275/60R15 rear tires on the 67 rear end which includes late 66 axle width. Requires a custom 8x15 Rally II rim with 5-1/4" backspace, trimming the outside fender lip, and tapping the inside inner fender over frame in slightly so it sits slightly in from frame rail. Have my cars done and helped another half dozen or more club members with their cars and tires do not rub. Skip any of the above three requirements and you have to go smaller on the tire's section width. Doing the above allows almost 12" of width inside the wheel well and the 275 tire mounted on an 8" wide rim is right at 11" wide.
Believe one club member is running 255's on a stock 7" Rally II rim with the 4.25" backspace and the car has to sit a little higher in the rear or he gets minor rubbing.
Here's a photo of the current wheels on my car. While I was running the custom Rally II's, the car originally came with the dog dish hubcaps so I have went back to black 8x15 steelies with the poverty caps and the 5.25" offset. The car sits at standard ride height.
