Wheel off-set question for Gary

[EMD2006330I]

I have a E90 w/zsp. The stock wheels are 18 x 8 (front) and 18 x 8.5 (rear). I am looking at putting 19 x 8.5 on the front and 19 x 9.5 on the back. I am not sure what off-set to get. They have a 15mm and 40mm for the fronts and 15mm, 25mm, and 45mm for the rears. I don't have a good understanding of off-set, but I dont want the tires sticking out from the fender wells(at the top) and don't want rubbing on hard turns. Which off-set do you reccomend? I want to wrap them in 235/35R/19 up front and 275/30R/19 in the rear, what do you think? Thanks in advance!

The E90, from what we know so far, has higher offsets 35+ like the E46. I'd have to guess that the 40mm front and 45mm rears would be the closest of those listed options. 235/35R19 should be fine up front, but so far the widest rear we've fit is 265/30R19.
