In this example, the manufacture date code is 1413 - where 14 denotes the week of manufacture and 13 represents the year, meaning this tyre was made in the 14th week of 2013.
If your tyres are printed with only a 3-digit number, it means your tyres were manufactured before 2000 and should be replaced asap.
Therefore, if the tyre is not used frequently or is stored away ineffectively, they will age more quickly rendering them unroadworthy when returned to use.
Therefore, because it is a safety issue, we recommend against using any tire more than six years old, and we cannot service them.
Granted, this type of failure can also happen to tires less than six years old when they heat up, but as the tire ages, the chances of having this problem go up dramatically.
From the year 2000 on, the date code has been 4 digits, the first two are the week of manufacture and the second two digits are the year of manufacture.
For instance 2407 would signify the 24th week of 2007.
Below are several examples showing how to check the date code and what happens when the tires get too old.
All of these tires just happened to be handy at the time of this post.
There has been a lot of media coverage in the last few years about the problems tires have when they get too old.
Most tire professionals have known about this for years and it's not just media panic, it is a serious issue.
This is brought about when UV light oxidises the rubber causing it to dry out.
While tyres contain anti-oxidising chemicals which significantly slow down the rate of ageing, this wax-like substance is only released when the tyre is in motion.
However the date code is (usually) only found on one side of the tire.
