...and found the code LC02A38
Manufactured September 1968.
Incidently, the wheel weights are GoodYear, so those insisting on Ford weights only can rethink things.
For Goodyear tires, the date is in the first two digits of the code that is cast in the sidewall from what looks like a little plate fastened to the tire mold:

First digit
M or Z =66
K or Y =67
L or T =68
J or U =69
E or W =70
H or X =71
G or S =72

Second digit
T=Jan
U=Feb
F=Mar
S=Apr
Y=May
N=Jun
P=Jul
A=Aug
C=Sep
K=Oct
E=Nov
R=Dec
