Econo Allrounder with 26x1.5 inch Continental Top Touring tires, a kind of worn set of the old German ones, not the new Indian ones that are just too damn heavy.
For multi terrain rides, all tire choices are a compromise. I had been running small knob, 1.7 inch width knobbies on this bike that weighed about the same as the Contis; but they were amazingly slow rolling on pavement despite their continuous center strip; I pulled them off last weekend. The Contis roll a lot better on pavement, but are a little sketchy on the edge of cambered dirt roads where gravel has gathered towards the outer edges.
Multiple terrain rides are, as always, a blast. I look forward to northern NM touring on some forest service dirt roads this summer, if all goes as planned.
