NHTSA Recall ID Number :


Synopsis :

Bridgestone Americas Tire Operations, LLC (BATO) is recalling certain Firestone Destination LE3 255/60R19 tires with DOT codes 2420 through 2820 and Bridgestone Ecopia H/L 422 Plus P255/60R19 tires with DOT codes 2820 through 3120. The recalled tires may have been manufactured with a small pinhole in the upper sidewall of the outboard side of the tire. As such, these tires fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 139, "New Pneumatic Radial Tires for Light Vehicles." Tires containing a pinhole may slowly leak air, and if undetected or ignored, the continued loss of air may increase the risk of a vehicle crash. BATO will notify owners, and based on the date code and press identification number of the tire, dealers will replace the tires with a comparable replacement free of charge. The recall is expected to begin December 18, 2020. Owners may contact BATO customer service at 1-800-847-3272.
