My coach has black rims, and I wanted to put black hub caps with chrome lug nuts. My lug nut will only alow push-on caps. The problem is that the front and back hub cap holes are 1 11/16 in (33 mm), while the lug nuts are(1.5) 32 mm. In other words, the hole that slips over the nut is larger than the chrome cap of 1.5 inches. When I drive down the road, the cap vibrates and pushes the push-on cap out, which inturn alows the hubcaps to fly off. Any idea on what I should use to stop that?
