Well, that's only thing I have to worry about though. If I had other worries, I would have started a thread to ask for solutions. You will see anything I worry about will no longer be worried about by the end of the thread. Some say it will take 10 pages. Others say 30 pages.
Playing with the f-clamps today has failed. They are too light duty for the tyre rubber strength. Also they are unable to grip the bead rubber and kept slipping.
Next, I will lower a front brake disc on wood block on tyre. I have 375kg of press pressure available. This should work. I had a spare disc from a previous car lifting project. I will use that and bolt it to the car's disc top-hat top to top-hat top.
