Thank You for the info Bugs. The screw is in the middle of the tire, in between treads. I believe I picked it up close to home, as there is no color missing off of the screw. It appeared fine when I got out of the car the night before. No low air pressure warnings, basically, I didn't drive on it flat. It went flat in the garage overnight. I'm going to have some words with a different store manager today. Granted, If the chances of it coming apart at a high rate of speed is possible, I won't hesitate to replace it. Heaven knows that injuring myself, a passenger, or an innocent bystander is not worth a $200 tire. Didn't know when I bought these, that they were use once, and throw away.
