Best fit on mine was a 15x7 4"BS, with a 235 tire. I tried 4 wheel sizes and 255 just never worked. The tire rubs the inner fender well toward the outer quarter when turning as the axle rotates at the center section. Tried trimming the opening lip which helped, but not with the inner well. You can get a custom wheel made with custom offset, but the outer lip would be shallow.
