Hadn't heard about this one. From the Maryland attorney general's office:

"Attorney General Douglas F. Gansler is warning consumers about potentially dangerous tires that may have been sold to Maryland drivers and could create a potential safety hazard for those riding in light trucks, sports utility vehicles, and vans equipped with the tires. The tires were manufactured by the Chinese tire company, Hangzhou Zhongce Rubber Co., and imported into the United States by Foreign Tire Sales, Inc. (FTS) of Union, New Jersey. The affected tires may be susceptible to tread separation, which can cause serious accidents."
