I'm guessing you don't index your tire? If you line up the hot patch with the valve stem, you'll know where to check the tire for debris. I've had a customer come in with 3 flats in the same tube. He checked it 3 times, I checked it in the store once, inside and out. While he selected a new tire, I half-absently mindedly went over it again. Sure enough, there was a tiny sliver of glass in one of the cracks of the tire. It had a happy life in there. He would inflate the tire, and let it sit overnight. The next day, when he would ride it, the pressure of his weight was enough to force the happy little piece of glass into the tube. Remove the pressure, and it went back into hiding in the rubber. There are 3 lessons to be learned here.
