The same pictures will be sent to the manufacturer to see what they offer as a solution.

CONCLUSION....... The tool was never used with a air impact wrench but nonetheless it has its limitation and can be overworked using a 16" hand ratchet. Once the resistance of the tire bead on the rim gets too high the holding claw which should insure that the foot inserted under the rim starts twisting this imparts the same twsiting motion to the tower of the tool..... the more it twist the more the foot slips out and the more the claw bends.
I am confident that a claw made of solid steel with a greater cross section will be more resistant to the twisting action.
Bottom line ..... on some really badly rusted rim/tire it maybe wiser to resort to the various proven "cutting methods" used by members OR spend the big bucks for the professional hydraulic models or visit your local truck centre and pay the man.

Meanwhile we are going to rebuild our model to be more resistant to our heavy handed approach and keep the worst tires for the chainsaw and chisel.
