How to find out the age of tyres?

Finding out the age of tyres

When it comes to the identity of tyres you will find that each is printed with a DOT code date on that informs you when it was manufactured.

This four digit age code is normally located on the outside of the tyre sidewall. Its first two digits represent the production week during the year. (These are coded from 1 to 52) whilst the second two represent the year it was manufactured.

In the case that your tyres are printed with a 3-digit number, this means they were made prior to 2000 and therefore need to be replaced ASAP. Although there is not a definitive tyre age limit, generally speaking if they are older than 5 years you should definitely be closely watching their condition and be considering replacement.

How is the ageing of tyres identified?

This is commonly shown by small cracks on the sidewall. Often this happens as UV light oxidises the rubber, in-turn causing this to then dry out. Although tyres contain a anti-oxidise to help slow this down, the substance is only released as the tyre is moving. Therefore in cases where a vehicle is stored away or is unused for awhile the tyres can age quicker and end up un roadworthy when wanting to return them to use.

Lower milage older vehicles tend to be at risk, a lot of drivers assume if the tread is good they are still in good condition. Premature tyre ageing can increase tyre failure, therefore we advise customers to be safe and have them professionally checked if they are six years or older to ensure they are still ok. Spare wheels, caravan, motorhome and trailer tyres should be checked regularly as these too can be susceptible to this happening.
