Surly Big Fat Larry Tire

Surly's Big Fat Larry floats like a butterfly. Or maybe a blimp would be a better analogy. Measuring a whopping 4.7" when mounted to a 100mm rim, this tire will take you over sand, snow, and mud with no problem. Run low pressure for mind-blowing traction or pump it up for lower-rolling resistance, either way this tire has grip that would make Spiderman jealous.
