1999 Grand Am lug nut problem

My wife has a 1999 Pontiac Grand Am which needs to have the tires rotated. The wheel lugs were torqued on pretty tight but my 200 pounds on the lug wrench managed to loosen them but unfortunately I cannot say the same for the aluminum wheels. They are on so tight that I cannot budge them. Any suggestions as to how to loosen them for removal would be appreciated.

Thanks.

The solution to your problem is an impact wrench. This is what air tools were designed to do. A good 1/2" impact wrench to start with is and Ingersoll Rand IR2135Ti or Ingersoll Rand IR231. Impact wrenches will make quick work of a stubborn lug nut. The impact motion of the air tool literally hammers the nut loose. You can try using a cheater bar on a lug wrench, but a good impact wrench will save some bloody knuckles.
