WTB decided to venture into the momentum gaining 27. 5 category, adding a brand new model to its popular, versatile Trail Boss Line. The Trail Boss TCS Light FR 27. 5 Plus Tire stands on its own among the group with burly knobs and three inches of plush width that empower it to make its own lines across terrain. WTB uses its Dual DNA rubber compound and pliant Lightweight casing to construct the tire, which is shaped in a rounded profile with defined cornering channels. The firmer center and softer sidewalls keep the tire responsive on the flats and connected to the ground while carving through switchbacks, while squared off, openly spaced lugs also lend plenty of confidence while railing corners in trail conditions ranging from slick granite to sloppy mud. As a finishing touch, the tires feature WTB's Tubeless Compatible System TCS bead for easy, reliable seating and excellent flat protection when paired with TCS sealant.
