apparently "simple" act of changing a tire in 105-110 degree heat becomes are very unpleasant experience.
Been there, done that
Take work gloves with you. Why ? Cause when you have a flat and loosen the wheel nuts and put them aside with the tools (on the hot aspahlt no less), it only takes the few minutes you bring the spare tire and try to pick the wheel nuts or wrench again, OUCH !!! They are HOT . Trust me !!
