Synopsis :

Yokohama Off-Highway Tires America, Inc (YOHTA) is recalling certain Alliance High Speed Rib Implement Tire 12.5L-15 FI, 11L-15FI, Primex Highway R-550 Steer and Trailer 11-22.5, Alliance 317 Implement 10.5-20 IMP, and Alliance Stubble Proof 319 SPH 11L-15FI tires. The date code portion of the Tire Identification Number (TIN) states the incorrect manufacture date on the sidewall of the tire. As such, these tires fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 119, "New Pneumatic Tires, Other than Passenger Cars." The incorrect date code hinders drivers from accurately identifying the age of the tire and makes it difficult to determine if the tire is affected by a safety recall, which can increase the risk of a crash. YOHTA will replace the affected tires, free of charge. Owner notification letters are expected to be mailed December 09, 2022. Owners may contact YOHTA's customer service at 1-800-343-3276.

Synopsis :

Zhaoqing Junhong Co., Ltd. (Zhaoquing) is recalling certain Antares Comfort A5 tires, size LT265/75R16 10PR 123/120S. The belt may separate from 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." Belt separation may lead to loss of vehicle control, increasing the risk of a crash. The remedy is currently under development. The manufacturer has not yet provided a schedule for recall notification. Owners may contact Zhaoqing's customer service at 1-758-363-7668.
