I have two pair of these in 700x32. One pair black with tan, one red with tan.
I have ridden them many times, almost always on a gravel/dirt rail trail.
I've never had a flat in the two or three years I've ridden them.
I've had a set of these on my bike for about a month and I've had four flats with them in that time span. My previous tires from a different company lasted over 10 years riding in the same conditions. A single errant stone and kiss your tube goodbye. Not recommended, especially at the premium price.
