There is a DOT requirement for all tires must now to be date coded. The date code is a four-digit one with the first two digits being the week of the year and the last two being the year in which the tire was manufactured. Tires that are 5 years old or older can not be sold. I think this is due to the new compounds of which modern tires are made. Also, owners with tires over 5 years old should consider whether their tires are safe to use even if the thread and sidewalls look ok. Maybe this should be called the Tire Manufactures Economic Recovery Act.
For the What It Is Worth Dept.: Several years ago I bought a set of bias ply wide whitewall tires from Coker for my 1939 Cadillac 60 Special. Very soon after mounting them they started cracking where the whitewall and black sidewall met.
