Little Help with Tire Dot Code
I decided to check some of my tires for dates.
look for the DOT then find the last four numbers and that's your week and year they were made.
also 4 digits is after 2000 and 3 digits are before. If it has a triangle beside it, it's the 90's if it doesn't it's the 80's.
Here's my code on a set of Michelin's
DOT 4M49 D79 X 378
Nothing else on the tire inside and out, besides size, brand, ratings and warnings.
does that code make sense?

Speed is just a question of money... How fast do you want to go?
FAST, CHEAP, RELIABLE..... Pick two. Just don't pick cheap.

Wrong side of the tire... if there isn't 4 digits at the end.. check the other side.
4202 = 42nd week of 2002... 42/52=0.80*12= End of September.

It's possible the tires are from before the year 2000 as you mentioned when they only used 3 digit codes, not 4.
378 would mean 37th week of the 8th year of the decade (1997?)
That would make those fairly old tires
