I just found out that I can get 15x8" Craiger black rims for $160.00 shipped. I had no idea they were this cheap so now Im forced to buy some lol.
I have a 97 Jimmy 4wd. I was looking at there 15x8" 4" rear spacing 5x4 3/4 lug pattern. Is this good?

 

they'll work for ya. You might run into rubbing issues when you go with bigger and wider tires though. Just be prepared to have to trim fender or lift more to clear a 10.5 with that 4' of backspacing.

 

I plan on running 31x10.50 tires. I just installed my 2" body lift today and I plan to crank the keys an inch. Will I still have rubbing issues?

 

With a 2' body lift you shouldnt have any problems. The only way I see you catching fender is full lock + suspension compression. But you should be ok.

 

great, Thanks!
I noticed your rims look identical to the ones I want. Are they Crager rims? Did they come with the center caps?

 

They're Pro Comp Xtreme steel rims, supposed to be lighter weight than the Cragers. And the chrome center caps and lugs do not come with the rims.

 

With only 4" of backspace plan on replacing front end components on a fairly regular basis if you plan on doing some offroading now and then.

 

I wouldn't say 'regular' basis....sure more often than if he had stock rims...

I've had 0 problems (short of a power steering groan, which Hanr3 told me how to fix ) with 4.5' of backspacing and I frequently find myself off the pavement

But yea, stick as close to stock as you feel you can while still getting the look you want, but be prepared for parts to wear out, no matter what you change. Anything modified past stock will be bound to wear something out prematurely!
