The new Maddog radial has a fairly aggressive tread pattern, but doesn't have an overly knobby tread that sticks out and catches sheet metal. The center tread blocks have siping in them to help during wet and icy road conditions. We tried out a set of 38.5x14.50R16 tires, but other sizes should be available by the time you read this. We put the tires onto some old Weld Racing wheels. Weld is not currently making wheels for the off-road market, but the ones they used to make were bitchin'.
