What is a dangerously high tire pressure?
While you should always stay within this range, you should also never be below 20 PSI, or over 50 PSI, or you risk serious tire damage (more so than with standard overinflated or underinflated tires to a lesser degree). The dangers of overinflated tires become especially vivid when considering blowouts. A tire filled beyond its maximum psi can burst unexpectedly, primarily if it hits a pothole or debris. An underinflated tire isn’t safe either.
