The Solus TA31 is Kumho's Grand Touring All-Season tire developed for the drivers of sporty coupes, sedans and crossover vehicles. It's used as Original Equipment on the Chrysler 200, Hyundai Sonata and Kia Soul urban crossover vehicles. Solus TA31 tires are designed to blend responsive handling, long wear and a comfortable ride with all-season traction, even in light snow.Kumho's all-season tread compound is molded into a five-rib symmetric design featuring a continuous center rib flanked by notched intermediate ribs and large shoulder blocks to deliver predictable handling, year-round traction and even wear. Four circumferential grooves and lateral notches promote hydroplaning resistance by evacuating water from under the footprint while engineered sipes increase the number of biting edges needed to enhance wet road and wintertime traction.The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon on top of a polyester cord casing to blend strength, durability and ride comfort.
