Anybody running 17" Cobra Bullit rims on a Duster

The wheel pictured above is a 17 x 8" Mustang wheel w/ +30mm offset I've been using for a mock up in my '68 Dart. They barely hit the leaf springs on a stock A-body 8 3/4 housing even with the big bolt pattern swap and Dr Diff's disc brake kit. It's got a 275/40/17 on it and you can tell the sidewalls are bulged a bit. I measured it out physically and it was equivalent in width to a 255 series tire. I ended up purchasing 255/40/18's, they're just a touch taller, and I'm waiting for my 18 x 9" wheels. I'm going to use a +33mm offset for the front and +24mm offset for the rears with some sort of spacer (won't know how big of a spacer till I test fit it). As mentioned above, if you're going with an 8" wide wheel, I'd recommend sticking with a 245 or 255 series tire.
