I had the same problem, and I now have two solutions:

1.    Go to a muffler shop - and get a piece of scrap pipe. Use it to
increase the leverage on your tire wrench. BTW: I bought a big strong tire
wrench, as I broke the original trying this technique.

2.    Buy a small bottle of ColdSpray, and get a ball-peen hammer. Spray the
lug nuts with the coldspray, and give a good sharp tangential hit with the
hammer. The bolts will snap right off!
