On the way home from work I had a flat. I heard a thump at the rear of the car followed by a wiggle in the rear. I pulled off to find a flat right rear. I put on the spare and went to Discount tire where i purchased the tires since it was only a few blocks away. There was a puncture in the tread. At the store they said they could not repair it because a small spot of cord was visible on the inside. They also would not remount it so I could put in a plug from the outside. So I am stuck having to buy a tire. If I had known I would have gone home and plugged it myself.
GGRRRRRRRRRRRR

Liability.
Take it to a used tire place, I'm sure they'd mount it and plug it without hesitation.
Vaya con Dios!
