It just makes sense to me that if the rubber has to stretch too much it is under tension and it gets thinner so it's easier to puncture it. I have some 700x47's and tubes for 35mm tires that don't seem to hold air as long yet the same size tube using a 32mm tire seems to hold air much longer. I don't know it it has any bearing but I have experienced this on my single speed bike too with 'narrow' tires and wider than for the tire, tubes. Then again, I've only had two or three flats and one blowout in the last 12,000 miles so maybe I don't ride enough. It just seems logical, if you have a choice, to use the most ideal combination for something as important as tires.
