| Abstract: |
| TPI and/or HVBR were used to replace or partly replace SBR1500 in the traditional NR/SBR1500（60/40）and SBR1712/SBR1500（60/40） tread compounds.The physical properties and dynamic viscoelasticity of various blend compounds were investigated.The results showed that the test tread compounds with TPI and/or HVBR possessed satisfactory mechanical properties，increased modulus and flex fatigue property，significantly reduced rolling resistance and dynamic heat build-up，and better wet traction，and by comparison，NR/TPI/HVBR tread compound had lower rolling resistance and heat build-up，and SBR/TPI/HVBR tread compound had better wet traction，flex fatigue property and wear resistance. |
