In this work, thermogravimetric (TG) and Fourier‐transform infrared spectroscopy (FTIR) were used to explore changes in the cracking process when engine oil was mixed with waste tires. The results presented herein provide a theoretical basis and technical support for the development of potential applications of tire and engine oil copyrolysis. According to the TG analysis, it was found that the pyrolysis efficiency significantly increased with increasing ratios of engine oil in the blending. The Coats–Redfern method was used to determine the kinetics of the copyrolysis reaction. It was found that the addition of engine oil reduced the activation energy of natural rubber and synthetic rubber decomposition. FTIR analysis indicated that the addition of engine oil can improve the quality of cracked products by increasing the composition of combustible gas (CH₄) in the cracked products. This study demonstrated that the pyrolysis of tires and engine oils display a strong interaction, and copyrolysis can significantly overcome the limitations of single tire cracking.
