The Tioga Fastr React S-Spec tire is a low profile race tire with serrated-like knobbies to maximize grip during hard gate starts, a smooth centerline and pressure sensitive side tread that increases corner traction when pushed to the limits. This design allows the tire to maintain minimal rolling resistance throughout the race without negatively affecting corner grip. The React S-Spec is finished off with a Cylex 120 tpi casing and folding bead for additional weight savings.
