Figured I would ask some of you guys for your expertise...

I need a winter set of wheels and tires for both my M3 (w/ brembo BBK; see sig) and my father's 2012 Maserati Granturismo S (285/35/20, 245/35/20). I have the following winter wheels & tires sitting in my garage from our previous e60 M5 & 2010 Carrera 4S Cab:

From the M5:
Dunlop Snow Sport M3 245/45/18 all around (wheels are similar to the ones here http://www.m3post.com/forums/showthread.php?t=174068, same brand but 5 spoke)

From the Carrera:
Pirelli Sottozero 295/30/19 & 235/35/19 (just tires)

Any input if either of these would fit on either car? If they are the Pirellis, what wheel size?

Your input is very much appreciated.
