I used this to fit a truck trailer spare tire and tire into a 6x12 truck trailer. The included bracket did the trick and after the first 5 hours of driving over varied terrain, nothing broke. As for the little features/things to note, it's lightweight, not steel so it won't rust. At first I thought it was cast zinc until I reread the listing and saw it said "aluminum"; It has a brushed finish that doesn't look like extruded/cut aluminum. The bracket comes with two screws of different lengths; the shorter one was just right for my 205/75R15. If you are using a very small/narrow wheel and tire you may need an even shorter bolt. There is nothing behind the head of the bolt to hold it in the square notch, this can make it difficult to tighten the nylon locknut onto the bolt. Other reviewers have placed a block of Styrofoam or wood behind the studs, but I found I could reach straight through the center of the wheel and over the studs to hold it forward when launching. A lock nut is not a wing nut or anything like that. So you need the right key. I don't remember if it was a 17mm or 19mm nut, but the square head wrench I had worked well with - so it's the usual lug size, not some random odd nut size I was afraid of. If you're using a long bolt or a thinner wheel, you might need a box or open-end wrench (or a deep socket) to tighten them, but I didn't. There are 4 holes in the bracket to attach to a trailer but screws are NOT included. The holes are just right for #14 screws, so I used 14 x 1 inch stainless steel screws to attach to a stud in the trailer wall. I was a bit nervous hanging like this over 40lbs but after the first 5 hours of riding over bumps I thought it held up great!
