You just need to know how to get them. You might have difficulties while reading codes on old tires. Keep reading to know how old your tire is.
Ways to Get Your Tires DOT NumberLook at all the sides of the tires. There are a bunch of numbers and letters. It might seem like a jumble. But this is helpful information about the tire. Find the number that starts with DOT and followed by ten to twelve series. This code will reveal a lot of things about your tires. You will know the tire size, year, and place of the manufacturing with the unique code of the manufacturer. You can also rent a wheel payments to know more about tires. Once you rent a tire payments, you will not have to be bothered about the manufacturing year. They will take care of this. You just need to look for a rent a wheel return policy to make it more beneficial for you.
Remember that the last four digits of the code are the date the tire was manufactured. You can check the first two digits of the DOT code to know the week of the manufacturing. The last two digits will reveal the manufacturing year. For instance, when it was written in 0203, the manufacturing year was 2003.
But it is a bit tricky to know the manufacturing year of tires manufactured before 2000.
You need to check the last three digits of the DOT code. Check the first two digits to know the week. For instance, when the last three digits read 022, you should understand that the tire was manufactured in the 2nd week of that year. You might be thinking about how to know the year. The year is the 2nd year of that decade. It is easy to get confused to know the decade. It might be harder to know the exact decade. There might be some other indications to know the year.

Are you concerned about the age of your tires?
This quick guide will help you find the manufacture date of your tire and understand how Tires Easy handles tire age based on the DOT Code. Keeping a record of your tires and understanding their age will help you save money on repairs and take proper care of your vehicle.
To find your tires’ age, you need to locate the DOT Date Code on the tire. This symbol indicates the tire manufacturer’s compliance with the U..jpg)
S. Department of Transportation (DOT) National Highway Traffic Safety Administration (NHTSA) safety standards. It tells you who manufactured the tire, where it was made, and other tracking information. Plus, it indicates that the tire has passed the Department of Transportation’s testing and NHTSA manufacturer requirements.
The raised numbers of the DOT Code are placed together and often enclosed in a raised oval. The first two numbers are the week the tire was manufactured. In the example below, 35 stands for “week 35.” The second two numbers are the year the tire was manufactured. In the image below, we see the 07, indicating the tire was build in 2007. This particular tire was made in the 35th week of 2007.
On tires that were manufactured in 2000 and after, the last four digits indicate the week and year the tire was produced. The first two digits identify the week and the second two identify the year.
It’s not always easy to find the tire DOT code.
There aren’t regulations on where the manufacturer has to place the information, so you may need to look at multiple sides of your tires before you can find the numbers. However, the identification information is usually on the inner sidewall of tires.
At Tires Easy, we believe that the tire warranty should begin from the date of purchase, not the DOT Code. If you purchase new tires today, and the DOT Code was a year ago, your warranty will still begin on the purchase date, not the manufacture date of the tire.
If for any reason you are uncomfortable with the age of your tires after looking at the DOT Date code, please call us and we can quickly provide you with a return under our 45 day return policy.
Just because you buy “new” tires doesn’t mean they were actually made recently. It can take a while for tires to reach tire retailers after being shipped from the manufacturer.
Checking your tires’ DOT Date Code will tell you when they were made and how long they may have been stored. It is important to know that tires are often for months or years at a time, so your tire’s DOT code might not be in the same year you bought the tires, and that’s not a concern.
At Tires Easy, we take tire protection VERY seriously. Once the tires reach us, they are moved into Tires Easy’s industrial tire warehouses to ensure proper storage and prevent exposure to seasonal weather conditions. Our storage locations are cool, climate-controlled, and dry, preventing any premature aging or damage. Tire aging can be rapidly accelerated by poor storage conditions, so you should be sure the tires you purchase have been properly stored.
A general consensus from various tire industry associations around the world is that tires have a useful service life of six to ten years. As technology changes, there are more materials, and combinations of comounds, to extend tire life and extend wear.
At Tires Easy, we like to err on the side of caution and only sell tires that are seven years old and under. If you consider that the average driver travels 15,000 miles per year, most tires need to be replaced in 4 years. If your tires were a few years old when purchasing, you would still be well within the accepted tire age range. This is especially true if the tires receive the proper amount of care and maintenance over the course of their lifetime.
Legally, you must replace your tires when the tread depth falls below 1.6 mm. Additionally, it’s recommended that you change summer tires at 3 mm and winter tires at 4 mm tread depth. This keeps your tires at optimal levels of safety.
When your tires reach seven years of age, we recommend that you consider replacing them. Even if the tires look new, it is best to have them inspected by a professional tire installer, so they can properly advise on the safety of the tires moving forward. Spare tires should be checked and replaced as well.
No matter how old the tires are when you buy them, the most important aspect of tire safety is regular maintenance and inspection. According to the The Rubber Manufacturer’s Association of America and the Tire & Rubber Association of Canada.
“Since service and storage conditions vary widely, accurately predicting the service life of any specific tire based on calendar age is not possible.”
For this reason, there is no specific limitation on the age of the tire when it is sold based on its DOT Code.
1. In terms of the DOT Date Code, some might assume that the number states when the tire was approved. On the contrary, the DOT symbol by itself simply indicates that the tire is approved by the Department of Transportation to be legally used on the road. The Date Code is when the tire was manufactured (not when it was approved).
2. You might also have heard that you should only buy tires that have a DOT code within the current year.
As we mentioned earlier, this is often not the case with many tires simply because it takes time for the tire to reach the United States from the manufacturer. As long as the tires have been stored properly, they will be in excellent condition, even if the DOT Date code is a couple of years old.
When stored properly and protected from the elements, tires age quite slowly. The Rubber Manufacturers Association has said there’s no way to put a date on when tires actually “expire.” There are too many factors that impact the true age of a tire.
To help prolong the life of a tire, tire retailers will:
While these are the main contributors to excessive tire aging, it would still take years of exposure in the hottest, wettest, and driest climates for the first signs of tire aging to appear.
Tires are durable, and if they’re showing signs of damage within the first few years, it’s a sign of poor quality. Whitening of the rubber and shallow hairline cracks in the upper or lower sidewall may be an indication of UV and heat damage, but these symptoms aren’t issues you commonly see in new tires.
Sidewall cracking due to UV rays
Yes, the rubber gets hard over time as the tire loses its elasticity. This happens regardless of how much you use your tires over the course of the years.
Every tire has a birthday, and many tires will not be sold 7 years later. However, since some tires don’t technically become unsafe until a decade after they’re produced, the best advice is to have your tire checked by a professional to make sure they are safe for continued driving.

For tires manufactured in 2000
Date of manufacture is the last four digits of the DOT code.
The first two digits are the week of manufacture and the last two digits are the year. For example, if the last four digits of the DOT code are 0203, this means that the car tire was manufactured during the second week of 2003. Pretty simple, right? However, if your tires were made before 2000, things get a little more complicated.
The date of issue is the last three digits of the code. The first two digits refer to the week in that year. For example, if the last 3 digits are 022, this means that the car tire was produced in the second week of the year, and the year is the second year of the decade. Here's where it gets confusing - there's no universal identifier that specifies which decade, so in this example, the tire could have been made in 1982 or 1992. Some tires have a small triangle following the DOT code to indicate 1990s.
If you look at the sidewall of the tires and see a DOT number that seems incomplete, it's because current DOT regulations require the entire number to be on only one sidewall, while only the first few digits are on the opposite sidewall.
To see the entire DOT number, just look at the other side wall.
The tire release date is always stamped on the following tire manufacturers:
Amtel, Barum, Bridgestone, Continental, Cooper, Cordiant, Dayton, Debica, Goodyear, Dunlop, Falken, Firestone, Fulda, General, Gislaved, Hankook, Kama, Kelly, Kleber, Kormoran, Kumho, Marshal, Matador, Maxxis, Michelin, Nitto, Nokian, Pirelli, Sava, Semperit, Tigar, Triangle, Toyo, Uniroyal, Yokohama.
However, don't pay too much attention to the age of the tires when buying, especially if they are less than two years old. Practice shows that such automotive rubber is no worse than the one that was made just a month ago. And the performance and durability of tires primarily depends on their original quality. Choose quality tires.

No matter how ridiculous it may sound, but you need to choose tires for a car that are "fresh".
This applies to both the purchase of new and the purchase of used wheels. After all, the safety and comfort of a trip largely depends on the physical condition of the tires. And they have their own shelf life and operation.
Subject to certain rules of packaging, transportation and storage of tires, the manufacturer guarantees the safety of the operational properties of tires for 5 years from the date of production. You can use tires after this period, but with a mandatory check of their condition at the beginning of each season.
Non-observance of storage conditions leads to loss of rubber elasticity. Rubber becomes harder, microcracks appear on its surface. Signs of aging seriously impair tire performance. The possibility of their further use is determined by the buyer himself, based on the technical condition of the tires.
To find out the date of manufacture of the tire, just look at the side surface of the tire. Here, along with other alphanumeric information, there is a four-digit number enclosed in an oval.
It is located at the end of the DOT code.
Regardless of the country of manufacture and the geography of tire sales, the numerical marking in the oval indicates the week number and year of manufacture of the tire. The first two digits are the production week number. The last two are the year of release. In our example, the numbers "3706" indicate that the tire was manufactured on the 37th week of 2006, that is, in the first week of October 2006.
A three-digit coding indicates that you have a tire in front of you that was created before 2000. For example, the code "127" indicates that the tire was made in the 12th week of the 7th year. To accurately identify the decade, pay attention to what comes after the number 7. The presence of a space ("127_") or another sign ("127▵") indicates 1997 issue. The absence of a space or signs - for 1987 production.
This complexity in the designation is due to the fact that in the 20th century, tire manufacturers did not expect that their products would be used for more than 10 years.
They switched to a more convenient 4-digit marking after 2000.
Japanese tires enjoy well-deserved popularity in the world. One of the brands, Bridgestone, has been producing a wide range of tires for cars, trucks and sports cars for more than 80 years. Each type of tire bears a standard marking of the rubber production date. The year of manufacture on Japanese tires is indicated on the sidewall, after the DOT marking. Look for the last 4 digits enclosed in an oval. The first two of them are the week number of the tires, the last two are the year of manufacture.
Without exception, all leading manufacturers recommend changing tires if they are 10 years old from the date of manufacture. Rubber older than 8 years is considered potentially dangerous to use.
Many offline and online shops offer to buy tires no older than 3-5 years.
