[TR] Tire age Query

[Francis P. Gowash]

Hi all,

Seems that I vaguely recall a thread on tire age as determined by a code on
the tire wall? Can't seem to find the key to this code. Can somebody remind
me? The only thing I've found resembling codes on my tires are 25266-2
followed by DESIGN 9526.

Following that, how does one determine replacement age of tires if car is
driven very little (<500 miles/year) and tires look very good externally?

Thanks much
