Question : THE DOT NYTM 2002
marking on my new tyres was seven years old.
Is it still safe to use ?
I do long journeys daily.
Answer : I hope you are reading the markings correctly as the DOT
markings read as follows:
The first two characters designate the tyre manufacturer and plant code.
This could be important if the tyre receives a safety recall.
The fifth, sixth, seventh and eighth (optional) characters identify the
brand as well as other characteristics important tot he manufacturer.
The final three numbers (four beginning in 2000) denote the date the tyre
was produced. The first two indicate the week, ad the last numbers specify
Assuming that your tyres were made in the 20th week of 2002, this could
mean that they have been sitting on a shelf for a long time and could have
deteriorated in performance.
If they have been properly stored, ie in a dark room and sealed from the
effects from ozone, they should be still quite good and safe for use,
although I would not use them for competition or very stressful driving.
