Born from the need to race in European enduro events, the Vigilante is our premier aggressive All Mountain tire, and first choice for Team WTBs Mark Weir. The square lugged open tread pattern offers stability in loose or wet terrain, while the stiff outside knobs grip at lean angles like nobodys business. With Dual DNA TCS and Gravity DNA Team Issue rubber, this is the tire to ride when you are giving it your all. TCS Tubeless Compatible System Based on UST and ETRTO standards, TCS tires feature square shaped, tubeless beads and dual durometer rubber compounds. AM and Team Issue tires feature additional reinforcement for demanding terrain.
