TIRE IDENTIFICATION & RECORD KEEPING
The National Highway Traffic Safety Administration (NHTSA) ?Tire Identification and Recordkeeping Regulation? has been revised. Effective July 2, 2000, all tires used domestically must adopt the new 4-digit date code. January 1, 2000, was the effective date for tires used in Europe.

Previously, the Regulation required a 3-digit date code; the first two numbers specified the week of production, while the third number indicated the year. With the old system, the numbers repeated every ten years. This caused confusion at times, particularly with some tire designs that may not have changed during a 10 year span.

Under the new Regulation, the first two symbols must identify the week of the year by using ?01? for the first full calendar week in each year, ?02? for the second full calendar week and so on. The final week of each year may include not more than 6 days of the following year. The last two symbols must identify the year. For example, 0101 means the first full calendar week of 2001, or the week of January 7 through 13, 2001

Good information Frank, this is something all owners should check when buying new tires it's common to be sold one that has been sitting around a few years and reducing the life of the tire.
