A web of closely spaced blocks designed to grab terrain and hold it hostage until it’s done with it makes the Knard an amazing tire. Sky King is a huge fan and thinks they make the Surly ECR even more fun to ride.
This is Surly's 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.
