The tyres pressures climb with heat from the air temperature, and heat from ground force, espescially high speed.

In my case, the tyre started to deflate from an incorrect seal and then came off the rim. Miracle I wasn't hurt. Miracle the car wasn't written off.

The company set up who fitted tyres ain't fitting tyres anymore I suspect. He was only young, his boss wasn't supervising when he should have been. It's the supervisors fault, not the young like.
Other cars during the day had similar hassles, but they hit the walls and were written off.
Tyres leaving the rims due to incorrect fitting.
