A frequent question about tire maintenance concerns service life. How long will your tires last before you should replace them? The answer depends on different factors such as your driving style, the tread design of the tire, regional climate, road conditions, and how frequently the car is in use.
TIRE DATE CODES. How old are the tires on your vehicle? The date of manufacture is indicated by the last group of digits in the DOT manufacture code on the.
Tires are just about the most important part of your car. If they’re in bad shape, the car’s ability to accelerate, stop, and turn in all conditions is greatly compromised. Everybody knows to replace tires when the tread gets down to the wear bar, but what about when they get too old? The rubber in tires deteriorates over time due to UV and environmental exposure. The resulting “dry rot” leaves tire structure brittle and leads to sidewall damage and eventual failure.
This isn’t “Oh I’ll just fill it up and drive on it. As a precaution, the Department of Transportation recommends changing even new-looking tires once they hit 10 years old, and many manufacturers recommend swapping them out at six years old. Of course, this aging is highly dependent on where the tires live. Tires in hot dry climates have much shorter lives than those in moderate, moist climates.

Tires made before have a three-digit code that is trickier to decode. The first two digits still indicate the week, but the third digit tells you the year in the decade.
Everything from the type of tire and the tread can affect its ability to stay on the road, and its age plays a role as well. The rule of thumb is to replace tires when they are 6 years old, even if they appear to be in good condition. This is because the rubber can develop dry rot and other structural damage that you may not be able to see. You may be asking yourself how to tell when a tire was made, or how old are my tires?
How Old are your Tires? Your Safety may Depend on the Answer
In the past two decades we have developed a number of new designs that are the result of an extensive evaluation of a variety of variables. In addition, our tires require a higher degree of maintenance and repair, and our new tires must be removed and replaced on a regular basis to achieve the best performance. The performance and wear characteristics of most tires will only deteriorate with frequent use.
In extreme low speed maneuvers, the tires may require a less stiff tire compound and a higher performance tire sealant.
To find your tire’s date code, identify the code on the tire that begins with ‘DOT’. The ‘DOT’ should be followed by a series of four letters and/or numbers. You will.
If you’ve ever wondered how old your tires are, it’s an easy bit of information to find out. Tires actually have a “born-on” date, and it’s listed right on the tire itself. Almost everything you need to know about your tires is molded into the sidewall and coded according to federal requirements, including the specific week and year when a tire was made.
To read the date on a tire, look near the edge of the rim for a series of characters starting with the letters DOT. This code can tell you the manufacturer of the tire and the factory where it was made, as well as provide lot-specific information used for tracking in case of a recall. The last four digits of this code tell you when your tire was manufactured. The first two numbers indicate what week of the year it was made out of 52 weeks per year , and the second two numbers represent the year.
For example, would reveal that a tire was manufactured during the 52nd week of the year Prior to the year , DOT coding was slightly different. If you have a tire that doesn’t match the coding you see in our example, it was likely manufactured before and should be retired as a safety precaution. It’s always a good idea to have a tire professional inspect your tires when having them reinstalled on your vehicle after storage.
This will flex the tires and maintain oil dispersion within the rubber compounds.

Tires, like most other auto parts, are built to withstand a great deal of wear and tear. Unlike other car parts, however, tire manufacturers always give an estimate for about how long a tire should last. The estimates themselves can range greatly for each tire, but you’ll usually see a manufacturer listing of how many tens of thousands of miles you may expect out of that particular tire. When it comes to car part longevity, however, there are always circumstances when the auto part information given by a manufacturer may not apply.

Tires have very useful information molded onto their sidewall. It shows the brand and model name of the tire, its size, whether it is tubeless or tube type, the maximum load and the maximum inflation, safety warning s , and much more. The load range identifies the tire’s load and inflation limits. Load Index – The load index is a numerical code associated with the maximum load a tire can carry at the speed indicated by its speed symbol under specified service conditions. The load index should not be used independently to determine replacement tire acceptability for load capacity.
Max Load kg lbs and kPa 35 psi Max Pressure Cold — Passenger Example indicates maximum load and maximum cold inflation pressure of the tire. Sidewall markings are given in both metric and English units. Max Load Single kg lbs at kPa 80 psi Max Pressure Cold Max Load Dual kg lbs at kPa 80 psi Max Pressure Cold — Light Truck Example indicates the maximum load of the tire and corresponding maximum cold inflation pressure for that load when used in a single or dual configuration.

Luckily, you maintain control and safely maneuver to the side of the road. The tires are new, purchased a few months ago from a local tire shop. How could this happen to new tires? The fact is that all tires have an expiration date. Surprisingly, many consumers and sellers of tires do not know about tire expiration dates. An uninformed consumer thinks he or she purchased brand new tires when in reality those tires may have been sitting on the shelf for years.
Even though the tires were never used on a vehicle, they are still several years old. Every tire has a birth date—the day it was manufactured—and an expiration date that is six years from that manufacture date. Most automobile manufacturers warn drivers to replace vehicle tires after six years. To wait any longer than that is a gamble with tire integrity and is risky for drivers. So what can you, as a driver, do to protect yourself?

If not — you should. They may last another three years, but your tread has little to do with it. What is more essential is the age of the tire. Tires are made of rubber, obviously, and when rubber gets old, it starts to dry and crack often times from the inside out — this process is not always visible to the naked eye. Until recently, I had no idea that the age of the tire mattered. I thought it was all in the tread and visible cracking.
I also had no idea that tires have a manufacture date stamped on them. It turns out that tires have cryptic codes on them. Since , the week and year the tire was produced has been provided by the last four digits of the Tire Identification Number with the 2 digits being used to identify the week immediately preceding the 2 digits used to identify the year. While the entire Tire Identification Number is required to be branded onto one sidewall of every tire, current regulations also require that DOT and the first digits of the Tire Identification Number must also be branded onto the opposite sidewall.
The use of a partial Tire Identification Number on the one sidewall shown above reduces the risk of injury to the mold technician that would have to install the weekly date code on the top sidewall portion of a hot tire mold. The Tire Identification Number for tires produced prior to was based on the assumption that tires would not be in service for ten years.
