The Assurance TripleTred All-Season is Goodyear's premium Passenger All-Season tire developed for the drivers of coupes, sedans and minivans looking for confident all-season traction. The Assurance TripleTred All-Season is designed with three unique tread zones to provide year-round drivability and all-season traction, even in light snow.The Assurance TripleTred All-Season's directional tread pattern features three distinct tread zones specifically tuned to deliver traction in dry, wet and wintry conditions. The Dry Zone features large shoulder blocks to provide confident maneuvering on dry pavement. The Water Zone uses sculptured Aquachannel grooves that help evacuate water and slush to increase traction on wet roads. And the Ice Zone features a unique tread compound made of innovative polymers mixed with traction-enhancing volcanic sand and glass fibers. This unique compound is molded into a continuous center rib with multiple biting edges to enhance gripping traction on slick roads, packed snow and ice. The Assurance TripleTred All-Season tread pattern also features Goodyear's Evolving Traction Grooves that begin as 1/10" wide sipes to maximize footprint contact when the tire is new, and broaden into wider lateral grooves as the tire wears. Compared to conventional sipes, Evolving Traction Grooves generate more rain, slush and snow traction longer into the tire's life.The tire's internal structure includes twin steel belts reinforced with spirally wound polyamide to blend ride quality with durability. The tire features a polyester cord casing to enhance ride comfort.
