Its not the high pressure, you have ro worry about, but the temperature of the gascompound in tire, it represents.
That tire inside temperature is somewhat related to the temperature of tire-material, if no external factors.
And tirepressure determination has as main goal not to overheat any part of tire-material when driving constantly the speed for wich the pressure is determined.

Once read that tires have teststandards, that theymust stand a 2 to 3 times the maxloadpressure ( 80 psi for E-load, then 160 to 240 psi.

My estimation is that temp in tire rises, if max used, to 140 degrF when 70 degr ambiŽnt temperature, and 160 degrF when 100 degr F ambiŽnt temperature.

Lately made a spreadsheet to calculate pressure for temperature change, and temperature for pressure change, and for wet and dry gascompound.

Then I found out that the amount of water. That can come into the tire by filling with outside air, gives mostly marginal extra rising of pressure, but gives slightly lower temperature in tire, and so of tire material, wich is even an advantage above dry air or nitrogen filling.

Found next article, wich comes to the same conclusions.
