It's true. I could have just gotten a particularly good or bad sample of either set of tires, but I think it's a decent start given the extent of the disparity.

This is absolutely true. Four of the six flats for tire A were in the last 600 miles of use. But how do you decide how many flats grouped together are significant? One flat is obviously not meaningful. Two in a week could still be coincidence....
