Abstract: After successful literature analysis there is a presumption, that vertical load and air pressure in tires has big impact for tractor dynamic and economic parameters. One of the most important parameters is tractive efficiency. Compared to other tractor parameters (engine, transmission efficiency) it is highly variable and influence overall efficiency a lot. The goal of this research was to find the between air pressure in tyres, vertical wheel loads and slippage. The research was performed on two different surfaces – soil, prepared for seeding and stubble-field. After complete results processing, we can say, that slip on stubble field, when pulling force is 13.26 kN, is highest, when air pressure in tires is 2,4 bar. and decreases by 19% percent, when air pressure in tires is lowered to 0,8 bar. On the stubble field, the slip is also largest, when pressure in tires is 2,4 bar. and decreases by 24% when it decreases to 0,8 bar
