With the Grand Bois especially, when the tire starts getting seriously thin it becomes much more prone to flats. I take this as an opportunity to check the thickness by pinching the tire. When it gets down to "Damn, that's thin in the middle!" -- i.e., feels like the thickness of a few sheets of paper, even though there's no actual cord showing through -- I'll replace the tire. Usually it's pretty late in the season by the time that happens, and at that point (usually some time in November or early December) I'll take off the Cypres and replace them with Paselas for the winter season. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
