OK,
I goofed!!First time in at least 70 changed tires. Yesterday, it was raining, and another tire lt rear on 2006 Prius was kaput thanks to the zillions of nails(esp roofing) and other construction debris that litters our streets.This one was in the sidewall!
It is raining, my wife has had some serious med problems, and I'm in a hurry. I put the dinky spare on, and was giving them one last little nudge. I absolutely couldn't have exerted more than about 120lbs of torque(yeah, it calls for 85lb-ft but 120 is absolutely the most I was twisting).Well, suddenly the lug lets go,and I now have a nice lug nut in my hand.
What is the easiest way to repair it? I assume I have to punch it thru, but I can't see the stud on the other side, so other than the wheel, what do I have to remove??

I'm 55 yo 180 lbs and was using an old lug wrench with 4 11" levers.I was grasping them about 10" from the center, so if I was exerting 70 lbs with each arm(unlikely) it would be 120 lb-ft total-unlikely!
Thanks,
Charlie
