I bought a 85 aspencade with 6000 miles and the tires had 400 miles on them cause I got the tire bill with the bike but they were 10 years old so I just bit the bullet and changed them also, better to be safe than sorry.
Well Dave, that's the ONLY stamp on the tire, period. The tire is required to have a date code...and looking at the tire closely it looks original (as was the front one)...so as far as I'm concerned, it's gotta be the date code. It makes sense that a 1998 model could have a tire made in 1997 and my research showed that some of the older date stamps contained more than the 3 digits representing the week/year, but that the last 3 were always the date. It seems that before 2000 the stamps were not quite as uniform as afterwards.That is not the date code. It should be a 3 digit # if before 2000 i.e. (327) if the 32nd week of 97.
