Could be, low psi creates more rolling resistance, which creates heat, which expands the air inside the tire, which can cause issues especially when combined with the low psi already causing the inside of the sidewall to start failing. I've seen some tires come off with under inflation wear patterns being evident on the tread face, and the inside of the carcass has tons of powdered rubber in it from being under inflated and iirc the sidewall rubs against itself under the weight of the vehicle at the pinch point. So it makes for a perfect storm.
The Firestone fiasco was brought up recently in a pm. That was lack of long term r&d. Belt separation blowouts.... Firestone blamed customers for under inflation, I guess they said ppl filled em hot, not cold...article didn't specify. Or maybe the placard on the jamb was incorrect, again the article I read didn't specify.
The Firestone fiasco was horrible tho.
