Izmailov, A., Shevtsov, V., Lavrov, A., Godzhaev, Z. et al., "Application of the Universal Tire Characteristic for Estimating the Maximum Pressure of a Pneumatic Tractor Wheel on the Ground," SAE Technical Paper 2015-01-2760, 2015, doi:10.4271/2015-01-2760.
Maximum pressure is an essential parameter determining the degree of environmental impact of pneumatic tractor wheels on soils. The authors of the paper offer a method for determining and adjusting maximum pressure of a pneumatic tractor wheels on the supporting surface. The paper contains an analysis of the variation of maximum pressure on soils for various values of internal tire pressure and vertical load on a wheel. The above method allows parameters for systems of monitoring and adjustment of maximum pressure on soils to be set up by measuring tire flexure and adjusting it through changing the internal air pressure.
