I am considering moving my spare tire (33") into the cargo compartment. I get tired of having to move the spare out of the way every time I want to open the back. I have seen several threads about putting it on the driver's side and mounting it to the existing brackets for the tire jack and such. This looks like really flimsy metal and I am doubtful that anything that you attached a 50 lb tire to at that spot would hold in a collision. Can a person build something that attaches to the floor, and if so, will is withstand a sudden forward collision. Yeah, I know, "use the search"...but you probably don't have dial-up..
