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.

Old tyres can be a ticking time-bomb that could dangerously fail and lose air. Bridgestone explains how. Tyres are made of various types of textile, steel and rubber compounds that have properties that evolve over time. As the rubber in a tyre gets older and is exposed to the elements, the strength of the bond between the rubber and the steel belts is reduced.

When an old tyre is put under load, cracks in the rubber will begin to form. Eventually, the cracking can even cause the steel belts in the tread to separate from the rest of the tyre. Driving on such a tyre is a serious safety risk. Telling the age of a tyre that has not been retreaded is fairly straightforward.

Should auto tires have a sell-by date?

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. In the case of tires, the estimate of how long a tire can last is based primarily on the tread wear.

Vehicle owners are therefore encouraged to have their tires checked after five years of use, then annually thereafter. back to TOP. How do you determine the age.

The sidewall of your tires is filled with important information that tells you everything about your tire regarding the dimensions, construction, operating characteristics and manufacturer. The easiest way to understand tire markings is to take an example and break it down. The absence of a letter at the beginning of the size description indicates that the tire is Euro-Metric. The main difference is that Euro-Metric tires may have different load carrying capacities than their P-Metric counterparts.

The represents the approximate section width or width of the tire from sidewall to sidewall. The larger the number, the wider the tire. The 60 refers to the aspect ratio which is the nominal sidewall height reflected as a percentage of section width. The final component of the size designation is called the Service Description, which indicates the Load Index and the Speed Symbol for the tire. Load Index, or 97 in this example, is a two or three digit code that represents the maximum load that can be carried at the speed indicated by the speed symbol.

In order to determine the actual maximum load for the tire, you must consult the Load Index Chart below. The Speed Symbol, or V in this example, indicates the maximum speed for the tire, but it is more like a performance rating that reflects the handling characteristics after it is installed on the vehicle.

Automobile tires are described by an alphanumeric tire code in American English and Canadian English or tyre code in British English , Australian English and others , which is generally molded or moulded into the sidewall of the tire. This code specifies the dimensions of the tire, and some of its key limitations, such as load-bearing ability, and maximum speed.

Sometimes the inner sidewall contains information not included on the outer sidewall, and vice versa. The code has grown in complexity over the years, as is evident from the mix of SI and imperial units, and ad-hoc extensions to lettering and numbering schemes. Most tires sizes are given using the ISO Metric sizing system. The DOT Code is an alphanumeric character sequence molded into the sidewall of the tire and allows the identification of the tire and its age.

The code is mandated by the U. Department of Transportation [1] but is used worldwide. The British Rubber Manufacturers Association BRMA recommended practice, issued June , states, “BRMA members strongly recommend that unused tyres should not be put into service if they are over six years old and that all tyres should be replaced ten years from the date of their manufacture.

All tires sold for road use in Europe after July must carry an E-mark. An upper case “E” indicates that the tire is certified to comply with the dimensional, performance and marking requirements of ECE regulation The number in the circle or rectangle denotes the country code of the government that granted the type approval. The last number outside the circle or rectangle is the number of the type approval certificate issued for that particular tire size and type. The ISO Metric tire code consists of a string of letters and numbers, as follows:.

Reading a Tire Sidewall

The structural integrity of a tire can degrade over an extended period of time. When that occurs, tires are more prone to catastrophic failure, which could, at best, cause an inconvenience, or, at worst, lead to a crash. The degradation of a tire occurs over time, mostly the result of a chemical reaction within the rubber components. That aging process can be accelerated by heat and sunlight. Does climate have an effect on the aging of tires?

NHTSA research suggests that tires age faster in warmer climates.
