Checking the date on your tires is a crucial safety measure that can help you avoid accidents and extend the lifespan of your tires. The date code, also known as the DOT code, is a series of numbers and letters molded into the sidewall of every tire. The last four digits of the DOT code represent the date the tire was manufactured, with the first two digits indicating the week of the year and the last two digits indicating the year. For example, a DOT code ending in “1521” means that the tire was manufactured in the 15th week of 2021.
It is recommended to replace your tires every six to ten years, regardless of how much tread they have remaining. This is because the rubber in tires degrades over time, even if they are not being used. Driving on old tires can be dangerous, as they are more likely to experience blowouts and other failures.
