Little help?

Anybody know off the top of their head the diameters of michelin pilot powers (180/55 and 120/70) and dunlop 208 gp-a (180/55 and 120/70). I hear the powers are a good cold weather trackday tire and i need to know how much to adjust my ride height. Once it warms up I will be switching to pilot race m2 rear and s2 front so if you have those numbers too it would be much appreciated. thanks.
