A tyre can be unsafe from age alone, even with plenty of tread left. Rubber hardens and cracks over time, reducing grip and raising the risk of failure. Most manufacturers recommend replacing tyres at 5 to 10 years old, and many advise against fitting any tyre that's already over six years old.
How to read the DOT date code
Every tyre has a DOT code on the sidewall ending in four digits. The first two are the week of manufacture; the last two are the year. So "2624" means the 26th week of 2024. If you only see three digits, the tyre is pre-2000 and should be replaced immediately.
Why age matters as much as tread
Heat, sunlight and oxygen slowly break down rubber compounds. An old tyre may look fine but have lost flexibility, leading to cracking and, in extreme cases, tread separation. Low-mileage cars, caravans, trailers and classic vehicles are most at risk because their tyres often age out long before they wear out.
Where to look beyond the date
- Spare wheels – often the oldest tyre on the car.
- Caravans and trailers – check these every season; many fail on age, not mileage.
- Part-worn tyres – can be deceptively old; see our guide to part-worn risks.
