes in all tread blocks, provide increaased vehicle stability and control, while reducing stone retention and drilling. Zigzags create more biting edges for optimal wet/dry traction.
