Bullitt rim tire sizes closest to OEM stance

[Marauder731]

Was thinking about getting some Bullitt rims for my 04, wanted to go 18x9 up front and 18x10 in the rear. Wanted to keep the stock stance of the vehicle as far as the meat on the tires are concerned, just want to go a bit wider. Anyone know some good tire sizes that will be closest to OEM stance?

235/50/18 or 255/45/18 front
295/45/18 rear, better check offset of rear Bullits as a 9.5 widened marauder wheel are close to rubbing the shock with tire, I have to use a .25 spacer on the rear
