Tires are manufactured using rubber, carbon black and a combination of some chemicals that holds all the components intact; the tires are mostly durable for a certain period after the date of manufacture. Tires have shelf life and if they are kept longer than this period of time, it makes them unfit for road use or sales; the reason is because their rubber would lose quality over time.

On December 27, , the federal Office of Price Administration initiates its first rationing program in support of the American effort in World War II : It mandates that from that day on, no driver will be permitted to own more than five automobile tires. The first limited the purchase of certain commodities tires, cars, metal typewriters, bicycles, stoves and rubber shoes to people who had demonstrated an especial need for them.
The second limited the quantity of things—like butter, coffee, sugar, cooking fat, gasoline and non-rubber shoes—which every citizen was allowed to buy. As a result, of course, the black market flourished—studies estimated that 25 percent of all purchases during the war were illegal. Japanese occupations in the Far East had made it impossible to get rubber from plantations in the Dutch East Indies, and what little rubber was available went straight to airplane and munitions factories.

The manufacture date is located on the sidewall of the tyre, displayed as a four-digit number; the first two are for the week and the last two for the year.
When buying new cars, you also get a new set of tires. But when replacing tires after some years, you need to know the tire information on the sidewall.

Even if a car is stored inside and the tires pass a visual inspection no cracks, dry-rot or other visible deterioration we typically suggest replacement after 10 years if you plan on driving it.
So, what happens if you drive on a tire that is more than 10 years old? You could get lucky and the tire could last until the tread is worn down, or the tire could separate without warning.

The estimates themselves can range greatly for each tire, but you’ll usually see a manufacturer listing of how many tens of thousands of miles you may expect out of that particular tire.
When it comes to car part longevity, however, there are always circumstances when the auto part information given by a manufacturer may not apply. In the case of tires, the estimate of how long a tire can last is based primarily on the tread wear. But some safety advocates want to add an expiration date of six years onto each tire, regardless of how much tread is left on them. The reason for setting up this six-year standard is that some research has shown that after that amount of time passes, tire failures dramatically increase.
Although there isn’t a set expiration date as of yet, companies like Ford Motor Company already encourages its customers to scrap their tires if they’re more than six years old [source: Holguin ]. But how can you determine the age of a tire? You can tell how old a tire is by looking on the tire’s sidewall. There are lots of markings ranging from the type of tire, a speed rating that corresponds to a maximum safe speed your tire can sustain, the size of the tire and also when the tire was made; however, if you look after the Department of Transportation DOT letters, you’ll see another list of numbers.

Tyres are made of various types of textile, steel and rubber compounds that have properties that evolve over time.
