You just need to add in spacers under your existing tire carrier. Cut up some 1x1 square (can get it from metal mart) and you should be in business. I think that's all I used if I remember correctly.

The trick to choosing air pressure is to realize that it's the air volume that supports your rig, not the pressure. A large tire holds more air volume at a given pressure, so you reduce the pressure until you get the right volume. Your shop probably put 40 psi in your tires to make sure the beads seat. I'd guess 28 or so would be more appropriate.
Get a piece of chalk and draw a line across your tread (shoulder lug to shoulder lug), then drive a few feet. The lowest pressure where the entire chaulk line get's scrubbed is you lower limit for street driving and gives the softest ride. The highest pressure where the entire line gets scrubbed is you max street pressure. This is good for low resistance on the highway, but will make for a rough ride. Find a compromise between ride and resistance between the two pressures.

As for the tire hitting the bumper, If moving the tire away from the Jeep slightly would help you could knock the studs off the tire carrier and install longer ones. If it's only a touch too big then letting some air out of the spare might get it to fit.

Aside from that, buy a spacer or get someone to build one for you.

well i finally got my spare tire on last night but i cheated...i just deflated the tire so it fits..i will probably add longer studs and a spacers on the weekend to actually make it fit better...i notice that when i had the tire on and i open my tail gate there seemed to be alot of stress on the tail gate...is that going to be ok...how big of tire do u guys think is the max a stock tail gate can handle?

keep in mind that adding a spacer will increase the weight on the tail gate (increase in leverage). i would say that 31" spare would be max but hey that is just my opinion. i had a 32" on my stock gate and it really took a toll on the hinges after a month or so. the tail gate was not made for that sort of stress especially when bouncing down the trail. if you go wheeling anytime soon i would just throw the spare in the back tub and not worry about it. you can fit a 36 back there with no problems ~ just take out the seat!

CornJeeper is right. The 32" tire will start to fatique the hinges and sheet metal on your tailgate. A bumper/carrier combo should be on your wish list. You'll need a stronger bumper to act as a recovery point, anyway. <g>

In the meantime, you can strap the tire down in the back of your Jeep (use the seatbelts, they should be strong enough).

As for Greg W's suggestion about the 1" extension, I don't think it would apply to your setup since you have the TJ bumper. With the YJ bumperettes, the larger spare could hang down between the two bumperettes. The only issue with the 32" tire was the extra width so you had to move the mount 1" further out so you could thread the lug nuts onto the studs.
