I am looking at getting a new set of wheels. Black Rockcrawler's in 15x8 is what im looking at. What I am concerned about right now is getting the correct back spacing so that my wheels will fit correctly. Right now i have 31x10.5's on my truck and they are fine on the stock wheels, but in the near future I will be going to 33x12.5's. I read up on R.B.'s website about offset/backpacing, etc. I am still confused. Im pretty sure that right now my wheels have 4.5" of backspacing. I am thinking that I probally should get the new wheels in 4" of backspacing, so that the additional 2" of width will have clearance. Does this make sense, should i go with 4'' of backspacing? Also will the aditional backpacing make the 33's rub on the valence and the quater panel? FYI my rim to fender distance is about 16.5".

Here is a picture of my current setup.



One last thing, the tires i got now should work ok on the new wheels before I get 33" tires, right?

 

I'm not sure they're available with 4" back spacing, but you could definitely get them with 3.75". That's what I have with my 32"s and they work great.


Yep. 15x8's are great 'cause you can fit just about any tire from 31x10.5 to 38x12.5.

 

Do you guys think I could fit 33" with just a 2" BL and BJ spacers?

 

Yep. In the photo below Ace is running 35"s with a 3" body lift and BJ spacers. (He also has fiberglass fenders, but that doesn't really make much difference. The bigger problem is with the pinch weld at the back of the wheel wells).

I have 32"s and BJ spacers (no torsion bar cranking) and would easily fit 33"s with a 1" body lift.

 

SWEEET!!! Just what I wanted to hear!!

So what is this pinch weld thing your talking about?
