WTB defines the enduro tire with ther Vigilante. This aggressive all-mountain tire is the choice of the venerable Mark Weir when he's on the ragged edge. The square-lugged, open-tread pattern offers stability in wet, loose terrain, and sheds mud and debris easily. Tall, stiff outside knobs grip even at angles where you're dragging your bars through the dirt. WTB's TCS tires deliver the ride benefits of tubeless tires with the reduced weight of a non-UST tire, so you get the best of both worlds.
