I sorta agree, I think a good amount of it is also specific to a tires particular characteristic. 245/40 seems to be a pretty safe choice in all brands. I have ran 235 in the Z3 and SX2 and liked them in that size. Also keeping in mind that not all tires measure out the same to what is printed on the sidewall.
