Abstract This research is dedicated to the investigation an‎d analysis of the factors affecting the improvement of the abrasion resistance of tires, as one of the most important engineering materials. Tires are used in a wide range of industries including transportation, automotive, industrial equipment an‎d medical due to their unique properties such as flexibility, chemical resistance an‎d high ductility. However, one of the main challenges in the long-term use of these materials is their relatively low abrasion resistance, which leads to a reduction in service life, a decrease in mechanical performance an‎d an increase in maintenance costs. Conventional approaches to improve abrasion resistance often include the addition of micro-sized fillers an‎d modifying chemicals. Despite some improvements, these methods are accompanied by limitations such as increased density, reduced flexibility an‎d undesirable changes in mechanical properties. In recent years, the development of advanced nanocomposites has been considered as a new an‎d efficient solution in improving the properties of tires. In this regard, the silica-phenolic resin nanocomposite, by taking advantage of the synergy of the unique properties of its components, has the potential to create extensive chemical an‎d physical interactions with the rubber matrix. Nano-silica, due to its high specific surface area an‎d ability to be uniformly dispersed at the nanometer scale, can create a reinforcing network structure. In addition, the phenolic resin, with its high hardness an‎d thermal stability, helps to increase stability an‎d reduce degradation under high pressure an‎d temperature conditions. The combination of these properties can significantly improve the abrasion resistance an‎d durability of the rubber, without negatively affecting the flexibility an‎d other desirable mechanical properties.
