Wheel dimension help needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a narrowed 9" on my 55 second series, the width from outer flange to outer flange is 58", after measuring I got 6" from the center of the wheel to the inner lip of the rear fender. So I would subtract 1.5" from that in order to get clearance once the truck is aired out.

If I was to run a 20x10" rim I figure I can have up to 6" of backspacing, if so then my offset would be +12mm? Is my measurement correct?

BTW: I use some information gathered from this site
