they were sold . i hgave a set on a callaway snt475 i just bought and was wondering how one would tell when they were made. or when they were last made . they are in good shape ,no weather cking . but they have all the traction of a greased pig .. are their people interested in these for show cars?if so i would rather someone get these instead of just wearing them out
All tires have a date code on them. You'll see a 3 digit number in a circular or oblong spot. The first digit is the last digit of the year and the other two digits are the week of that year. So (328) would be the 28th week of 2003. Or if really old tires, 1993.

Hmmmmm...interesting. When I bought my Z in 2001 it had a new set of GS-Cs on the front. They look almost as fresh today as they did 12-13,000 miles ago, and stick like glue. OTH, the Yoko AVS's I put on a couple of years ago are hard and slippery even though they have most of their tread left. I'd put another set of the GS-C's on if they were still making them. I am thinking of taking advantage of the price on a set of Sumitomos so they'd match, though.

Though 2000+ tires have a 4-digit code. And tires from before ~1990 will not have any DOT date coding.
I've got a set of GSC's on my 92 with 37,000 miles. They still stick and work good. Looking to get some other tires so these don't get worn out.
Give me a break
You're telling me 16 year old Z rated tires "still stick and work good". You ain't tryin' hard enough, because those tires are PLASTIC.
His GS-C's could be as new as 2000-1 or so. I believe that's around when Goodyear dropped them in our sizes? Still, I imagine when he replaces them, he'll realize how they didn't actually work so good.
i know the gsc-s that are on the callaway snat475 i just bought are hardley glue. more like slicker than snot on a door knob. they suck.with the dg-3s gone whats best in our sizes. i got to get these thing off the car.

I bought my rear GSC's in Sept 2000 from Tirerack and they were on special/clearance due to Goodyear discontinuing them.

Tires are good for about 5 years according to the manuf.
After that they turn to stone
That means the newest GSCs are 7-8 yrs old
It doesnt matter how you try to rationalize it they are not safe -period

To begin with, it's 10 years, not 5 years. http://www.coopertire.com/html/pdf/S...ulletin112.pdf http://www.michelinman.com/media/en-...l_Bulletin.pdf
But it also depends on how they're stored. I've autocrossed on 20 year old Gatorbacks and they had plenty of stick. But they were stored out of the sun and away from electric motors for 98% of those 20 years to keep the ozone from attacking them. Not everything is black and white.
If I had been daily driving on them for 10-12 years, I'd agree with you...but then again, I would have worn them out after 2-3 years. I rarely even run the tires as my autocross tires stay on the car a majority of the time, even then I just drive around town. About the only time the GSC's go on is for the SGC gathering in Nov, the rest of the time they are stored properly. When they start to lose even the slightest amount of grip, I'll know.

My experience disagrees with that. Mine were put on in 2000 or 2001 and are still soft and sticky. They don't show any signs of hardening. The hardening comes when the tread is worn down to the depth where the compound changes to preserve the tire's longevity for general use (not racing).
