This wheel is 8.5" +40, and can be clearly seen poking past the quarter panel, this has a hub to outer lip measurement of 67.95MM, or it sits inwards of the fender about 3mm of the 15x7+18 I suggested, and whattadobos suggested 17x9+20 @ 94.3MM hub to outer lip sits about 25mm, or 1 full inch past this.
