Best tire combo for wider aggressive look

I have been doing some research on popular tire combos for my sport package 370 with the factory 9 inch and 10 inch rims. I believe I've narrowed it down to keeping stock size up front with 285/35/19's in the rear, or 255/35/19 up front with 295/30/19 in the rear. The only thing I'm worried about with the second option is considering the diameter of both tires are smaller than OEM size there will be too much wheel gap showing. I'm sure it won't be a horrible amount since the difference in diameter is negligible. I would consider a 305/30/19 which will be a larger diameter but I'd say that's kind of pushing the limits of the OEM rim and don't know if I can match up a size in the front well. Any opinions would be highly appreciated!
