Rubber composition for all-steel tread, and preparation method thereof
A technology of rubber composition and steel tire, which is applied in the field of tire rubber materials, can solve the problem that the wear resistance and tear resistance of rubber materials are difficult to achieve a good balance, which is unfavorable for tire usability and tear resistance of rubber materials. To improve low rolling resistance, improve processability, and take into account tear resistance
