Tire Date Code: What You Need To Know

Bridgestone Tire Clinic | Tire Talk

So you’ve already got a grasp of the tyre basics, such as tire pressure, tread depth and even tyre tipes! However, did you know that you can easily tell your tires’ age?

Similar to other tire wear and performance factors, age can and will affect the performance of tires. This therefore will impact overall vehicle safety and capability, thus it’s something you should pay attention to.

Not sure how old your current tires are? No worries, we’ll show you how to easily find out!

Locating the date code

For tyres manufactured after the year 2000, you’ll find each tire’s ‘birth date’ stamped on its outer sidewall. This number follows a standard, straightforward format of the week and year represented as a 4-digit number (WWYY).

To find the date code, simply scan the tyre sidewall in a clockwise direction, and locate a series of letters and numbers within a raised rectangular box. The 4-digit number within the box are the numbers you need – the date code!


Deciphering the date code

The date code follows the ‘WWYY’ format, with the first two numbers representing the week of manufacture, and the last two numbers indicating the year.

On this ALENZA 001, the date code is “0619.” Breaking this down, this indicates that the tire was manufactured in the 6th week of the year, in the year 2019. As such, we can deduce that the tire was manufactured between 4th February 2019 and 10th February 2019.


Does the tire age matter?

Tires are constructed of many organic, natural materials. Like other organic materials, the rubber compounds in a tyre will degrade with time.

When new tires are stored improperly and exposed to the elements, however, degradation will be accelerated, resulting in dry rotting and cracking, and a shorter overall tyre lifespan.

At Bridgestone authorised tire dealers and Bridgestone B-Select concept stores, you can rest assured that every Bridgestone tire you purchase has been stored with the utmost care, ensuring that you can enjoy your Bridgestone tire for the longest possible time.

From the moment your Bridgestone tires are produced at our factory, all the way to the point where they reach the authorised Bridgestone tire dealer’s shop, our proper logistics procedures ensure that tires are always stored and stacked to avoid damage. This means that your tires are stacked properly, stored in a dry location, and kept away from sunlight and heat.
