Default 225/40/18 or 235/40/18

I have new set of Rota formula mesh wheels and i am trying to deciede on a tire size. The wheels are 18x8 with a 48mm offset and are going on a 02 WRX sedan. I can't deciede between 225/40's or 235/40's. I know am going with Falken FK451's or Hankook R-s2 Z212, just need some help with the tire size. Any help would be great.

I'm in the same boat, but my wheels are 8.5" wide +48, and I'll be getting the 235's. Keep in mind that because of the increased rolling diameter (.3) your spedo may be off a little, and because of the increase in weight at the outer edges you'll also lose some acceleration.
