Best tire rating for the desert heat?

Whatever you buy, watch the pressures. High pressure can be dangerous as the tire can separate from overpressure. If you put 35 pounds in in the evening and the temperature goes up to 110 the next day your tires could overinflate. If they are damaged by this the warranty will be voided, as I have seen the tire companies deny warranty due to overpressure. I think 130 degrees may be a low guess on the temperatures the tires maybe experience.
