From left to right: Rock Razor (new), Hans Dampf, Magic Mary (new), and Dirty Dan. Schwalbe's four "Super Gravity" aces.
The new Magic Mary was designed as one tire to rule them all. Aggressive yet fast. Weight ranges from 780-1250 grams, depending on the size and casing.
It's all about the angles. The inside edge of the outer knobs alternates between 7 and 13-degrees to make cornering more predictable and braking better. V-grooves give additional biting edges, and the 90-degree cuts in many places help with cornering and braking grip.
The Magic Mary's outer knobs have lots of rollover support. Sipes provide more traction than a solid chunk. Also note to open channel between the center and outside, which helps the tire clean itself in muddy conditions.

In 2014, Schwalbe will offer a whopping 10 tires in the 27.5 (650b) size. The Magic Mary will come in 2.35-inch x 26, 27.5, and 29-inch sizes.
Also new for 2014 is the Rock Razor. Designed for hardpack, loose over hardpack and rocky conditions, it's best suited for rear wheel use. Weight ranges from 665-965 grams.
Ramped center knobs and siped outer knobs with good support make for a quick tire that can still bite when leaned over.
Raised center knobs improve braking performance. The Rock Razor will initially only be available in a 2.35-inch width in 26 and 27.5-inch sizes. 29-inch will likely be offered in the future.
Insipired by motorcycle tire construction, the Super Gravity casing system (right) aims to bring sturdy sidewalls and puncture resistance of a DH tire (left) down to lower weights. Both share 4 sidewall layers, but the Super Gravity line uses a folding bead and is tubeless ready.
The major difference between the DH (top) and Super Gravity (bottom) is in the tread area, which has been reduced from 6 layers to 2 plus a protection layer. The change is said to make the Super Gravity tires more supple.
The combination of "Turn Up Construction" (versus the overlap in DH tires), a new apex (wedge) design, and the protection layer, known as Snake Skin, are key to the Super Gravity line.
Most Super Gravity tires are ~200 grams lighter per tire than the comparably sized DH versions. Add in the ability to go tubeless and there are some serious weight savings to be had.
Schwalbe's tire compounds and their locations take rebound resistance into serious consideration.
Damping in action. Which ball would yield a more predictable response in tire form?
At just 370 grams (26-inch), the Thunder Burt cross-country tire bridges the gap between the Racing Ralph and Furious Fred. Siped outer knobs provide additional cornering traction, and ~66 center knobs contact the ground.
The Thunder Burt will be available in 26, 27.5 and 29-inch diameters in a 2.1-inch width.
