Details
Surly's Lou Tire is rear-specific and a massive 4.8-inches wide, giving you incredible traction and control. Put it on a 100mm-wide rim and let its aggressive tread carry you over snow and mud. A Kevlar bead and supple sidewalls help keep the weight down and provide a smooth ride.
The high thread-per-inch casing let this tire conform to the road/trail for superior cornering and comfort.
