Traction and grip are funny: too much and the ride is sluggish and slow; too little and you are putting the “skin side down.” WTB's Mutano is an amazingly versatile tire that rides the line between all-mountain-aggressive and XC-agile. Its mix includes an open, mud-shedding tread pattern, a fast-rolling center and large, soil-piercing outside knobs. Use these tires and expect to pick up speed and keep it no matter what gets in the way. And, you get WTB’s Tubeless Compatible System, too. It combines a lightweight casing with a UST bead and a nylon insert called Inner Peace for easy tubeless conversions, minimal weight and maximum traction.
