Thanks for passing this suggestion along. I still change tires by hand with the little 6" tire levers I used in the 1950s and a heavy rubber hammer and, yes, I use very profane language when doing it.
I also try to do my tire changes on really hot, Texas summer afternoons, after the tire has sat in the sun for a few hours and is more flexible. A heat gun will do the job, but I feel it's safer for the tire to use the sun's heat. A little Windex spray on the tire bead facilitates mounting, too.
