This article deals with the experimental investigation of the influence of tire pressure on fuel consumption and tire life in passenger cars. Using laboratory and real-world operational measurements, the dependence between tire pressure and temperature, contact patch size, tread wear, and changes in driving characteristics was analyzed. The results show that even slight deviations from the prescribed pressure can lead to increased fuel consumption, shortened tire life, and reduced driving comfort and safety. The article also draws attention to the insufficient use of pressure monitoring systems in practice and points to the economic and ecological...

Wire + Arc Additive Manufacturing (WAAM) based on Gas Metal Arc Welding (GMAW) has emerged as a cost-effective and high-deposition process for fabricating large-scale aluminum components. However, its application to non-heat-treatable aluminum 5083 remains limited by thermal-cycle in-stabilities, porosity, and non-uniform mechanical performance. This study presents an integrated experimental and artificial-intelligence framework for optimizing key GMAW parameters—welding current, wire-feed speed, and welding speed—to enhance the mechanical properties of WAAM-fabricated aluminum 5083 walls. An L9 Taguchi design was employed to quantify parameter...
