The front wheels on my car crack cause the car sat throughout winter, so I have to put new tires on the car. My prob. is the lug nuts are tightened so much i can't get them off by hand, and i don't have an impact gun. Does anyone got any guesses to get them off? i can't drive it anywhere cause the tires are flat, but i can't put spares to drive it anywhere, i'm really stuck here

 

Have you tried using a big breaker bar? That should get it off...with a breaker bar its either that you will get them off or the stud will break with the lugnut if its seized or rusted on.
