My hitch rack worked fine with the spare. It was ~1" out from the rear tire and would pivot out of the way (opposite the door) to clear the door with plenty of room to spare.
I googled it to see if I could find a link, but gave up. I got mine at GI Joes (Pacific Northwest outdoor store chain) and paid $70 on sale a few years ago. Might want to look for that, or you can go w/the smittybuilt spare tire rack.
