The lifespan of a tire depends on many factors, including the ambient temperature and the conditions under which it is used or stored. In general, though, many experts agree that tires should be replaced when they are six to seven years old, even if they still have a lot of tread remaining.
The reason is that tires are kind of like rubber bands. If you’ve ever cleaned out a drawer and found an old rubber band at the bottom, it probably looked dried out, cracked. Over time, the same thing happens to rubber tires. Sometimes you can see the cracks, while at other times they develop on the inside of the tire. Aging can even cause the steel belts in the tread to separate from the rest of the tire. This process puts you at a much greater risk for a tire blowout.
You can check the age of a tire by locating the DOT number on the sidewall. The first two digits represent the week in which the tire was made, while the second two digits are the year. So a tire that reads 1714 was made in the 17th week of 2014. If you have any trouble decoding the age of a tire, ask your auto care technician for assistance.
