DIY Trailer Spare Tire Undermount for under $50! (Custom Superstrut Solution)

Learn how to build a custom spare tire undermount for your utility or cargo trailer! In this step-by-step DIY video, we combine readily available materials—primarily Superstrut (metal framing channel) and leftover hardware from this series — with a generic spare tire mount to create a high-value, concealed solution. This design not only secures your trailer spare tire beneath the deck, but it also completely frees up your cargo area. We'll walk you through the entire process, including how to measure, cut the Superstrut, and securely fasten it using leftover stud bolts to create a rugged mounting bracket. If you're looking for an affordable trailer modification that doesn't require welding and maximizes your usable space, this is the project for you. No more bulky tire mounts on the side or floor!
