"drip a little motor oil on the lug's threads before you put the nut on. "
Some auto manufactuers recomend not putting oil on the threads.

"How come they never lubricate the lug nuts on my wheels? Wouldn't that make them easier to take off when I change a tire?
Lug nuts or studs should never be lubricated. While it may make them easier to remove, they could come off while you're driving. If you can't remove them with the equipment in your vehicle, call the GM Roadside Assistance line provided in your Owner's Manual."
I have seen other people recomend putting oil on the studs. It should not be necessary if the nuts are torqued to the correct setting.

Chocking the wheels with bricks is a good idea. In my old VW I used to carry three bricks to chock the wheels. I don't think I could have carried enough to stack under the car to do any good.
Just in case - Chocking the wheels means to stuff an object in front and behind a wheel to keep it from rolling. Jam it in between the wheel and the ground so the wheel would have to roll up and over the "brick" to go anywhere. Always try to pick a good level surface to change a tire.
For all of the people recomending hammers or jumping up and down on the tire iron. You run a very real risk of striping the edges of the lug nuts. It's difficult to keep the tire iron securely and properly placed on lug nut while you are jumping up and down on it.
A good cheater bar makes it much easier and much less likely to round off the lug nuts.
Don't forget to tighten your lug nuts in a star pattern. Improper tightening of lug nuts can lead to distorting brake rotors. If you change your tires often invest in a good torque wrench of the proper range.

Could you make a more worthless post full of non-information? Well obviously after reading some of your other posts but this one is as close to useless as they come.
