Heat the lug nuts with a butane cigarette lighter. The heat causes the nut, but less so the bolt, to expand making it easier to loosen. And, of course, loosen nuts a bit before jacking car.

This is a great idea to keep in mind (using the butane cig lighter)! My husband and I own a camper van, and got caught on the interstate with the problem of not being able to get a lug nut off. Out came my 12 volt hair dryer, and hubby heated the lug nut with that, and the nut came off. It definately was a great relief to the both of us. Your tips are the kind I love to read, thanks for posting it!
When changing a tire, put a small amount of Anti-seize lubricant on each wheel stud. The next time you have to change the tire, it will be much less difficult to loosen the lug nuts. Anti-seize lubricant is available at auto part stores.
Carry a cross shaft lug wrench in your car to use when you get a flat. It gives you greater leverage than the single shaft wrenches that come with most new cars. You can also carry a metal pipe to fit over one of the shafts for even better leverage. Use short, sharp impacts rather than applying constant pressure to loosen a stubborn nut.
