I had 700x38 GP 4 Seasons at about 90 psi - that couldn't have helped. These wheels (Campy Zonda) have about 8-9 k miles on them I think.
For theses wheels, your problem isn’t related to tires or inflation. It’s related to low spoke count concentrating too much stress in one area. More spokes would spread the load around more evenly.
