If you have a 99 or up car you can do a 335/30, they wont rub or stick out with the wheels you have, But they are very exspensive!!!! I had them on my 98 but when I lowered it they would have rubbed the inside and outside, but on my buddys 04 they fit perfect and his was lowered 2" (WIDE.) Looked awsome from the rear of the car.
315s is a perfect tire though, they can be had for a low price depending on brand, but 335s are sweet.

I just had 315/35/17 put on about 2 weeks ago with the deep dish 17x10.5 wheels and it looks amazing. Check my profile for pics if ya want. Glad I went with 315 too....bad ass.

Yeah mine are actually just a slight shade lighter than my stock ones. But like said above, nobody has noticed it except me. And its not off enough to make it look bad.
