The Open Country M/T is legendary for durability, off-road performance, long tread life, and an aggressive tread pattern. It's designed to help trucks work hard on pavement, then work just as hard when roads are muddy, snowy, and rocky—or when there are no roads at all. The aggressive tread design delivers excellent off-road traction while maintaining great on-road performance. The open, scalloped shoulder blocks help eject mud and snow through the open channels, further maintaining the grip in those conditions.
