Surly's Knard tire exists in a strange realm trail-taming of fatty wideness. The tread consists of closely spaced blocks that grab terrain and hold it hostage until they're done with it. Run low pressure for mind-blowing traction or pump it up for lower rolling resistance, either way the Knard has the grip to make Spiderman jealous.
