fyi, I put a 295/30-19 tire from my E46 M3 CSL wheel on the M2 rear and it seems to clear fine. So... I just need to determine if a 275/30-19 tire will clear in the front. Thanks in advance for any shared experience... yo, Tirerack dude?
Here's a pict of 295/30-19 tire mounted on 10" CSL rim on my E46 M3 as requested... (one of the reasons I put a larger tire on this daily driver rim was to reduce the car-wash curb-rash). Since then, have found car washes with the new conveyor belt transport (GREAT improvement).
