I run continental town & country. They come in 26x1.95 and 26x2.1. They're supposed to be high mileage tires so they're well suited to friction drive. They have a wide strip of smooth rubber down the middle and negative treading off to the sides so they roll really smooth and have enough bite for everything but the roughest off road riding. I very much prefer wider tires for the MB as it adds a lot of stability and comfort to the ride. I wouldn't suggest anything below 1.5in wide tires, they're fast rolling but they don't perform very well if you have to deal with bad pavement and they don't absorb bumps as well. Less surface area for scrubber drives as well, wider tires probably perform better when you're unlucky enough to encounter wet roads on a long incline.
