A No-Spin Zone Today’s Off-Road Tires have a Baja influence that has improved both traction and durability By Mike Vieria Off-road tires have come a long way since the early days of competition, with new innovations in tread design, puncture resistance, and longer tread life as a direct result of manufacturers’ participation in Baja racing. As off-road tires improve for racing applications, the technologies are also used in tires designed for off-road/street use. For the average off-road enthusiast, it means more capability for their vehicles when driving off-road, but with better fuel economy and less noise while driving on the highway. To showcase some of the latest off-road tires, we gathered several off-road racing tires, and dual-purpose tires from various manufacturers, many of whom participate and sponsor SCORE racers and turn their knowledge of Baja racing into better tires for enthusiasts. BFGOODRICH TIRES BF Goodrich Mud-Terrain T/A KM3 The BF Goodrich Mud-Terrain T/A KM3 is the next generation off-road tire with improved traction and strength for conquering extreme conditions. It has an advanced deflection design to help guard the upper shoulder area against snags and splits, race-proven Coreguard Max Technology and Traction-Armor Sidewall Sculpture to prevent sidewall splitting and puncturing, and Krawl-Tek compound to enhance grip on rock and other slick surfaces. The Terrain-Attack tread design uses massive tread blocks for maximum grip from any angle in mud and loose soil and Mud-Phobic Bars release compacted mud to maintain traction. A Linear Flex Zone allows the tire to flex and envelop objects in aired-down driving situations.
