Al,
On May 5, 2004 Jay Laifman posted the following two quotes from Websites:
"The first two sets of numbers are for the manufacturer and the plant
> at which it was manufactured. The most important number is the last,
> which gives the week and year that the tire was manufactured. For
> example, a tire with a last number of 2103 would have been
> manufactured the 21st week of 2003, or June 2003. "
And
"To determine a tire's age, check the serial number. On tires made prior to
1999, the last three digits of the serial number will indicate the week and
year a tire was made.
For example, if the last three numbers are 228, it would mean the tire was
made during the 22nd week of 1998.
Starting this year, tire makers are required to use the last four digits to
indicate week and year. Nonnamaker said that was required when it was
discovered that some tire dealers were selling tires that were more than 10
years old. "
