Have you ever looked at your car and wondered, How old are my tires? i’m guessing you probably haven’t. But maybe you should.
Now the obvious answer might be. Well i bought these tires about 2 or 3 years ago, so they must be 2 to 3 years old. Well chances are they are older than that. So how exactly do you tell when your tires were produced?
Lets take a look.
All tires in the US will have a US Department of Transportation (DOT) Tire identification number also referred to as a tires serial number.
All tire identification numbers looks like this and can be found on the side of a tire. If you only see this shorter, partial tire identification number, keep looking until you find the full tire identification number. You may have to look at the inside of your tire to find the 4 sections of text that is normally 11 digits, not counting the initial DOT lettering.
Breaking down this tire id number, DOT stands for Department of Transportation, PP refers to the plant code where the tire was made, XC refers to the tire size code, and AUZ refers to the tire manufacture code. Now all this information is nice, but what we really care about are the last 4 digits.
2616 is what is shown on this tire. The first 2 digits represent the Week of the year the tire was manufactured. so in this case, our tire was made in the 26th week of the year, which is around the end of June. And as you may have guessed, the last 2 digits represent the year the tire was made. So in our example tire here, this tire was produced in the 26th week of 2016.
A couple other examples, this tire was produced the 49th week of 2014 and this tire the 43rd week of 2010.
Now tires made prior to the year 2000 only contain a 3 digit date code… and those tire should all be gone by now…
So now that you can tell how old your tire is, you might be asking, can tires expire?
While there is no official expiration date for tires, the general consensus seems to be about 6 years.
And now before we go any further, just a warning about everything i am going to say next. These are simply my opinions about the life of a tire. I encourage you to do your own research and consider what makes you the most comfortable with your vehicles tires. Consult your specific automotive manufacture, tire manufacture, or professional service shop if you have question or concerns about your tires.
Now, in my opinion, just because a tire is 6 years or older does not mean it needs to be replaced immediately. If those 6 year old tires were stored in a climate controlled environment and not even sold for the first 4 years of there life, you could see how they would still be in good condition if they have the proper amount of tread left and do not show signs dry rot, cracking or any other visible wear.
I think this is the reason tires don’t have an exact expiration date. Storage, Climate, Tire pressure, vehicle load and driving style can all play in important roll in the life span of your tires.
I encourage you to inspect your tire periodically and run the right tires for your climate. If you live in an area that gets snow and ice I encourage you to research videos that show the difference between all season tires and winter tires on slippery terrain. Bottom line, tires are very important as they are greatly affect how your car accelerates, handles, and brakes. All of which should help you keep tire high on your automotive maintenance priority list.
