Zenna's Sport Line is an all-season, high-performance tire that's designed for use on passenger vehicles and features twin center ribs that improve steering response. An all-season rubber compound allows for year-round use, and the Sport Line's wide grooves drain water out of the tread to reduce the risk of hydroplaning on wet roads. Additionally, the Sport Line's shoulder blocks put more rubber on the road to enhance cornering performance, even when driving at higher speeds.
