So confusing about sizes recently, I'm having 19*8.5, 19*10 with 235/30/R19, 265/30/R19 tires in my garage. But my F30 OEM tires are 225/45/R18, 255/40/R18. I really don't like the thin tires, that's why thinking about go get a set of 225/40/R19, 265/35/R19 for balancing thicker tires I want and also the 19*8.5, 19*10 rims width.

Is 225/40/R19 too small for 19*8.5?
Does 265/35/R19 perfectly fit to F30 without any installation problems?

Any other better recommendations ?
