Spare tire date code
 

This is the spare tire in my 69 Z. Can any of you people smarter than me tell the date code?

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

Second digit:
F = March [Months are (from 1, Jan, to 12, Dec) T,U,F,S,Y,N,P,A,C,K,E,R]

Thank you Lee. Makes sense it's an 03B car.

I have a Uniroyal tiger paw white stripe spare tire. The code on it is AJU DM242. How does that decode?

Dr Dave, wanna sell the spare? G70-15?

August 1969. That's if Uniroyal's code is anyting like Goodyears.

Thanks Lee. That makes some sense since the car was built in Oct. 1969 and it is on an FW (Monte Carlo) wheel. The tire is G70-15 but not currently for sale.
