You always want to torque with tires and wheels on the ground. I hand tighten with the lug wrench (or very lightly with the impact- note very lightly) when the car is jacked up. Then I jack it almost all the way down- just enough pressure to keep the tire from turning and hand torque each lug nut is a criss cross pattern as already noted. Then jack it all the way down. Very easy to do by yourself. Just make sure the jack is placed in the correct spot and is not under the body fenders or rockers. Some dealers seem to even damage some cars by jacking them up incorrectly. I shudder when I see and read about those instances on this forum.
