I have 35's with steel rims and that's my max. I can't imagine hoisting a 37+ up there by myself. On my K5 I have an interior carrier, so I just need to get it onto the tailgate and then it will roll. With my Jeep, you need to get it up and then control it enough to align with the lugs, which is a fair PITA. A better design would have some sort of protrusion to hang the tire on while you got it aligned instead of having to get the lugs lined up.
Maybe just get good with patches and stitching and avoid all this pain...
