Have used these tires for a bit over two years now, and find them satisfactory for most conditions. I run them at close to 80psi most of the time, and down to 60psi on rough trails. Not a pure mountain bike tire by any means, but can take on most gravel, dry dirt, grass and small rocks with ease. Gets a bit squirrelly in wet conditions and larger rock. Runs very smoothly on dry roads. I am very confident on these tires as the tread and construction appear very solid and puncture resistant. Only reason I would change tires would be to go more aggressive for off-road wet and large rock conditions.
After, 3,700 miles on the Great Divide, i would recommend the Allaround over the Bite for better durability and less likely to flat in thorn country, i.e., New Mexico.
I've ridden coast to coast across America on Schwalbe tires, and I recently purchased this specific width of tire for a rail-trail tour on the Blue River, Chief Standing Bear, Homestead and Mopac rail-trails in NE Kansas and SE Nebraska. We had heard that there might be goatheads on a section of these trails, so I wanted the best protection for worry-free riding. I had a fabulous six-day tour out and back on these trails and not a single puncture. The tires also handled a rainy, wet day on the trail with absolutely no problem - this width of tire cut into the top wet layer of crushed limestone with fabulous handling (while my touring partner's wider tires floated a bit on top, making his bike harder to handle). Fabulous worry-free tire that's perfect for touring on rail-trails.
