Experimental analysis of tractor tire load and pressure effects on soil compaction

This research investigates the interaction between an 18.4R38 tractor drive wheel and soil through experimental testing. The study focuses on how variations in vertical wheel load and tire inflation pressure affect mechanical effects at the soil surface. Experiments were conducted over a range of tire pressures corresponding to different loading conditions. The results were analyzed to identify changes in permissible tire pressures and loads, which were then presented graphically to establish recommended operating limits for agricultural use. The study provides practical guidance on using the tire at both the minimum and maximum allowable pressures, noting that operating outside these limits can adversely affect tire durability and lifespan.
