Hi Signman,
The following is from Wikipedia

DOT Code
This article or section deals primarily with the United States and does not represent a worldwide view of the subject.
Please improve this article or discuss the issue on the talk page.

The DOT Code is an alphanumeric character sequence molded into the sidewall of the tire for purposes of tire identification. The DOT Code is mandated by the US Department of Transportation. The DOT Code is useful in identifying tires in a product recall.

The DOT Code begins with the letters "DOT" followed by a two numbers or letters plant code that identifies where it was manufactured. The last four numbers represent the week and year the tire was built. A three-digit code was used for tires manufactured before the year 2000. For example, 178 means it was manufactured in the 17th week of 8th year of the decade. In this case it means 1988. For tires manufactured in the 1990s, the same code holds true, but there is a little triangle (?) after the DOT code. Thus, a tire manufactured in the 17th week of 1998 would have the code 178?. After 2000, the code was switched to a 4-digit code. Same rules apply, so for example, 3003 means the tire was manufactured in the 30th week of 2003.

Other numbers are marketing codes used at the manufacturer's discretion.

Hope this answers your question.
Cheers,
Wayne.
