here's what "The Pocket Ref"* has to say..."the code is XXYY MMM999. The
XX is the manufacturer, the YY is the tire size. MMM is the optional
tire code and the 999 is the date of manufacture. For more details
request a copy of "Part 574 - Tire Code" from the U.S. Departmant of Transportation."

* an absolutely indispensible book from Sequoia Press. Don't leave home
without it!
