Has anyone built an interior tire carrier to fit a bigger tire? I'm mulling over ideas for how to fab one up to fit a 35-37" tire on end. In my case I'm looking at mounting it to existing bolt holes from the rear seat (removed) and rear seat belts. It would go behind the driver. I think it could be nice and sturdy mounting to the floor and bed rail. I can picture it in my head except for the part that actually mounts the tire, since this will need some slop to account for exact tire size, and I'd like the option to move from 35 to 37 in the future. Pics of anything vaguely similar would be helpful, thanks.
