First the good: this tire has very decent all weather traction, gripping on wet or dry pavement, dirt roads, grass, packed trails and even in light snow or slush (as well as a non-studded tire can be expected to). Tread wear is excellent as well. It also resists puncture and even visible tread damage from riding over broken glass, jagged metal road debris and sharp crushed stone. While distracted by traffic I rode directly over a glass bottle bottom, when I realized what had happened I immediately pulled off onto the sidewalk, expecting to at least do a tube change (and likely walk to my destination), but instead, I couldn't even find a mark on either tire! Now the down-side: they're about as heavy as a 700x32 tire can be and the term ""supple"" has no business being used within earshot of this tire... the only good thing about the ridiculously stiff casing (aside from the amazing puncture resistance) is that you're ensured an extra helping of cardio on any ride you take with these tires mounted. The rolling resistance and ride aren't affected much by air pressure either, they roll hard and ride ""firm"" at all pressures within the recommended range.. Somewhat surprisingly they mount without any more struggle than an average wire bead tire.
