Don't listen to the people telling you not to get new wheels, especially @
Tcoat, the stock ones are ugly.
Preferences in wheels looks are personal, but if you are looking for a wheel/tire combo that will be the same weight, or maybe even slightly lighter than stock, take a look at the Enkei PF01 in 18x8. It will take a 225/40 tire and looks very snazzy.
I have it in 18x8.5 with 225/40 on it right now, but I got 8.5 because I will be going wider for the track. For commuting you should be fine with 18x8 and 225/40. There are literally tons of tire options in that size.
