This spare tire mount fits perfectly on my 3" x 5" boat trailer frame and can mount my 15" spare tire (6 lugs). The photo I took was taken after I put the protective cover on (sorry). I just have two concerns: 1: the lock washers are awkward and difficult to install (don't know why they aren't pre-installed) and 2: the lock bolts don't have standard threads so you can't use eye-tire retaining nuts (and can't use tire retaining nuts as spare nuts I'm deducting a star for these reasons. I'll have to see how the mount holds up to the elements over time. I placed it far enough forward that it wasn't in the water at all when I launched my boat and lifted.
