225 was the std width, decided to stay with that as i'm still running a 8" wide rim on the front.  I'd heard people saying that going with wider front you could loose some of the handling.  Putting a larger width on front doesn't necessarily mean more grip when cornering, due to the cambering of the wheel when turning.  A wider tyre can also have other detrimental effects such as increased aquaplaning and friction (resistance) as well as increased steering feedback which may be good but up to a point. 
  
Just my opinion, it all personal preference
