3. If your tyre shows signs of ageing
Tyres have no predictable life. It doesn’t matter when the tyres were made. Tyres age even when not used, or if only used occasionally.
There are many factors that will affect the life of a tyre, such as temperature, maintenance, conditions of storage, and use such as load, speed, pressure, driving style and damage.
Pay regular attention to your tyres
For these reasons, we recommend that all drivers pay regular attention to the external appearance of their tyres for clear signs of ageing or fatigue. This can include cracking of the rubber or deformation.
Excessive ageing of tyres may lead to loss of grip and weakening of the reinforcing structure. Michelin also recommends all tyres, including the spare, are inspected regularly by a tyre specialist. They can tell you whether your tyres should continue in service or whether your tyres need changing.
How old is too old? The five-year test
After five or more years in use, your tyres should be thoroughly inspected at least once per year. If the need arises, follow the recommendations of the vehicle manufacturer regarding replacing the original equipment tyres.
As a precaution, if the tyres have not been replaced 10 years from their date of manufacture, we recommend replacing them with new tyres, even if they appear to be in usable condition and have not worn down to the tread wear indicator
