From the pic you posted, it doesn't look like your 225's stick out more than my Hankooks. You have 45 series, I have 50 and I know that effects "meat".
There is a chance it would work. But I wouldn't bet $240 on it.
rdss, you could always get the spacers when you need new tires, just make sure to buy 165s and stretch them. ;P

I try and stay away from the direction tires so I can four point rotate vs just front to back, just something else to think about in your tire search. Pirelli PZero's are pretty sick as well.
