I love my Crosstrail; but, I changed the 45 OEM tires for Schwalbe Marathon Supremes in 35mm for the front, and 40mm for the back. The rear wheel was replaced with a stronger 36 spoke version, (Alex Adventurer) and has worked very well.
It goes almost anywhere, comfortably, capably, and semi quickly. Has good load capacity - and is a great do it all bike.
