Tire question for 17x9 / 17x10.5...

I'm getting the Deep dish bullitt rims on my car, and I'm shopping around for tires.

I'm hoping that a 255x40x17 front and 285x40x17 rear will fit and look good, does anyone know if that is too skinny? I'm very aware that you can fit up to 315 on this wheel, but I'm not looking to further reduce the cars ability to drive in the rain...

Anyway, as far as the brand is concerned, I'm pretty sure I'm going with the following set:

Kumho ECSTA Supra 712 (Ultra High Performance Summer)
Specs | Warranty | Reviews | Test Results | Survey Results
Sidewall Style: Blackwall

Size:285/40-17
WR Speed Rated Price: $113

I have a question though... would there be any real disadvantage in getting the cheaper 255 front Kumhos.... I'm under the belief they will just handle a little worse, which doesn't bother me.

THANKS guys.... =)

Just for better handling? $50 is actually a big difference to me in the price, and I really don't need these things to handle well this is just a daily driver.
