Changing the oil yesterday I noticed a Phillips head sheet metal screw penetrating the tire about dead center in the valley tread where the wear bars are. I pulled it out and yes, she was a bleeder. I'm right in the middle of changing the oil so all I could do was let her leak until I finished. Knowing I had a Run-flat car tire took some of the panic out of the equation. Left the driveway with under 20 psi still in the tire and bee-lined up to Goodyear. Stuffed $15 dollars in the mechanic's pocket and drove away to ride on some errands. Checked the pressure later and still holding at 32 psi. Some mentioned a patch vs. a plug as a more comfort level of repair. I'm sticking with the plug until further notice as my " comfort " level is greatly influenced by my " convenience " level.
