The application of pyrolytic carbon black in the bead heel compound of all-steel truck and bus radial tires was studied.The results showed that by replacing 5 phr carbon black N330 with 10 phr pyrolysis carbon black in the bead heel compound,the processability and physical properties of the compound were basically equivalent,the loss factor at 60 ℃ and the compression set decreased,the durability performance of finished tires were good,while the cost of the bead heel compound was effectively reduced.
