15" rims & drop spindles = limits on backspacing. 3.75 - 4.0" is typically max you can go w/o contact issues @ the a-arm when turning. A mild shave of the ends of the lip (near the BJ) helps w/contact issues as well.

Common steel wheel/15" set-ups are:

15x6 front w/215-75's & 15x8" rear w/255-70's
15x7 front w/225-70's & 15x8" rear w/275-60's
15x7 front w/215-70's & 15x10" rear w/275-60's
15x8 front w/245-60's & 15x10" rear w/295-50's

The combo's are typically based on personal preferences as well as how low the truck is (so rubbing is limited).

Below is 6/8 drop on15x6 w/215-75's & 15x8" w/255-70's. It had mildly massaged a-arm lips.....
