GoodyT said:There is no MFG date on my tires so they seem to be pre 1993 as the consensus is that's when tire manufacturers started to stamp dates on tires.
That's not true....tire dating has been done for many years....long before '93. The date stamps are normally only on the back side of the tire, so if you did not look there, you wouldn't see it. I have an article somewhere describing date de-coding on tires....I'll see if I can dig it up this evening when I get home. I
think there was also a thread here before that had the same info. I can check that now....
I did find this in an old thread...it gives basically the same info....

was thinking last night when I posted but I had to go back and edit to
correct what I said. It was late and I was sneaking in some reading
while doing my month end closing for work which I am late on! (Again)!
Any way
the build date always follows the DOT number and can be either a
3 digit or 4 digit number. Its usually only on one side of the tire and
can be inside or outside depending on Manufacturer and mounting. If its
only a 3 digit number the first 2 will be the week of the year and the
last digit will be the year. 3 digits are 90's tire. 4 digits are
usually the 2000 and newer. Hope this clears up my mistake!

Also, the Federal Guvment started requiring a uniform dating on ALL
tires starting in '71. Up until then, each manufacturer had their own
way of dating tires.
The original Firestones on my '74 are dated.....can't remember the dates, but I do know I have checked them.
