What you need to know about aging tires

Frequently asked question about the maintenance of tires affects the service life. How long tires will last before they will need to be replaced?

The answer depends on different factors such as driving style, tread pattern, local climate, road conditions and frequency of use of the vehicle.

One factor is you, the driver. As with the entire car, you play a leading role in the care and maintenance of your tires. The better you care for them, the longer they will last. In addition, you are responsible for making decisions about replacement of worn tires to new.

Use the guide below to extend the life of your tires. If after reading this article you still have questions, consult your local tyre dealer, he will gladly help.

Caring for the tires to extend their service

The company creates and designs Continental tires, designed for thousands of miles of excellent work. Get the most from your tires, taking care of them. This will help to avoid damage from improper use, which may shorten its lifetime.

The conditions under which your tires for daily use – air pressure, load, speed, damage to roads, etc. – are a major determinant of lifespan. Also these factors include regular changes of position of installation and proper storage. But since operating conditions vary considerably from car to car, driver to driver, it is impossible to create a universal prediction of the service life of the tire.


However, you can prevent the problem and increase the service life of your tires with proper maintenance. To avoid premature purchases of new tires, you should pay attention to the following points:

– Regularly check the tire pressure;

– Change the installation position of the tire between the front and rear axles and left and right side depending on the tread pattern;

– Maintain proper suspension geometry and alignment angles;

– Check the wear of the tread (1.6 mm is the minimum allowable rate, however, 3 mm for better grip and traction);

– Inspect the tires on the subject of visible wear and damage;

– Control the ride quality when driving

Check age of tyres

To determine the age of your tires is very simple: it is written on the sidewall! You can calculate the physical age of the tires on the marking, following the symbol “DOT”.

The last 4 numbers indicate the date of manufacture of the tyre to the week.

The first pair of digits indicates the week that is closest to the date of production of tires (ranging from “01” to “53”).

The last pair of digits is the year of issue.

For example, a tire with a DOT XXXXXXX2714 was manufactured in the 27th week of 2014.

What to remember about old tires

When viewed side remember the following:

– Tires manufactured before 2000, to indicate the date of issue is marked with three digits instead of four.

– In 1990-e years, Continental added a triangle (◄) after the character set. This was done in order to distinguish between tires produced in the 90-ies of the tire of past decades.

For example, a tire marked “DOT XXXXXXX274◄” was manufactured on the 27th week of 1994.

How old is the tire?

Continental does not have any technical data indicating that necessary exemptions from the use of tires that have reached a certain age. However, the tire applies the same principle as any other part of the car: age matters.

Together with other representatives of the automotive industry company Continental recommends to be withdrawn from service and replace with new all tyres (including spare), released over 10 years ago.

You need to follow this advice, even if:

– Tire condition seems good when viewed from the outside.

– The tread has worn away to a minimum.

In General, though, bus older than 10 years may look suitable for use, we recommend purchasing new tires for your vehicle. The driver should not rely on visual inspection the presence of cracking of the rubber, tread wear or other caused by age changes. The tire may look completely serviceable, but her age is a reason to replace it with a new one.

Some manufacturers may recommend a different age for replacement tires. Such instructions are based on understanding a specific method of use of the vehicle. Continental recommends that you pay attention to these instructions.

In any case, most often to change tires is tread wear or other reasons to reach the recommended replacement age. At the same time, the prescribed period of replacement tires does not absolve the driver from responsibility to replace worn tires as needed.
