Tires

The Knard is a tire that just makes sense. With its tightly-spaced, low-block tread pattern, it provides the perfect ratio of traction and low rolling resistance. It grips well on all sorts of different surfaces and will haul some sausage on hardpack terrain or groomed trails. If you want a tire that has a little less bite and a bit more speed but don't want to sacrifice traction, look no further.

Surly's Knard is a 27.5-inch x 41mm tire with the perfect tread for maximum traction and low rolling resistance. Designed for wherever your path leads, the Knard is the tire you want beneath you as you plot your next adventure.

When you're out on a ride the last thing you want is to be limited by your tires in any way. Surly's ExtraTerrestrial tires were designed to let you ride without limits by following a simple tenet for tire design: make 'em high-volume and kick-ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off road touring tire that shines on hard pack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won't bog you down on smooth or hard surfaces. It's made to be durable and versatile and is at home on tour or on the trail. - Bead Seat Diameter: 559mm - Casing: 60tpi, tubeless-ready bead (928g)

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. Its tread is comprised of a dual row of aggressive, trail-gobbling, beveled knobs in the center and well-spaced, siped knobs to dig into loose corners. Designed to work on 50mm rims, Dirt Wizards are tall and wide, providing next-level traction and cushioning. The casings have been designed to be flexible and responsive, yet durable and supportive. Minimum rim size for these naughty little wizards is a 35mm outer rim width. - Folding bead

We named this tire for our friend Nate, who is also quite large and aggressive. This tire has a shred-your-face-off, run-over-anything, kung fu grip knobby tread pattern. The casing is round and supple. Tall, widely-spaced knobs are siped for added grip and compliance. The knobs’ wide spacing means they dig deep and still shed the crap you’re riding through. The tread wraps a little around the sides of the tire, providing good knob contour even on very wide rims, which in turn allows good off-camber traction. Similar to our beer preferences, Nate is available in black and tan. - Folding bead - Max pressure: 30psi

This is Bud, a front-specific 4.8" tire designed for 559mm (“26 inch”) rims. While our 100mm Clown Shoe Rims will offer the most ground contact and the best shape profile, Bud (and his brother, Lou) will also work on rims down to 65mm wide. Bud’s aggressive mud- and snow-shedding tread is characterized by tall (7mm), siped knobs, arranged in a pattern ideal for the unique requirements of steering and braking. A supple, durable 120tpi casing with folding Kevlar bead conforms well to ground surfaces of all types. - Folding bead - Casing: 120 TPI - Max pressure: 30psi - Weight: 1600g

Lou is the 26 x 4.8" rear-specific mate to Bud. Lou’s tread is much like Bud’s with tall knobs designed to grind, crawl, and claw its way over rooty, rocky, wet, muddy, loose, or otherwise inhospitable terrain. Lou’s tread pattern is a bit different, however, made for stability while both braking and accelerating. Its casing is durable, thin-walled, 120tpi which conforms well to the ground surface shape. - Folding Kevlar bead - Tubeless Ready
