This 27.5" folding tire features 240 steel-carbide studs in ovalized groupings across the casing that bite into slippery winter surfaces.
Siped lugs provide additional traction, and when run at low pressure, cornering, braking, and acceleration are maximized when roads are in their least favorable conditions.
Siping creates a more conforming lug for added traction
240 concave carbide studs tear into slick surfaces
Fast rolling ramped center lugs provide decreased rolling resistance
Aggressive rear faces of center lugs provide excellent braking traction
