There hasn’t been an official recall, but the Wall Street Journal reported that nearly 1 million car tires that were made in China and sold in the U.S. could be dangerously defective.

Two people were killed in summer 2006 when tread on a steel-belted radial allegedly separated, causing a van to crash.

Federal officials told the Journal the problem is that at least some of the tires lack a key feature designed to make tires more durable.

The tires in question are sold under the brand names Westlake, Telluride, Compass and YKS.
