| Abstract: |
| Selecting the same size of different brands of tires, with 50/50 mixture of nitrogen and oxygen filled and then placed in the 65 ℃ aging room to accelerate aging for 5 weeks to study the durability and changes in material properties of the tires after aging, make a comparison between different brands of tires on aging resistance. The results showed that the durable performance of tires decreased after aging and the aging resistance between different brands of tires vary greatly. The tensile strength and elongation at break of the sidewall rubber of aged tires decreased obviously while the tensile stress at specific elongation increased; and the belt layer adhesion decreased significantly after aging. Aging tires have potential safety problems and need to be caught attention. |
