If you look at the sidewall of your tires, you will see a range of pressure to inflate your tire to. Something like 32 to 38 lbs. I keep my tires inflated to the MAXIMUM value and sometimes 2 to 4 pounds more so that I have less rolling resistance, and a tad bit better gas milage.
If I was driving my car in the Summer time when temps reach 100 degrees or better, then I would lower my tire pressure to the lowest suggested value on the sidewall.
Always try to measure tire pressure when the car has sat overnight, or for a few hours.
I have been driving for 50 years, and by far the most trouble I have had with tires is when they are UNDERINFLATED. How much under inflated does it take to destroy a
tire? That depends on the road temp, type of tire, and how the manufacturer put it
all together. Usually 20 lbs under ideal is enough to damage the tire if it is driven long
enough.
Under inflated tires flex as they roll down the highway, and this flexing causes heat and shear forces to build up within the rubber, which in turn will cause the rubber to separate from the cord that is used to give the tire shape, support, and strength. In extreme cases the tire will literally tear itself to pieces, usually all at once.

Heat can cause gasses to expand, which means that in closed spaces like tires, the pressure can rise. If a tire's already at high pressures before, the heat may cause it to tear, or pop. Obviously, that's bad.
