19 x 9.5 et33 10 et38

I know this topic has been covered in multiple sections, cant find anything for these specific fitments. I have 2011 335i x sedan, I am going to purchase the VMR vb3's in 19 x 9.5 et33 10 et38. My question is related to tire sizes. Of what I see, most people run 235/35/19 and 265/30/19 for tires. I would prefer not to stretch the front tire that much and would rather go with a 245. With the x-drive and having to maintain rolling circumference, what should my tire sizes be if I wanted the 245 in front?

Thank you for any help you can offer.
