The caps feature a glossy black finish and a removable top cover so you can add grease to wheel bearings without removing the wheel; the lug nuts use a one-piece anti-oxidation design for durability on aftermarket wheels. The set is designed for trailers, RVs, trucks and SUVs that accept the specified center bore and lug nut thread size.\u003c\/p\u003e\n\n\u003ch3\u003eWill these center caps fit my trailer wheels?\u003c\/h3\u003e\n\n\u003cp\u003eThe caps are made to fit a 3.19-inch (81 mm) outer diameter with an inner bore of 79 mm (3.11 in). They include a bottom lip that extends to 88 mm (3.46 in) and measure 96 mm (3.78 in) tall overall, so compatibility depends on your hub's bore and recess depth.
