You probably had seen this recent thread: http://www.bikeforums.net/showthread...Tire-Selection, but I thought I should point it out just in case. The injuries sounded pretty awful, and they were using the Michelin Pro Race3 in 25mm. I have no direct experience with the tires, but several folks seemed to think they were not the best choice for tandems. Not passing judgement, just wanted you to have all the info.
