Replaced the original Nexen at 5000 miles. I wanted a wider and more agressive tread, a smoother and quiet ride as the Kia Optima is on the stiff side. This tire is extremely well rated by Consumer Reports, which influenced my decision. These tires are very quiet, smooth riding, no slapping on cracks or ruts. The grip on ice and hard packed snow is amazing. I am very happy with these tires, would definitely buy again!
