scott,
I'm kinda stupid to even mention it. The only reason is a while ago I was in your same shoes and ended up doing the math.

I believe it's 2% on Front and 1% on Back since the rears overall dia. is smaller. I'm just reassuring people that yes it's perfectly within tolerance. Actually, 225/45-17 is a stock tire size.

19 x 25.4 = 482.6

(F) 235 x .35 = 82.25
82.25 + 482.6 + 82.25 = 647.1
(R) 265 x .30 = 79.50
79.50 + 482.6 + 79.50 = 641.6

17 x 25.4 = 431.8
(S) 225 x .45 = 101.25
101.25 + 431.8 + 101.25 = 634.3
