T72 WSW 2P/4P
T73 RSW 2P/4P
T74 WSW fiberglas
T75 RSW fibreglas

So T72, T73 are likely Firestone wide oval white and red streaks.
T74, T75 Goodyear fiberglas/polyglas.

I have a '69 340,4spd Swinger BS coded T62 which is D70x14 WSW 2P/4P
I know for a fact that GG books are not 100% correct.


My survivor 69 Dart custom 318 had the original spare in the trunk on a 5.5 rim D-70-14 WSW
