Tyres are constructed using various types of material and components where the properties evolve over time.
This evolution depends upon the storage conditions (temperature, humidity, position, etc.) and conditions of use (load, speed, inflation pressure, condition of wheels, etc.) to which the tyre is subjected.
Since the aging factors vary and are difficult to measure, that is why in addition to regular inspections by the user, Michelin recommends that tyres should be inspected regularly by a qualified tyre specialist who will assess the tyre’s suitability for continued service.
This inspection must take place at least once a year. If the tyre has been in use, it must be inspected at the earliest upon 5 years in circulation. If the tyre has not been in use, it must be checked at the earliest upon 8 years.
At the end of one of these periods, in addition to the normal visual aspect and pressure check, tyres should be inspected annually by a tyre specialist.
It is recommended that tyres 10 years or older are not used on steering axles of trucks and buses.
It is recommended that they be used on Trailer (T) axles.
Failure to follow these recommendations may lead to a reduction in the performance your vehicle and cause it to respond abnormally and/or a tyre could pose a safety risk to the user and others. Michelin shall not be responsible under any circumstances for damage that occurs as a result of and/or during use that does not comply with its guidelines.
