Before setting out on a cross USA trip, my son wants to put new tires on his Cannondale T2000. He will be carrying all his own gear in the rear panniers and rear rack.
Looking at the Schwalbe website, there are several choices: Marathon Supreme, Marathon XR and Marathon Racer (the stock tires on this year's Cannondale T1, replacement for the T2000). Schwalbe indicates that the Racer is their fastest touring tire, XR is an expedition tire and Supreme has a better speed and protection profile.
Looking for advise on the best suited tires for this trip.
In addition, the 2006 T2000 came with tires sized at 700 x 35C while the 2008 T1 comes with 700 x 32C. Are we better off with the wider or narrower tire? I assume the bike and the wheel will accomodate either.
