Most of the above posts say it all about those crappy tires. 
I am surprised that there haven't been multiple lawsuits against GM because of the dangerous aspects of these tires after 5+K miles. I think GM using Michelin on the later Zs and C7 says it all.

The fuuny thing about this forum is that when somebody with major credibility speaks nobody says nothing about his view on the subject. Me on the other hand who has zero cred only post to what i think may or may not be helpful on a subject. Bill Dearborn gives basically a glowing review for the GY's on this thread and not ONE of you guys dare say anything bad or negative about the GY's in his post. Me on the other hand who is a nobody I ask a question and everybody comes out of the woodwork slamming the GY's. Not so when Bill Dearborn speaks on the same topic. A lot of two faced people on this forum. I think half the people chime in on subjects to bad mouth the product just because everybody else does.

You were the OP. So, you got the responses.

Oh I'm not complaining I knew these would pretty much be the answers but it would have been interesting if Bill Dearborn started this thread instead of me. Ok lets hear some more feedback on the GY's as this was the purpose of the thread to begin with.

yeah that about sums it up and I would tend to agree with your Original Post and Bill's post 
In my experience going by hundreds of posts, the Super Car tires are for a specific application....
Hot weather, Track use, Soft grippy rubber compound with fast wear and suck in low temperatures.
Ride rougher than most tires, noisy and harden quickly.
On the other hand, the OEM GY's GS-2 tires on my 09 Coupe w/ F55 are nothing like that compared to all the bad reports on OEM GY's.
At 14,000 my OEM GY GS-2's looked new, but I replaced them with Michelin A/S ZP tires for cold weather in Spring and Fall.
Yes the GY's lose noticeable grip in colder temps but that's a given
After 2,000 miles with the Mich A/S I can say they ride better and grip great in all temperatures.
But, the ride is only slightly better .. noticeable,. but not by much, and as far noise, they are quiet but no quieter than the OEM GY GS-2 tires.
On a newly paved Highway, the GY's were dead quiet while the Mich are quiet but,have a slight singing sound which I'm sure is from the Tread design.
I can see why the PS2's etc, are quieter with a smoother tread pattern.
IMO, there is definitely better tires out there, but the GY's serve their intended purpose.
They're just not the best choice for the majority.
Of course there are those wanting a tire that grips like glue but then not happy when they wear out too fast.
There are better tires that do grip great with better wear, but it's all relative.
IMO, kind of hard to have extreme grip and long wear in one tire

My '06 lasted exactly 14,800--which is when I traded it in after buying a new set of Contis. The treadwear is what, 200-220, and they weren't kidding. No complaints about the tires--crappy in cold weather, but all summer ultra high performance tires are. Never in snow, so didn't have that bad ju-ju. The new F1 EMTs have a 300 treadware, so I would expect 20k out of them. A 1/3 improvement in tire life isn't bad. The Contis had a 320, as I recall, but never saw them on the car. The dealer put them on my '06 after I got the '13. Price/performance comes into play. You can get just as good, or better, runflats for less money, and much better non-RFs for much less. But as OEMs, I found them to be decent.

Look at NHRA when top fuel and funny car had to use GY and still do .The amount of cars that were lost to the GY tires were extensive .
Now GY fixed the problem and they don't wreck as often.
If their was another thread about GY no matter who wrote it I would have flamed it also ,not all of us pay attention to all the threads on here all the time.Who remembers the gatorback tires they sucked also

Not sure who this Bill Dearborn is and I did not read his article! However, in my experience, the GY tires are just plain expensive garbage! I do not have one good thing to say about them or run flats in general. Did you note that the Tesla S does not come with run flats or an on board compressor, etc. Smart folks to not put junk on their mighty fine electric car....

Over many year with the Goodyears, I've been very satisfied with them. I don't agree with the complaints about them. I've not had tread wear issues, nor noise issues, nor hard riding issue and on top of that I've also had the Michelin Pilot Sports which were not run-flat and Goodyears which were not run-flats.
I'm perfectly satisfied with Michelins, but I'm also perfectly satisfied with the Goodyears. Clearly, the Goodyears which provide the best all around service and tread life are the those that are standard on the coupe and convertible. The Z51 package or the GS changes the equation, but again I've still been very satisfied with the Goodyears. Currently, I have both brands since my 427 Convertible came with Michelins, and my '09 convertible has Goodyears.

Sounds like a few of you took quite a bit of offense from my comment. Must have hit a nerve? Don't get your panties in a wad and play the immaturity card. I've been driving high hp cars "on the street" for about 15 years now. Btw my vette is not the fastest by a long shot so save the advice.

Yeah Skyline and I understand how airline pilots always have to have the last word to establish their authority. It's tough to direct a bunch of flight attendants. Keep speedin dude. To each his own.

I've replaced my front F1 Supercars twice and the rears only once. I now have 42,000 miles on the vehicle and just switched to non-runflats. I'm running BFGoodrich Comp 2's in stock sizes.
I never had a problem with the GY S/C's at all, except their price.
I never had a problem hearing my radio like so many other posts I've read. Actually, they were never, ever noisy. They always gripped like an SOB and my G meter has often gone over 1.0 in the back roads here in WNC. (I don't drive it in winter).
Probably my only beef:
When I ran the quarter mile at Bristol, I had a difficult time getting them to hook up and my 60' time in 6 seperate runs was never less than 2.4 seconds (which is bad for a C6). My best time with that 2.4 60' was 13.0 at 113 mph. My launch technique could use some work...
I've also been told running 1/4 mile runs is a waste of time with ANY street tire.
My car is a 2008 convertible, MZ6 (manual with Z51 option) that I've had since new.
