The second set of Pirelli rears gave up after 6K (it was a fun summer running up and down Palomar mountain with the SLK guys, but I'm paying for it now). The original fronts are gone at 13.5k with 3/32" left. But its the rainy season and no sense in taking any chances. Put a set of Mich PS2 on. Hoping for better tread life without give up handling. We'll find out this summer.
