Check my siggie.

Michelins, particularly the Pilot Sports, tend to have nice square shoulders and therefore are a nice and wide 245, whereas pirellis tend to be a bit narrow.

I can't say much about the Bridgestones since i haven't used them. I just find them too pricey and from what i've heard, too soft for the kind of driving i do. I don't track the cars and therefore don't need the super sticky stuff.
