  • Knard 26 x 3

    The Knard 26+ shares the same tread pattern as its 29+ predecessor. 26+ is pretty much the same idea as 29+, only applied to the smaller 559mm bead seat diameter we’ve all come to know as ‘the regular ass 26” wheel.’ The casing of the Knard 26+ tire is 3” wide and designed to be used with 50mm wide rims. The 26+ tire size inflates to roughly the same outer diameter as standard 27.5” (otherwise known as 650b) tires, so there’s that. The large volume of the 26+ platform adds suspension and float while also increasing traction. The profile is round and tracks well through corners and off-camber terrain. It can be used effectively and safely on rims as narrow as 35mm. The closely spaced low-block tread grips well on all types of surfaces but is most at home on dry rock and packed dirt. Availavle in 120tpi casing.

    • Bead Seat Diameter: 559mm Note: designed for 50mm wide rims. Requires minimum of 35mm wide rim to safely engage bead hook
    • Casing: 120tpi with Kevlar bead (875g)

    Knard 27.5 x 3

    Behold: the 27.5+ version of our popular, fast-rolling Knard tread pattern (bet you didn’t see that coming!) Coming in at a hearty 27.5 x 3”, it’s designed for 35–50mm rims with a bead seat diameter of 584mm (27.5˝). The 3˝ casing rolls out to 29” when inflated. That gives you all the benefits of a 29er like more ground clearance and the increased ability to roll over obstacles better with a slightly wider footprint and some extra cush. The closely spaced low-blocks of the Knard tread grips well on multiple surface types but is most at home on dry rock and packed dirt.

    • Bead Seat Diameter: 584mm
    • Rim Width: 35mm – 50mm outer dimensions
    • Casing: 60tpi, tubeless-ready bead

    Knard 29 x 3

    This is our popular, fast rolling Knard tread applied to a 29+ casing. What’s 29+? It’s a tire meant for rims with a bead seat diameter of 622mm (29˝), but large volume and ideally shaped when used on a very wide rims. In this case Knard is a 3˝ tire designed for 50mm rims. The larger diameter smooths rolling over rough ground, the increased volume adds a bit of suspension and float, the width increases traction, and the sheer size holds speed well. The profile is round and tracks well cornering and off-camber, and will remain effective on rims as narrow as 35mm. The closely spaced low-block tread grips well on multiple surface types but is most at home on dry rock and packed dirt. 27tpi and 120tpi casings available.

    • Bead Seat Diameter: 622mm Note: designed for 50mm wide rims. Requires minimum of 35mm wide rim to safely engage bead hook
    • Casing: 120tpi with Kevlar bead (980g) 27tpi with wire bead (1240g)

    Knard 650b x 41

    This is a similar Knard tread we previously introduced on a 29 x 3˝ casing, made up of low, closely spaced knobs, an effective tread for going fast over varied terrain. We chose 41mm because it’s meaty enough to conform to the ground surface, absorb irregularities and provide a decent sized contact patch. The 27, 60 and 120tpi casings do a good job and feel lively, though the 120tpi is lighter, more supple, and features a folding bead.

    • Bead Seat Diameter: 650b x 41mm 584mm Bead Seat Diameter, 41mm casing width / Note: 23–30mm recommended rim size.
    • Casing: 60 tpi with Kevlar bead (431g)

    Knard 26 x 3.8

    The same tread as our other Knard offerings, it’s a web of closely spaced blocks designed to grab terrain and hold it hostage until it’s done with it. Made on the same casing size as our Nate and Larry tires, these tires occupy a unique place in the line-up: faster, less loose-dirt-and-mud oriented than the Nate 3.8, more point-n-shoot than Larrys or Endomorphs, and definitely more dirt than Black Floyds.

    • Bead Seat Diameter: 559mm (fits rims 50–100mm wide)
    • Casing: 120tpi with Kevlar bead (1256g) 33tpi (1569g) and 27tpi with wire bead (1635g)
