I live in southern Nevada, just outside of Las Vegas. Everybody knows Las Vegas gets hot. But to give you an idea of how hot it gets, when I park my bikes in my garage, I have to let some of the air out of the tires. I have actually had tires get hot enough the tubes pop. I don't know if it's just the rubber drying out or if it's expansion of the air due to heat that overpressurizes the tube. Either way, if I park a bike with 95-100psi in a tire and leave it long enough, I will come out to find it flat in just a few days. This has happened to me at least 3-4 times already this summer.
