This question goes for 4wd 2nd gen fronty. I am going to order a new set of rock crawler rims. Question is will the 3.75" backspacing be sufficient on a 15x7 rim? I am going to eventually get the revolving shack in which requires a max BS of 3.75". At the moment I am looking at getting super swamper tsl radial 30x10.5x15 or the 31x9.5x15. I am leaning to the first one, 30x10.5x15, because this on a narrow rims will allow more sidewall protection while aired down.

Any help on this will be appreciated, thanks in advanced.....

GOT BOULDER??????????

Doesn't the revolver shackles require limiting straps? So with either combination you should be able to adjust the straps so the tire just clears the frame, and body.
