Last 3 years or so I have been using Rivendell's Ruffy Tuffy tires.
It is an old fashioned tire made with the best ingredients modern technology
has to offer. It offers a brisk ride; but at reasonable tire pressures cushions
the bumps passably. I do lite touring these days, and this tire is big enough for that.
Btw, I must disagree with Cyclintom. The Conti tires offer significant rolling resistance; but there's more to it than that. The buttery ride comes from buttery sidewalls. Those sidewalls also flex as you pedal, sapping your energy like a vampire. Now the plain truth is that a lot more people have crossed America coast to coast to TT 2000 tires than on Rivendell tires. It's just that any newer design will be less work; even touring tires.
