The Wentworth features an innovative tread design that is both fast-rolling and mud-clearing for riding through the worst conditions without sacrificing pedaling efficiency on hardpack. The central chevrons provide straight-line speed, while the widely spaced side knobs allow you to carve through ruts and damp corners while powering thru slippery transitions. Combined with our signature Rubberforce G tread compound and new Stage 5S Armor construction, this tire provides impressive grip in the dirt and improves both ride quality and abrasion resistance compared to its predecessor.
