Greetings of the New Year !!
I have been watching threads like this one since I too am about to replace my 1st set of factory tires. My 2007 C6 has the Z51 package, thus the supercar tires. Even without track time, they are looking like they will need replaced this spring and with only 8600 miles currently, I'd guess they won't go 12K in the end.
I have considered the GY GSD3's, I went through two sets of these on my 2002 CLK55 AMG Mercedes. I only got 12K out of each set, and found that a little disappointing. I had picked them for the V shaped tread pattern that was similar to the AMG's factory Michelins (they changed the thread pattern on the pilot's) and I put them on at a time when I was very disappointed with the way Michelin Teams messed up the Indy F1 race (OK, I'm still not over that one).
The GSD3's were great handlers even in the rain. They too were noisy near the end of the life cycle, I'm guessing this must be common as the thread depth lowers. I also drive most of my daily commute around Indianapolis on the 465 interstate, here the concrete highway (not black-top) is very noisy.
Is it a simple fact the if I am going to play...I'll have to pay...to the tune of $2,000.00 per year for tires...I plan to drive this wonderful car 10-12K /yr. March -through- November (and on days like yesterday...68 degrees here).
I have been considering a second set of wheels, for a non-run flat....peak of summer tire, that I hope to take on the car to the track 2 to 3 times a year.
Suggestions are welcome.
.... I should add, that I am curious about anyone who is currently running the Firestone Wide Ovals on the street.....since I may have a prefered pricing option here as the daily driver set.
