So pumping a tire up to the maximum pressure on a cold morning, and leaving it exposed to the hot sun can result in a blow out even with a good tire with no defects. I think some brands of tires are tougher than others. Some would be able to handle pressures significantly above their rated maximum pressure without problems.
That is an issue that has long confused me - why do we inflate tires to a set pressure independent of our weight? One of my lecturers at college would apply some colored chalk to an area of his tires, ride over a sheet of newspaper and measure the width. Surely the optimum tire pressure must relate to the actual loads on the tire.
