Paul, several factors played into my decision.
1. I went with the Michelins for a couple reasons
a. I had the earlier versions of this tire on my C5 and liked them.
b. I wanted an "all Season" tire, and these Michelins were highly rated. Many of the RFs for Corvette
available are summer performance tires. I had Firestone RFs on, but driving them up to the untains in
the fall got a bit sketchy a few times
2. My local tire place said they couldn't get the rear tires I wanted, so, I ordered them from TireRack (they
were delivered in 3 days) and then had my local place mount and balance them for me.
I will say, that these new tires ride way better, are more quiet and make me feel more confident than the old Firestones. If you have an other questions, just let me know.
