Hubcap Mike's solid stainless steel Pop-On racing disc wheel covers are great for trailers and fit standard steel wheels and you just pop them on like any hubcap.
Our solid aluminum Screw-On racing discs wheel covers are also great for vintage trailers. Screw-on means that these wheelcovers are screwed into the wheel and work on most any wheel that uses the same size tire as the size racing disc. Don't worry, we have a link on the screw-on product page with complete instructions how to install them!
