According to the tire manufacturer, Continental Tire the Americas (CTA), the affected tires may have an overcure condition and CTA has initiated a safety recall for these tires. According to CTA, overcured tires may experience a carcass break in the sidewall with sudden air loss or could develop a belt edge separation which could lead to partial or full tread/belt loss. These conditions may increase the risk of a crash.
