Pro-Line BFGoodrich Mud-Terrain T/A KM3 1.9" Rock Crawler Tires were developed in cooperation with BFGoodrich. Pro-Line was given early access to the design of the just announced full-size BFG Mud-Terrain T/A KM3 tire and recreated it for the Scale Crawling community in 1.9” size! The Mud-Terrain T/A KM3 (Key feature: Mud traction 3rd Generation) is BFGoodrich's Off-Road Maximum Traction tire with aggressive tread lugs that bite into loose or muddy surfaces and climb over slippery rocks. Based on the BFGoodrich Krawler T/A KX symmetric tread design, the Mud-Terrain T/A KM3 features deep, self-cleaning independent tread blocks and linear transverse flex zones to provide the grip that you need to get over the toughest obstacles. Pro-Line’s re-creation of the Mud-Terrain KM3 comes in at 4.75" tall x 1.77" wide for the perfect balance of Scale looks and performance!
