George,
I have three-piece HRE 17x9.0" front wheels with 245/40-17 tires. My wheels have 22mm offset and the tires rub very slightly on the passenger side inner fender when the steering is at full lock towards that side. I have no rubbing on the outer side at all, although my fender lips are rolled. I should also mention, my tires are Hoosier R6's, which are wider than most 245/40-17 street tires.
To the best of my knowledge, any of the Boyd Coddington Campi clone wheels use the same offset (see box label, below), regardless of width or diameter. I say "any" of the Boyd Coddington Campi clone wheels because they make a few (slight) variations of that wheel, for a few different Pantera parts vendors.
