A spare tire carrier with mounting hardware for the off-road trailer.

An off-road trailer goes where punctures happen, and a trailer flat a long way out is exactly as trip-ending as a vehicle flat. This mounts the spare on the trailer, so it is not taking up bed space or riding loose.

If your trailer's bolt pattern matches your tow vehicle, the spare on this carrier covers both — which is the argument for matching them when you order the trailer.
