Any pointers on the proper use of a Rim-Jack? I have watched a couple of demonstration videos on YouTube so I know how the tool is used in principle. Any additional tips will be helpful, as I'm sure you can spring the rim out of round with improper use of the jack. I have changed tubed tires before but never on a T so any tire mounting tips you care to pass along will be equally appreciated. The tires are 440/450-21 Firestone whitewalls.

Great!!! Thanks Bill for sending this along.
