Heavy duty construction for large weight 12" application vehicles. Built for machines of 14,000lbs or more e.g., BR180, BR+4, BRME, BRMP etc... This is a 14 ply rated tire with 10 actual plies. Corrects the weaknesses of other competing heavy duty 12" application tires with 1) a more durable constructed bead and 2) a more straight up and down side wall design to avoid contact with tire guides.
