Our family of Dirt Wizards is highly-focused – one might even say spellbound – on providing traction and control on the kinds of surfaces where nary traction nor control are to be found.

Minimum rim size for these naughty little wizards is a 35mm outer rim width. - Folding bead - Casing: 60 TPI

OFF-ROAD The Kessel is our aggressive trail, all-mountain, and enduro tire. Tall, angular lugs, an open tread pattern, and dual-compound rubber work together for exceptional grip on loose, technical terrain. Ramped center lugs keeps rolling resistance low, while our Durable and Ultra-Durable casings with sidewall and puncture protection keep you rolling. Kessel delivers predictable performance as you push your limits. HOW IT WORKS - Center lugs are tall, angular, and ramped in the front to keep rolling resistance low; a flat side on the back boosts braking traction. Siping conforms to the terrain for maximum traction, and wide spacing improves grip while shedding mud and debris. - Alternating side lugs are angled to add traction in every direction; wide, parallel siping digs into loose trail surfaces while cornering.

The latex tube is lighter, thinner and more flexible than a butyl tube, increasing your comfort, lowering your rolling resistance, and helping to prevent flats. The tube also includes a removable core Presta valve. This tire includes PPS Ganzo, a lightweight and supple Puncture Protection System placed between the tread and casing to increase resistance to punctures.

Optimized for aggressive cross country or trail riding, the Advanced Trail Casing (ATC) is lighter and more supple than either of Kenda's gravity solutions. Using sheets of Kenda's SCT fabric across the tire sidewalls and a sub-tread belt of K-Armor under the tread blocks. The K-Armor fabric has a tighter weave, resulting in the use of less rubber during the construction process, yielding a lighter tire and a casing that is supple enough to allow the knobs to flex and form under load, yet still protects from pinch flats, punctures, and cuts.
