There is alot more to this. The wheel probably won't hit at all but you need to be concerned with tire rub. This depends on what tire size you run and if you have stock rubber control arm bushings or heim joints or a watts link or panhard bar to prevent side movement of the frame and body. Also it matters how much roll stiffness your swaybars have to prevent body roll.
I usually try to obtain 1" clearance between the frame/wheel tub and the inner tire bulge. The outer tire bulge can be much closer to the lip on the fender- like 1/4" or less.
Picture a right hand turn from the drivers seat. The body leans to the left with the left side moving down and left in relation to the tire and the right side moving up and left. On the right side the clearances get wider at the frame and the body moving upward keeps the fender from rubbing. But, on the left side the frame moves closer to the tire. Especially at the top of the tire. More roll stiffness and less compliant bushings allow tighter clearances.
