Based on reviews by the press and owners alike I plan on replacing the Kenda K892 tires that came on my Giant Sedona with some Schwable Marathon or Marathon + tires when these wear out.
These Kenda's however have proven to be an outstanding value. Very durable, and the small side blocks offer excellent grip on rough surfaces and tackling low angle ridges that are a challenge for a friends road bike's tires. Kenda makes some of the best budget tires IMO that perform WAY better then they have any right to.
But when cost isn't a factor I think the Schwalibe Marathon's are a very good value too if you want a durable tire for touring, hybrid and comfort style bikes.
