How to find out whether your tyre has expired?
- Check for this sign: For example ( *4002* ) as shown in the picture.
- There is an asterisk at the beginning and at the end of this serial number.
- The first two numbers 40 will tell which week of the year has it been manufactured.
NB: One year has 52 weeks. The last two numbers represent the year of make.
Therefore, *4002* shows that the said tyre is manufactured in the 40th week of the year 2002.
Check all your tyres for safety purposes. Do not use expired tyres.
They are likely to burst whilst in use, because the rubber component may have hardened and cracked.
