I have never had Stones, but every other tire i have had has a stamped in number. 4 digit like 3106. Means tire was made the thirty first week of 06.

Just checked the spare 709 down in the garage. One one side only, you'll find DOT followed by a 4-digit alpha-numberic, right after that is imprinted 3 letters followed by 4 numbers. The four numbers are as stated above, the first 2 are the week and the last two are the year. Mine sez VBB2804, so it was made in the summer of 2004.

thanks I thought thats were it was, just want to confirm it.

Is there such a thing as having a new tire that is too, old (date code)? I know the 709s and 704s tires came on the first 1800s.

if it has been inside all of its storage life.

I RV a lot, and the general consensus on those forums is 5 years is the max safe life of a rubber tire, especially if its been exposed to the sun and other weather. They don't live that long on my bikes.
