Useful Tips
Did you know you can work out the age of your tyres, right down to the week and year of manufacture? This is useful to know when checking unknown tyres on a vehicle! A tyre will naturally degrade (the materials within slowly 'dry' out) over time regardless of its use, and as tyres degrade they are more prone to failure.
The marking you need is found on the sidewall, and denoted by either 3 numbers if manufactured before 2000, or four numbers after 2000.
For example:
Where 34 denotes the week of manufacture and 9 represents 1999. This tyre was manufactured in the 34th week of 1999.
Where 16 denotes the week of manufacture and 04 represents 2004, meaning this tyre was made in the 16th week of 2004.
