I went through this last year. This thread should answer your questions.

In short sometimes are are differences between different car manufactures spec tires. In my case the ferrari one had a slightly different tread parttern and sidewall profile. Also the rear tires started out with 30% less tread!
You an go to the michelin website and look up each tire specs to see if anything is different. It won't be able to tell you if the sidewall profile is different though.
