	Coupled Silica Tread Compound The tread compound, unique to the LSR Sport, contains a homogeneous tire filler system that includes chemically-coupled precipitated silica and carbon black. The silica allows superior wet traction without sacrificing tread wear. Additionally, the compound contains an optimized polymer matrix that combines polymers of specific microstructures, allowing the compound to remain pliable even at lower temperatures. This polymer matrix further enhances wet traction while reducing hysteresis which leads to lower rolling resistance.   Spiral Wound Nylon Overwrap (S.N.O.W.) Spiral wound nylon overwrap combats centrifugal force under high-speed applications. This ability inhibits tire "growth" and maintains stability and carcass integrity across the entire speed range of the tire.   M + S RATED
