Keeping tyres for more than 10 years: possible or dangerous?
Are your tyres over 10 years old, and are you wondering whether they are still usable? Although no law prohibits it, their natural ageing, even with moderate use, can make them dangerous. Here is what you need to know to assess their condition and decide whether it is time to replace them.
Understanding tyre age through the DOT marking
Every tyre has a manufacturing date marked on its sidewall, known as the DOT (Department of Transportation) code. This indicates the year and week of manufacture. For example, a tyre marked "2314" was made in the 23rd week of 2014.
Although this is not an expiry date, the recommended limit is 10 years after manufacture, even for tyres that have seen little use or have been stored well. Beyond this point, their performance declines and they become potentially dangerous.
Tyre life and condition
The life of a tyre depends on many factors:
- Original quality: Premium tyres (Michelin, Bridgestone, Continental, Pirelli, Goodyear, Hankook and Dunlop) age better thanks to better-performing materials. These tyres are designed to offer safety, grip and a long life, making them ideal for demanding drivers. Their advanced compounds and innovative technologies provide greater durability. These tyres retain their performance for longer, even after several years of use.
- Maintenance: Correct pressure, regular balancing and suitable storage conditions extend their life.
- Use: Smooth driving and moderate mileage reduce wear.
Even if your tyres appear to be in good condition, it is important to check for signs of ageing:
- Cracks in the sidewalls or tread
- Crumbling or hardened rubber
- A bulge appearing
These signs indicate an immediate danger, such as a possible blowout.
Driving on tyres over 10 years old: what are the risks?
Driving on tyres that are too old can lead to:
- A loss of traction, particularly in rain or snow.
- An increase in braking distance, even at low speeds.
- A sudden blowout, especially at high speed, endangering the driver and other road users.
Winter tyres over 10 years old are even riskier because their rubber hardens further at low temperatures, reducing grip.
What does the law say?
No regulation specifically prohibits using tyres over 10 years old. During the roadworthiness inspection, the manufacturing date (DOT) is not checked. However, the general condition of the tyres is checked, including:
- Tread depth (legal minimum of 1.6 mm).
- The absence of cracks, bulges or other visible damage.
Older tyres can therefore fail the inspection if their condition is considered insufficient for safe driving.
When should you replace your tyres?
Here are some good practices to avoid risks:
1. Check your tyres regularly: A visual inspection every 2 to 3 months and before long journeys is essential.
2. Plan their replacement: Do not keep them beyond 10 years, even if they still look good. Ideally, start monitoring them closely after 5-6 years.
3. Do not overlook the spare tyre: It ages too and must be inspected regularly.
Conclusion: put safety first
Driving on tyres over 10 years old is not prohibited, but it is a risk not worth taking. Signs of ageing, even subtle ones, can put your life and the lives of others at risk.
Make a habit of checking your tyres regularly and replace them as soon as they reach their age limit or show signs of wear. By choosing quality tyres, you invest in your safety and peace of mind on the road.
If in doubt, consult a professional for a full tyre inspection.
