Well, the GSD3 tires are in stock again after a hiatus of some 10 months or so. The are $205 each and made in, (get this) the USA. [For those of you just joining us, the USA is a place where stuff used to be manufactured. It was a wonderful setup which had the desirable benefit of providing a living wage to the citizens. A living wage, for those of you unfamiliar with the concept, is a wage which provides enough money with which to support a family without borrowing any money or using credit cards, meanwhile putting money in a savings account for use during unforeseen emergencies. Healthcare was paid by the employer, and roughly 80% of the citizens had a savings account which could see them through 12 months of unemployment.]
These are the only tire available in the original size and performance category. Whatever else is available is either an offshore bargain brand or a low level all season tire from a premium brand.
you would be well advised to buy these while they are available, even just to have them in stock. As soon as they are discontinued, their value will increase considerably. This is likely the last real performance tire ever to be available in our size. After these are gone, the only way to make our cars perform properly will be to change tire sizes. (to 225/55/16 or 235/55/16). Larger wheel sizes are not prudent on this frameless, roofless, flexible flier.
(you will recall that the turbo trans am came with the same tires as the Ferrari Testarossa, Lotus Esprit Turbo SE, and many other exotic super cars. it was the finest tire of it's time. Today, the only tire in the correct size that approaches that level of performance or quality is the goodyear GSD3, and it is the lone holdout, soon to be extinct. Not long ago there were Pirelli, Michelin, Dunlop, Bridgestone and Continental tires from which to choose)
There may be a time when they start reproducing the goodyear gatorback tires. Probably when the bearded NCRS guys decide to press the button. but when that time comes, they may only be available in corvette size, which is 255 50 16. These will function just great on our cars. The PAS people specified the corvette size, for the tta. I don't remember why they didn't use them. probably gm did not want to have to put a different stop in the steering. Anyway, plenty of people use them. They perform better but may rub in front on maximum steering lock.
At any rate, when (if?) they are reproduced 5-10 years from now, the prices will be at least $400 per tire, and most likely $500. The cost of reproducing tires is very high.
For example: they just released some goodyear radial tires for the trans ams and corvettes of 1978 to 1982. The Goodyear Polysteel Radial for ta/s and vettes, and the goodyear GT Radial for 78 vette pace cars. These sell for $315-$420, depending on size and type. They will also be reproducing original RWL Eagle GT's in 215/70/15 and 255/60/15. These will cater to various A body cars (grand nationals, monte carlos, etc) and even some early 82-87 trans ams with 15" wheels. These 70's vintage radials are much simpler to make than gatorbacks... so if and when the gatorbacks are reproduced, they will have to be very expensive if they are faithfully duplicated. In fact, they used laser holographs and all kinds of fancy stuff when they made those tires. Reproduction tire molding plants probably don't have this equipment. When the original gatorbacks came out in 1983, they cost $225. (that is $450 in todays currency). And there is simply no way a reproduction tire molding outfit can do it as cheaply as Goodyear could. So figure more than $450. Plus, if it is another 10 years away, inflation will make it more like $600 per tire.
That is why the GSD3 is a bargain at $205. It could actually be a better tire. And you are getting it for less than 1983 prices. I am buying 5 of them and storing them until my new GSC's wear out.
