I've changed countless motorcycle tires and dark sides too on my no mar manual changer over the years.
Last year my wife's car needed tires and was getting quotes of $800 plus....checking online I was able to find a nice set of Goodyear assurance tires for half the price of shop prices, $400 shipped to my door for 4 tires.
Figured I'd try, no problem! All four mounted and bubble balanced by me in an afternoon. Braking the bead was the hardest part, enter a Bead Blaster and problem solved.
This past weekend my son's girlfriend needed front tries bad, they were bald and she needed a state inspection. No one would take her car in over the weekend, shot over to Walmart, bought two new tires and had her mounted and balanced in under an hour with a manual tire changer in my basement.
Soon my truck will need tires and you bet I'll be swapping them myself.
I've saved thousands upon thousands ordering MC tires online and changing myself, and it's not just the money but the convenience of changing when I want and not having to bring the bike or wheels in and making multiple trips to a dealer. I can only dream of what it may be like having an automated changer and balancer, that sure would be nice.
