I agree with the other guys, eventually you will need your spare tire. My B2 originally had a donut spare mounted in the back of the truck which wasn't big enough to match my other others...so I took it out and kept a full size spare in the back. It took up so much room that I grabbed a stock spare tire from the JY to put on my truck...until I saw what a pain it would be to put on. I eventually found a used rear bumper with a spare tire carrier built in. My 2¢.. keep your eyes open and find you a bumper with a spare tire carrier, saves space in the truck and keeps you from being stranded with a flat tire.
