[B]REDUNDANCY[B]is the key to survival.

You cannot put too many sturdy things between the ground and the bottom of your car. Jack stands, then lower the car onto them, and then use a floor jack or your car jack as a backup. Me, I also have two sturdy wood stools that go in the right place. Excessive? I don't think so when most of this is Chinese handywork, and I am not content with a 10% failure rate. Ever wonder why many of the hydraulic floor jacks only have a 90 day guaranty?

And JohnM (adjacent), buying an over-sized jack stand will do little to change the overall failure rate. The tire is also a good idea. Do you have 2' x 2' piece of 3/4" plywood on top of it? You might also save your wheel and your rotor.
