+1 on the Continental Town and Country tires. I have a set of 26 X 1.9's on a Trek Navigator. They are the fifth set of tires on this bike that has over 10,000 miles put on over the past 3 years. I've had narrower tires that had higher pressure, but the Conti's have been the fastest tires by at least 2 - 3 mph, under 20 mph. I've read postings by others who've noticed the same faster rolling characteristics, going against the common axiom of skinner/higher pressure = faster. The Conti's at 55 psi are faster than the previous 1.75's that ran at 75 psi. They have good traction and seem to be wearing OK, with 800 miles on them so far. I run on both street and rocky mountain trail.
