The TyreScan app reads your DOT code and tyre size automatically using your camera. No typing — just point and scan.
Every tyre sold in the UK has a DOT code moulded into the sidewall. Look for the letters DOT followed by a series of letters and numbers. The last four digits are the ones you need — they tell you exactly when the tyre was made.
The DOT code above shows a tyre made in the 23rd week of 2019. Only the last four digits matter for age checking — ignore everything before them.
Your tyre size is printed on the sidewall in a standard format used worldwide. Here's what each number means:
Tyre rubber degrades over time even if the tread looks fine. Heat, UV light, and oxidation cause the rubber to harden and crack from the inside — which you can't see from the surface.
Most tyre manufacturers and the RAC recommend:
Your tyres are within their expected lifespan. Continue with regular tread depth checks and visual inspections for cracking or bulges.
Tyres in this range should be inspected by a qualified tyre fitter annually. Look out for sidewall cracking, which is a sign of rubber degradation. Consider replacing sooner if the vehicle is used heavily.
Most manufacturers recommend replacing tyres at this age regardless of tread depth. The structural integrity of the tyre may be compromised, increasing the risk of a blowout especially at motorway speeds.
Note: Some manufacturers set their limit at 6 years, others at 10. When in doubt, ask a tyre fitter to inspect them.
