SCORE 2019 Off-Road Tire Guide The Latest Rubber For Off-Road Adventures By Mike Vieria Tire companies have made great strides in creating treads and compounds that can grip everything from sand, dirt, rocks and even pavement. We’ve gathered some of the latest off-road tires that range from the most hardcore Baja race designs, to moderate all-terrain tires. Depending on your vehicle and the type of driving you do, some of these tires can blur the line between their capabilities on the highway, and at speed on the Baja desert. BF GOODRICH Tires 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 CoreGard 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. BF GOODRICH Tires All-Terrain T/A KO2 The All-Terrain T/A KO2 uses race-proven technology to deliver exceptional toughness, tread life, and traction in the toughest conditions. The KO2 uses CoreGard Technology developed in BFG’s Baja T/A KR2 race tires to improve strength and resist bruising. Tread rubber is optimally blended to reduce chips and tears on gravel, while a new footprint shape and interlocking tread blocks provide more uniform wear. Stone ejectors reduce drilling to the tire by pushing objects out of the tread and raised bars in the shoulder help release compacted mud for better traction. Available in various sizes for 15” to 20” wheels. TOYO TIRES Open Country M/T R The Open Country M/T-R is designed to deliver maximum traction and durability for off-road racing. It has won both the Baja 500 and Baja 1000 races, along with multiple SCORE-International Off-Road Championships. Hook-shaped center tread blocks deliver optimum traction in sand and rocks, and the tread wraps onto the sidewalls to provide grip in deep sand, and to resist cuts.
