Treadwear rating on the Bridgestone is 140.. significantly softer compound..
In my opinion this is the most important difference between the Sport package and the M Sport Package....on the 2009 model. Don't know if 2010, and 2011 are the same.

This is not correct for all 2009 M Sport Package cars. My 2009 M Sport came with the Bridgestones.
