I was surprised to learn that tire date code before CY2000 are unreliable because it does not reliably identify the year of manufacture. For example, the Code 319 indicates the 31st week of a year before CY2000 ending in a 9, so it could be 1979 or1989 or 1999........

The current DOT 4-digit code in use since CY2000 does indicate the year of a tire's manufacture. Code 2910 indicates the 29th week of CY 2010.

So the question is, "How old are the tires on your Model "A"?

Ford currently recommends replacing tires driven 12,000 to 15,000 miles annually that are 6 years old. However, some tire manufacturers suggest that tires are good for 10 years.
