Anybody ever tried this?
That's basically what the Bestop tire carrier for the TJ is. The advantage is it allows the tire to swing w/ the tailgate.
If you fabricate something yourself, keep in mind that it's not so much the weight that's an issue, it's the cavitation - the back and forth bending. Sort of like how you can stand on an empty beer can, but if you bend the sides even a tiny bit, it won't hold any weight at all.
It's why you need to make sure your tire on the stock carrier isn't vibrating at all. Like PhulesAu, says, hockey pucks or spacers or whatever, to keep the tire still.
