I did it when I bought my take offs, The air was out and the bead broken so they were soft and took up less room though. The seat was definitely out and I had unmounted my stock spare so we could mount one outside.
I was able to fit 5 and a subi tire in my JLU so putting five into a 2 door dont think thats gonna happen unless you install one on the spare tire mount and run four inside. that should be ok
