The BFGoodrich Mud-Terrain T/A KM2 (KM for Key feature: Mud traction and 2 identifying it as BFGoodrich’s 2nd generation KM tire) is an Off-Road Maximum Traction tire developed for off-roaders driving full-sized, lifted trucks that participate in rock climbing and/or other challenging off-road driving.
The Mud-Terrain T/A KM2 is designed from the mud up to overcome almost any obstacle in its path by combining more traction and mud-clearing ability than its predecessor with a smoother ride and less road noise than normally expected from an aggressive tire.
The Mud-Terrain T/A KM2 molds an off-road tread compound into a Krawler T/A KX-inspired symmetric design that features deep, self-cleaning independent tread blocks and linear transverse flex zones that provide the elasticity needed to allow the tire to conform to off-road obstacles when aired-down and driven at low speeds.
The tire’s internal structure includes twin steel belts and BFGoodrich’s Krawler TEK sidewalls and casing. Krawler TEK consists of three components that include aggressive sidewall lugs, cut- and chip-resistant sidewall compounds and BFGoodrich’s TriGard casing (three-ply polyester construction) with sidewall cords that are up to 33 percent stronger than the previous Mud-Terrain T/A KM tire.
These advancements allow for more bite and sidewall protection along with increased strength and resistance to bruising caused by rocks and rough trails. Single strand beads (a single strand of bead wire is continuously wrapped multiple times until the desired strength is provided) enhance the tire’s fit to the wheel to improve uniformity and ride quality.
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.
