    and, what's the outside limit date code you'd accept on a tire for a high performance car, like a Ferrari?
    e.g. 6 months, a year? longer?? I know these tires can sit, getting older, in a warehouse. thanx steve

    I thought it was generally six years. However, see here.

    See here for what Michelin says.

    A lot of our sizes are getting hard to find, and maybe "once a year" type production.....so consider that.
    That might see you looking at tires more than 12 months from manufacture.

    As far use on the ground, most (ALL?) say that at five years no matter the apparent condition the rubber has lost critical chemicals related to traction and braking performance and should be changed.

    I fitted some "new appearing" warehouse finds over the Goodyear advice, and they fragged out in less than six months, in a dangerous way.
    So "they" are right, in this case!!

    I think you're being reasonable. Close to 2 years seems a tad too long to me. I start to get itchy to replace them when it gets to be 4 or 5 years after the date stamp, regardless of mileage and tread wear. So, close to 2 years is almost half that time frame. Most of the tires I've bought from Tire Rack have a date code that's typically 6 - 9 months before I bought them...T

    What car are they going on and how many miles a year will you be doing in it?

    ...or rather will you wear the tread out before the tyres are 6 or 7 years old?

    they're going on a Daytona, and I doubt i'd wear the tread out (who does, really?), but i'm worried about tire compound deterioration over time. s

    Have you actually bought them yet? If not shop around and see if you can get some newer ones, but the article here implies that the ageing only really starts when the tyres are mounted on a rim.

    It also depends on the price you paid or will be paying. Use the age as a bargaining point to get a discount.

    i wouldn't think the mounting status would matter, but you're right, it's written vaguely. I've purchased the tire already, so I know there' about 18 months already on it. Coker was willing to check the date, but I bought it elsewhere. Did think about asking for a prorata refund, and if I don't return it, that's my strategy. thanx s

    I've kept them on the car for 8 years in the past.
    Be sure to ask the retailer what the date codes are BEFORE ordering. I bought a set of tires for my (ex) 250 GTE a few years back from a well known tire retailer. When they arrived they were already 2 years old.

    I did ask, and was reassured that they would be fresh, but were being drop shipped so they couldn't promise me anything. Nonetheless, that ain't my problem and, on eBay, your feedback score is a powerful tool. Offered a fair prorata deal and now waiting to hear. thanx. s
