TPMS - Tire Pressure Increase
Tire pressure increases while traveling. In researching I have seen where a 25% increase in pressure is fine. So at 65PSI I could expect to see pressure up to around around 81 and all should be good. ...

That is what I forgot in post before yours, external factors like sunshine on tire, exaustpipe pointed at tire, severe braking, etc.
When descending the mountains, and using the brakes to often, the heat of brakes, transported trough the rimms to tire inside, can rise it to boiling point of water, 100 degr C/212 degr F, with the pressure rising to 87.3psi dry and 101psi wet is more then 50% pressure rising from 65 psi at 65 degr F.
Then still dont let out air, a healty tire can stand that pressure, and tire material mayby still wont go overheated, because low speed and lesser deflection, so lesser heatproduction.
If you still think it scary on a hot day, you better use lower speed then lower the pressure ( wich you never must do, not warm, not cold).
