The tire industry has long acknowledged the role of the consumer in the regular care and maintenance of their tires. It is down to owners to decide when their tires need to be replaced and they need to base this decision on factors like usage conditions, maintenance intervals, storage conditions, visual inspections, and the dynamic behavior of the tire. Consumers should consult a tire specialist if they have any questions regarding the service life of their tires. The following information and recommendations have been compiled to help you determine the maximum possible service life for your tires.
Tires are developed and manufactured to offer both high mileage and maximum utility. It is also necessary to maintain them properly in order to prevent tire damage and improper use, which could make the tires unusable.
The possible service life of a tire specifically depends on the cumultative effect of storage, operating, and service demans that the tire is exposed to over its lifetime (loading, speed, inflation pressure, cutting damage, etc.). Because these usage conditions can vary greatly, it is not possible to predict the possible service life of any one tire based on its chronological age alone.
The consumer plays an important role in caring for and maintaining the tire
There are many reasons why a tire may need to be taken out of service, e.g. when the minimum tread depth is reached or it has been damaged or abused (puncutres, cuts, impacts, cracks, bulges, underinflation, overload, etc.). For this reason, tires must be regulary inspected at least once a month. These routine inspections become even more important the longer the tire is in use. If damage is detected or even suspected, Continental recommends that a tire specialist be consuited to determine whether the tire is fit for continued use. Routine inspections must also be carried out even if the vehicle is equipped with a tire pressure moitoring system (TPMS).
Consumers are strongly encouraged not only to inspect their rires visually, but also to note all changes in dynamic behavior, such as increased air loss, noise, or vibration. This could be a sign that the properties are no longer as intended ans that it should therefore be taken out if service immediatly to prevent it from failing completely. If motorcyclists expericence a heavy blow or impact to tje tire while in use, they shoukd ensure that the tire is examined immediatly by a tire specialist.
The way in which tires are prepared for storage, stored, and fitted to the vehicle are also important factors in the possible service life of the tire. Further information about this is available in other Continental publications on request and on the Internet.
Recommended service life of tires
Continental is unaware if any documents or data that are able to support a specific age at which a tire should be removed from service. Nevertheless, together with other tire and vehicle manufacturersm Continental recommends that all tires more than ten (10) years old be replaced with newer ones.
This also applies to tires that still appear to be usable from their external appearance and whose tread depth is still within the legally prescribed limits. Vehicle manufacturers may recommend a different chronological age at which a tire should be replaced based in their knowledge of the specific application; Continental advises that any such recommendations are complied with. Consumers should note that most tires need to be replaced before they reach the end of their recommended service life due to wear or other reasons. A recommended service life does not in any way relieve the consumer from their obligation to replace tires when necessary.
Determining the production date of tires with the date stamp
The production date of any tire can be found on the sidewall after the "DOT" logotype. In the case of tires produced after 1999, the last four figures indicate the production date, with the first two of these representing the production week (and so ranging from "01" to "53") and the last two the production year (e.g. a tire with the marking "DOT XXXXXX2713" was manufactured in the 27th week of 2013).
