In the past month I have replaced the original Goodyears on my C6. I'd driven them just more than 30,000 miles and the right front was worn to the point of being dangerous because the alignment was just a little out of spec. I went with Michelin Pilot Sports, mostly because everyone I know who has put them onto a C5 or C6 has been very happy with them.
The Goodyears on a standard C6 are D.O.T. rated for tread life at a value of 300. The larger and softer Goodyears on a Z06 are rated for tread life at only 220, if I recall correctly. The Michelin Pilot Sports in the standard C6 sizes have a D.O.T. tread life rating of 500. I hope to get 50,000 miles or so out of them.
By the way, everyone around here with a C6 is experiencing front tires wearing out much faster than the rears, and that seems to be counter-intuative. A recent discussion among my club members who have experienced this came to the conclusion that the C6 scuffs the fronts on turns much more than a C5 or earlier chassis. Although my front tires were worn to about 4/32's, my rears still had more than 7/32s left. When new the fronts supposedly had 10/32s, and the rears 11/32.
I just sold my used rear Goodyears to another C6 owner who suffered uneven wear on the rear due to bad alignment. He might be able to get another 15,000 miles out of them if he keeps the alignment adjusted. It seems alignment should be checked two or three times per year, if you want to keep your expensive tires wearing evenly.
