I discovered a new route yesterday that is near where I live on some very seldom traveled country roads. I love the route, its got rolling hills. Im a fairly new rider though, and on the descents, Im wondering if my tire will blow out simple because of the roads. If this did happen, would I be thrown from the bike and something catastrophic happen, or would I just roll for a bit and then stop? The roads aren't like cobblestone or anything, just enough to give me a good bit of vibration on the fast downhills (damn Mississippi roads). But if you could assuage my fears about a blowout, or warn me, it would be greatly appreciated.
