| Abstract: |
| The application of environmentally-friendly zinc in the tread compound of all-steel truck and bus radial tire was studied.The results showed that using an equivalent amount of environmentally-friendly zinc instead of ordinary zinc oxide for the tread compound of all-steel truck and bus radial tires，the zinc content of the compound decreased，the heat generation slightly decreased，the cutting resistance was improved，and other properties were equivalent.Compared with reference tire with ordinary zinc oxide in tread compound，the durability in room drum test of test tire with environmentally-friendly zinc in tread compound was improved.In the later stage of the road test，compared to the normal tire，the hardness of the tread crown and the wear of the tread of the road test tire were comparable，the actual performance of the test tire was good. |
