I need to buy new rims for the k5. I have the stock rims on now 15X6. I want 15X8 but don't know what backspacing to run. I'm looking at procomps new rock crawler rims. Any help?
 
Stock backspacing on 15x8" rims is 4.125 or something very close to that. That is what I run on my truck and it works fine for me. Keep in mind the smaller the number BS you run will make life on your balljoints harder.

Well I'm in the market for 33X10.5r15 I think. My stock wheels are 15X6. The 10.5 won't work on those will they?
 
Ya, they will work on a 15x6" rim. 10.5's are narrow so they should work ok. I am running a 35x12.5 on my 15x8's. I know guys running 42" TSL's on 15x8's.

You can always take your spare tire rim assuming it is also a 15x6" and have the 10.5" tire mounted on it and see how it looks. If you don't like it then buy new rims. If you like it run it.
