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.
