NO. He was right.

DId you guys check the tire for whatever insulted the tube in the first place? And even if you did, it can be hard to find. I took a tire into the bike shop ... they turned it inside out and found the little sliver...

A *properly* inflated tire is significantly less prone to puncture. Underinflated tires get "pinch flats," when you hit a pothole or the like and the squishy tire gets mashed against the rim. I had a good half dozen of those before I learned. (Google "pinch flat." Hmmm... maybe not... where else could that take you )
