I just need to put them on the rims I wont drive the truck that much. I got a good deal on craiglist for them. Iam trying to find 15x10 or 12' wide for them. The truck just sits in the yard till the weekends when I can work on it. Thanks

I just picked up a jeep xj with 33x15.50/15's on 8" wide rims....the guy wheeled it hard and drove it on the road too. They should be fine but may look funny like mine do.

I beg to differ to what others are saying. If its a true 15.50, I would never even consider putting it on such a narrow wheel. Especially if you drive it on the street as only about the center 1-2" of the tire would be making contact with the ground unless you ran with a very low air pressure, which brings up other safety issues.
But looking past this, this setup wont even work on your truck. The tires will rub like crazy in back. I have 12.50's on 8" wheels and they barely clear the springs. There is no way a 15.50 would clear.

Thanks Stuka I was thinking about That to with the B.S of the rim. How much B.S of a rim should I get?

Mine are 3 5/8". If you went with a 10" wide wheel, that would give you an inch more clearance between the tire and frame in comparison to an 8" wide wheel. A 12" wide wheel would give you 2" more clearance, assuming the back spacing is the same.
So here is the question, will you always run 15.50 wide tires? If so, then I would go with 12" wide wheels. That will give you 3.5" of "pinch". Or a little less than a 12.50 on an 8" wide wheel. 10" wide wheels with standard back spacing may work for you. But I personally have not tried a 15.50 on a 10" wide wheel on a J-Truck before. 12" yes, and I know that clears.
Or you could go with 2.5" backspace wheels, but you are going to add some stress to your bearings, and turning will result in your front tires having to roll, so if you have a front locker, turning will be near impossible without a full hydro system.

I know a guy running 35x15.50 sx's on 15x8 steel wheels on his XJ with 5" of lift and he has no problem. Tires dont roll over, and hasn't blown a bead yet, even at 8 psi.
He does have lots of rubbing issues though. :p

He must be mounting them himself. I worked at a tire shop for a while, and liability issues wouldn't let us mount a tire on a rim width not recommended by the tire manufacturer. A local tire or Jeep shop may do it for you, but a national chain probably won't. I'm having a hard time finding someone to mount a 255/55-18 tire on a 7.5'' wheel, if that tells you anything. And that wheel size is put down as minimum for the tire manufacturer.
