Haggerty article said: "For example, a serial number ending in 4905 tells you the tires were
made during the 49th week of 2005. If there are no recognizable serial
numbers, you already have your answer – the tires were made prior to
2000 and need to be replaced."
That statement is misleading at best, and an outright lie at worst.
Tire made BEFORE 2000 also have date codes on them....it has been a standard for many years before the Gobment got involved. Date codes before 2000 simply do not include a specific serial number....just the date itself. The older coding did not allow for the decade of production because tire manufacturers dint expect tire to be in use that long, so they dint put what decade the tire was made on it, just the last number for the year/
First example(below) is coded for the 51st week of 2007.
Next example is the earlier coding, and shows a build date for the 40th week of the 8th year, but no decade....so it could be from '78, '88, '98.....who knows?
