This study investigates the thermal-oxidative pyrolysis of waste automobile tires as a route for converting secondary raw materials into valuable products. The process was carried out at 550 °C in a batch reactor, yielding gas, liquid, and solid fractions. The gas phase was found to be rich in combustible components, indicating its potential for energy recovery within the process. The liquid fraction exhibited properties suitable for further refining into fuel or chemical feedstocks, while the solid residue represented a carbon-containing material with potential application as a filler in polymer systems. Thermal analysis revealed that the degradation of tire rubber proceeds in two main stages, corresponding to devulcanization and subsequent decomposition of the carbon structure. These transformations govern the formation and distribution of pyrolysis products. The results confirm that pyrolysis of waste tires is an efficient and environmentally sound approach for waste management, offering a viable pathway for resource recovery and the production of value-added materials, including modifiers for bitumen and polymer composites
