That's pretty dangerous. At least it was for Daddy. I remember him trying that when I was a kid. The jack foot slipped off the sidewall and the top of the jack flipped down and hit him in the head. Took several stitches.
Done it a bunch of times with zero issue. You have to have some common sense and keep the base in close to the wheel. I also don't squat down next to it either. My Dad always told me to keep my head out of the way. :poke:
Honestly, I don't know if I could use that big tire hammer with enough accuracy to call it "safe". Maybe you can, but I wouldn't be comfortable doing it.
