If it was me, since you've gone to a non-staggered wheel size, I'd go to a non-staggered tire size, but buy one size bigger tire: 235/40R-19 front and rear.
You could certainly stick with the original 225/40R-19 size as well.

An even better place to ask this question would be the 3/4 series F30 tire and wheel forum. Click on the 4 series at the top of the page, then look down the page to find the wheel and tire forum.
