Hercules Tire & Rubber Company (Hercules) is recalling certain H502 radial medium tubeless truck tires, size 315/80R22.5 Load Range J, produced in the DOT week ending dates 5211 thru 2112. The affected tires may have been produced with an insufficient tire liner gauge (thickness) due to an improperly working machine. The presence of this condition may precipitate the formation of voids (U crack) which could result in early life sidewall separations, increasing the risk of a vehicle crash. Hercules will notify owners and the tires will be replaced free of charge. The safety recall is expected to begin on, or about, August 17, 2012. Owners may contact Hercules toll-free at 1-800-677-3573.
