OPELIKA, AL — BFGoodrich is recalling 20,000 Land Terrain tires sold in the United States and Canada because they do not have the required tread wear indicators, according to the Associated Press on Feb.4. The tires were produced between Feb. 29 and Aug. 19, 2004, at the company's plant in Opelika, Ala., the company said in a statement Friday. The size is P235/75R15, and the mold numbers are 40381 and 40382. The recalled tires have U.S. Department of Transportation tire identification numbers that begin with DOT AN HL B411 and end with the last four digits 0904 through 3304. The DOT code is on the inner sidewall of the tire just above the wheel rim. BFGoodrich will mail notices to consumers who bought the tires and will replace them free. Consumers who believe they are affected by the recall can return to where they purchased their tires for a free inspection, the company said. The tires were made using two molds provided by a supplier that did not have the required tread wear indicators, the company said. The indicators, also known as wear bars, let drivers know when they need to replace their tires.
