Abstract: Cargo is transported not only on the roads but also at various field conditions. Tractors with trailers are mostly used on the field conditions. The tractor is loaded drawbar pull more when transporting a bigger cargo. On drawbar pull not only slippage of the tractor depends, but also vertical loads of the driving wheels of the tractor. It is recommended to decrease the inflation pressure in the tires in order to reduce slippage. The energy losses due to slippage can be significantly reduced by selecting the optimal inflation pressure in the tires. In order to properly select tractor trailers aggregates and choose 2WD or 4WD driving mode of the tractor suitable for the field conditions it is very important to predict the slippage value in advance. In such a case, traction ratio is usually used to predict slippage. The paper deals with the influence of the inflation pressure of the driving wheels on the traction ratio of the tractor. The drawbar pull influence of the vertical loads of the driving wheels of the tractor is analyzed. Also the slippage dependencies between the drawbar pull of the tractor and the traction ratio, when driving with 2WD and 4WD modes at various different inflation pressures in the tires, are presented
