I have had these tires for a year now. The sidewalls have been cracking for a while. Now one of my tires the crack went all the way through the tire and it loses all of its air. The company has a recall on the same tire make and model, but different size, so they will not cover mine. They want to prorate my tires that are a year old. I told them this will be my last pair of Hankook tires that I buy from them.
