Because this process occurs naturally, it does not matter if a tire is being used, stored as a spare, or simply waiting on a store shelf for an unsuspecting consumer. A 2006 survey showed that only 4% of consumers are aware that tires become more dangerous as they age.In 1973, the average tread life of a passenger car tire was approximately 24,000 miles. If the tire has only 10 digits, the tire was manufactured before the year 2000. This six-year expiration date begins from the day the tire was manufactured at the plant—not the date it was sold to a consumer or the date that it was installed on a vehicle.Low mileage, older cars tend to be most at risk from premature ageing - as drivers assume the tyres are still in good condition if they have plenty of tread.Premature tyre ageing can affect safety and increase the risk of tyre failure.Once a tire begins to break down, it becomes more likely to fail in the form of a tread separation–often at highway speeds, when the failure is most likely to cause catastrophic injuries or death.For most tires, this expiration date should be six years from the date of manufacture.The first two digits of the code represent the week of production during the year (from 1 to 52) while the second two digits represent the year of manufacture.

…the tire that we use for sliding around on roads like that really works well from the beginning of the wear to where the tire’s almost destroyed...This is because tires are made mostly of rubber, and rubber degrades with age.Sunlight, heat, ice, and general wear and tear can accelerate the breakdown of a tire.For this reason, Kwik Fit urges drivers with tyres that are six years old or more to have them checked professionally to ensure they are still safe for use.Remember to check additional tyres such as spare wheels or those fitted to caravans and trailers as these tyres typically see less use and will be more susceptible to tyre ageing.
