I searched online and through the forum but nothing really helped me. No lift or leveling kit on my 1999 silverado ext cab short bed. I want 15" cragar rim. I know that will fit, but will I be able to put a 15x8 w/ 4.75" backspace on with a 31x10.50 bfg a/t without rubbing? I want them to stick out as far as I can without rubbing and I know that a 4" backspace is stock.

thanks

hopefully this helps. looks like tho, you might be limited to the 4.5" backspace.

 

very helpful, thanks maxx

 

Stock backspacing is somthing like 5 or so. I would think you should be fine running that setup
