Mr. Harris (or anybody else), if I go with 255 and 285 18's, would they be 30 and 35 or 35 and 40?
These (Pilot Sports Cup) are an option from BMW in the UK, and mine come fitted with them. I have swapped them out to preserve them for track events, etc. They are 245/35/19 fronts, and 265/35/19 rears.
