The application of new modified clay in the sidewall compound of truck and bus radial tire was studied.The results showed that as the amount of modified clay increased,the vulcanization rate of the compound slowed down,the hardness was basically the same,the tensile stress,tensile strength and tear strength decreasd.The amount of modified clay below 5 phr had little effect on the flexural cracking resistance of the compound.As the amount of modified clay increased,the anti-crack growth performance of the compound after aging.The sidewall compound with 10 phr modified clay could meet the durability requirements of the finished tire.
