The Proxes STIII is formulated with an all season, silica enhanced tread compound that lowers rolling resistance while maximizing wet traction capabilities. This compound forms into a highly directional tread design with arrowhead tapers that maximize block stiffness and enhance lateral tracking. Directional shoulder blocks improve ride stability and braking performance while the offset design reduces road noise. This tire is equipped with multi-wave sipes that combat irregular wear as well as to reduce excess noise. Internally, the Proxes STIII is reinforced with a rigid bead filler and a jointless bead wire that optimize handling responsiveness. This tire is further protected with a stiff casing that further decreases rolling resistance and amplifies handling. A set of twin steel belts pitch in to reinforce the tire while also bolstering comfort levels and stability during acceleration.
