Introducing Tie Down's Aluminum Diamond-Plated Trailer Fenders — precision-engineered to deliver superior trailer wheel protection and durability. Made from high-quality 12-gauge (0.08 in.) aluminum, these fenders are built to withstand harsh weather and marine conditions while maintaining their high-grade finish. Designed for optimal compatibility, these fenders are intended for trailer wheel assemblies with an overall tire diameter of approximately 18 inches. Typically, this means a 15?inch wheel paired with the proper tire profile will achieve the correct fit. For those using 13? or 14?inch wheels, please ensure the tire selected provides an 18?inch overall diameter to guarantee compatibility and proper coverage. With easy customization options to suit a variety of mounting setups, these fenders are the perfect upgrade for both single and dual axle trailers. (Note: Mounting brackets are sold separately.)
