Ran into problems when torque on lug nuts are higher than 90 ft. lbs. My 1/2 ton Ford truck lug nuts are set at 140 ft. lbs. This wrench can not loosen the lug nuts. Have to break lugs by hand. And that is with air pressure set at 90 psi. to the impact wrench. Kind of disappointed with it. I should return it. If you are going to rotate tires, find something better than this impact wrench. Only good for small things around the house. Like bicylces and toy wagon wheels.
