You can get booties for the bead bars. ALso get rid of the chinesium bead lift bars. They will bend.
SPend $100 for the hunter curved forged bar, and a coates nylon booty for it. I use a normal electric/pneumatic tire changer at home and no bar takes the abuse that the hunter deals with. Low pro run flats are no match for it (but a damn workout for me).
And yes, unless you are dealing with 15" steelies on a slow speed classic, a real balancer will be needed for anything 55 series and under.
If its german, will need road force balancing.
The tire bar thing that comes with the harbor freight changer will scratch your rims. You can mitigate the scratching by greasing the rim and/or polishing the bar, but it will still happen. If it's just a steel rim on a work truck then whatever... The duck head conversion for the HF changers look sweet. I got rid of my HF changer but if I got another one I would totally do the duckhead conversion. Another option would be to try a better bar like a no-mar motorcycle tire bar.
The bead breaker worked for me, some old tires will be more difficult.
Are you going to balance them yourself? FYI i've had poor results with bubble balancers. In my experience you need a balance machine for a civilized road going vehicle.
