Surly's Knard is a 29 x 3-inch wide tire with the perfect tread for maximum traction plus low rolling resistance. It's designed for Surly's 50mm-wide Rabbit Hole rim (sold separately), and it will also play nice on rims down to about 35mm wide. But, your frame must have the clearance, Clarence.
The ExtraTerrestrial is an ultra-durable touring tire designed to provide low rolling resistance and durability on various multi-road surfaces, and the low-profile, directional tread pattern maintains traction when it’s needed. - Molded tread pattern for anti-cut propagation - Kevlar cap under the tread to protect against flats - Nylon breaker in the sidewalls for cut protection - Recommended rim width: 23 – 30mm - 29 x 2.50
A 29-inch version of Surly's high-volume, heavy-duty, off-road touring, set-it-and-forget-it ExtraTerrestrial tread. Like its 26-inch counterpart, it was designed to shine on hard pack surfaces and features an extremely low-profile, directional tread pattern that offers tons of traction with hardly any rolling resistance. With a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread, ET gives you more flat protection than you ever thought possible. - Bead Seat Diameter: 622mm - Rim Width: 19mm – 50mm outer dimensions - Casing: 60tpi, tubeless-ready bead
Called 29+ by those in the know, Surly's Dirt Wizard tire provides float, cushion, and traction like a fat bike tire, but keeps the handling fast and responsive with its 29 x 3.0-inch size. There's also a choice between a 60 or 120 threads-per-inch casing, so you can decide whether you're interested in supple or very supple tires. Intended for rims 50mm wide, its aggressive knobbies deliver excellent traction and control in corners and through loose, mixed terrain.
