Federal has added the Couragia F/X tire line to its Couragia Adventure series. Performance characteristics of the asymmetrical-design tire include short wet and dry braking distances, precise handling and high cornering responsiveness specifically tailored to meet the requirements of high performance luxury SUVs, the tiremaker said. Additionally, the tire features a scuff rib to protect the rim from damage, and stiff, interconnected blocks to increase the amount of edges in the tire contact patch. The F/X initially will be available in sizes for 17- to 20-inch rims, with V-, W-, and Y-speed ratings.
