The Road Venture MT51 is Kumho's Off-Road Maximum Traction tire designed for the drivers of Jeeps, pickup trucks, full-size SUVs and dedicated off-road vehicles looking for a tire tough enough to handle extreme conditions, yet doesn't completely sacrifice on-road comfort and driving enjoyment.Utilizing an off-road ready tread compound molded into a symmetrical tread design, the Road Venture MT51 is engineered to take on the toughest terrain. The wide tread blocks are strategically shaped to combine capability in mud and on rock with on-road comfort, and the stepped, three-level block edges maximize off-road traction. Alternating, scalloped outboard shoulder notches combine with the aggressive upper sidewall design to seek out any available grip in loose surfaces, in addition to providing protection from punctures. The deep, circumferential grooves feature a zigzag pattern to increase mud traction and help eliminate stone retention, and in-block sipes create additional biting edges for improved wet and light snow traction.The internal construction of the Road Venture MT51 is designed for strength, durability and on-road civility. The two-ply (three-ply in load range E sizes) polyester casing supplies added puncture resistance, in addition to improving ride quality. Two high-tensile steel belts are reinforced with a jointless nylon cap ply designed to enhance belt durability, improve uniformity for a smooth ride and aid high-speed handling, while the advanced bead contour reduces movement of the bead under load for better ride comfort and increased steering response.While Off-Road Maximum Traction tires, which are often called mud tires, are branded with the M+S symbol and able to churn through deep snow, their typical oversize applications and the absence of snow-biting sipes in their large smooth lugs can challenge their on-road wintertime traction on packed snow and icy surfaces.
