We had our first flat yesterday in 2 years of tandem cycling, and it came in the form of a blowout. We were on a flat, even road, going around 16mph. I heard a ticking from the back wheel, and as I slowed...BLAM!!! The tube blew out the side about 3 inches from the stem, and I can see where the rubber on the outside of the tire bead is slightly damaged. I hadn't replaced the tube recently, and I'm pretty sure the tire bead was properly seated. We're running Schwalbe Marathons on Salsa Del Gado Cross rims, both of which were new last fall, and we didn't ride much over the winter. I've been inflating the rear tire to 110 psi, and the front to 100, but I realize that the Schwalbes are only rated to 95. Could that have caused the blowout? BTW, our total weight is around 360 lbs. I'm just thankful that this didn't happen on a downhill!
