U.S. safety regulators say the 16-inch tires were sold under the name of Achilles Desert Hawk and Radar Radial RLT-9. Blisters can develop on the side of the Achilles tires. The Radar tires have a defective sidewall design that can cause tread separation.
The National Highway Traffic Safety Administration says both tires could lose air suddenly.
The company says in documents that it doesn't know of any crashes or injuries from the problems. The tires will be replaced free of charge starting this month. Both tires have been redesigned to fix the problem.
