BF Goodrich radial T/A white letters

This is the first time I’ve had a problem with this type of tire, and I’ve been buying them a while. How long?
Attached pictures are of my ‘71 T-top in my parent’s front yard in Phoenix. Fall of ‘74, I think. Sorry about the poor quality. I didn’t want to take the pictures out of the frame. That was the set of tires that taught me how to clean white letter BFG’s.
