That's not how it went down...

(Firestone exec) Lampe said the automaker's decision to set its air-pressure recommendation at a level lower than Firestone officials advised left little safety margin to guard against overloading the vehicle.

An underinflated and/or overloaded tire gets hot, not an overinflated one. The heat then caused the separations and other issues.

Ford had the spec in the manual right at the pressure rating of the tires, then you add the heat buildup and the pressure went over the line.

As a practical matter there is no over the line. Tires can take well over 100 psi, maybe approaching 200 psi before you need to worry about them bursting. A hot tire isn't going to build that much pressure.
