REVIEW AND ANALYSIS OF OVERHEATING FACTORS IN LARGE-SIZE TIRES

Abstract

The article addresses the pressing issue of overheating in large-size tires of quarry dump trucks operating in hot climates. The elevated temperatures inside the tires, resulting from movement, high loads, and intensive use, lead to accelerated rubber wear, delamination, the formation of internal defects, and premature tire failure. Based on an analysis of scientific literature, technical documentation, and experimental data, the critical role of temperature in reducing tire lifespan has been confirmed. Special attention is given to practical and design measures aimed at reducing thermal load. These include: improving tire design, applying additional insulation layers to the inner surface of the tires, using gas mixtures with optimal thermal conductivity properties (particularly nitrogen and argon mixtures), and installing built-in pressure and temperature sensors for real-time monitoring of tire condition. Additionally, production recommendations on speed limits, permissible loads, and driving modes are discussed. The conclusion emphasizes the need for a comprehensive approach and further research aimed at enhancing tire durability and reducing operational risks when using quarry equipment in hot and arid climates. The importance of collaboration between equipment manufacturers, operators, and the scientific community in developing optimal solutions is highlighted
