Yes a tire failure can do damage. What is not true is that tire pressure is not going to increase to the point of having the tire “explode”. Running very low lower pressure (lower than 80% to 50% of what is needed to support the load can fail a tire but this type of failure is more accurately called a “Run Low Flex Blowout’ where the heat in the tire sidewall is high enough to melt the polyester body cord or if a steel body tire like large RV truck type tires the steel body cord fatigues. Tread separations have a different cause and with tire pressure increasing by about 2% for each increase in tire air temperature of 10F you would exceed the reversion temperature of rubber well before the pressure would increase by 150% which is about what would be needed to simply “explode” a tire. Tread and/or belt separations are the result of cumulative damage from some overload or some low air or excess speed that heats the belt rubber causing it to loose some of its strength. Tire rubber also looses flexibility and strength just due to age too. With this loss of strength we see a potential for microscopic cracks to form and grow over time (weeks or months not minutes)
Some of your information is correct but your understanding of tire mechanics, rubber compounding, tire engineering and design and tire failure analysis does not seem to be based on much actual experience in determining the real cause of a tire failure. I suggest you learn more of the facts by reading the blog RVTireSafety.com
It is not the “best thing you can do” to inflate each tire to its own inflation. This could lead to unpredictable handling or braking. Tire and vehicle engineers say that all tires an an axle should have the same inflation and no tire on an axle should be in an overload condition. Safe Travels -
