No, don't go with that size, it's all wrong.

You can either go with 225/35/19 in the front and 255/30/19 in the rear, or 235/35/19 front and 265/30/19 rear.

For an E90 I would also get 10mm spacers for the front and 15mm for the rear.

The ideal rim specs for the E90 is around 8.5" ET30 front and 9.5" ET30 rear. Since your rims are 1/2" narrower than that, using 10 and 15mm spacers at the front and rear respectively would push them out to that of a set 8.5" ET31 front and 9.5" ET29 rear.

If you want to be conservative though I'd use 5mm spacers front and 10mm rear.
