Not as much as you might think.
Back in the day, things were made out of heavy iron, and heavy truck, industrial equipment and tractor rims did not show much effect when hit wrong.
Grayhound buses were the only aluminum rims I knew of, and there was not a not of chrome rims, you just needed to lube them more, and be a little more seasoned with them. (car light-truck tires would brake o a tire machine)
A trick that worked was to stand with your feet on the tire to put some weight where your trying to get the bead to start opening, and round-house the hammer between your feet
It's been over 30 years since I was handy with a tire-hammer, bet I could still brake a bead with one, but I would practice on something like an old ten-hundred-twenty (10.00/20) OTR split-rim would be fun.
