I went with 225/40/18 front and 255/25/18 in rear. Have rubbing in front. If you have the 2.5i sport you may need a an offset of around 45 to 50mm. The thing is in the shop now to see what can be done bc I really like the wheel/tire combo.

I recommend 235/35/19 in the front and 265/35/19 in the rear. Very common tire set up for staggered 19s.
