i copied the whole this from a group i just made in facebook.
How old are ur tires?
my front ones were made in 33rd week of 2007 and rear ones were made in 52nd week of 2003.
this one is from another car. made in 22nd week of 2006
I was watching news after dinner and i happened to watch this short documentary about old tires being sold in the United States and becoming one of the causes of accidents.
This show showed how to find out when the tires were made and i'd like to share it for those who do no know how.
So here is how.
If u look at side wall of your tires there are bunch of numbers and codes.
skipping other codes and tire size spec., you'll see 3 or 4 digit numbers.
For instance, it could be 239, 136, 427, 5207, 3306, 1601 and etc.
These numbers might sound completely random but they have the manufacture year and which week of the year the tire was made in.
239 = 23th week of 1999
136 = 13th week of 1996
427 = 42nd week of 1997
5207 = 52nd week of 2007
3306 = 33rd week of 2006
1601 = 16th week o 2001
Do you get it?
first 2 digits show which week, last 1 or 2 digit digits show which year.
Why is this important to know?
Depending on environment the tires are in, they dry in several years.
Commonly 6-7 year old tires are ready to be disposed but some or many of dishonest tire manufacturers put new treads and sell them as new.
Customers who are aware of the secret hidden behind the code would buy 5, 10 year old or even older tires as they were to be new ones.
I was also one of them until today, the 9th of May in 2008.
What happens to those old tires with new treads?
The documentary also showed a couple of footages demonstrating how dangerous they could be.
As the test cars were cruising around 70, the tires' treads peeled off and it seemed like the tires exploded. Even though the driver with a helmet on knew that was gonna happen but he went, "S###!!!!"
So here is what I'd like u to do. Please Invite everyone you know to spread this information. This is for your own safety, and ultimately this could reduce the number of accidents.
