Tyres represent the only element which connects a vehicle with a roadway and they are one of the most important parts of the vehicle. Investigated samples from chosen agricultural tyres were placed into a degradation medium. Degradation media were chosen on the basis of their supposed application; the second criterion of the choice was operating liquids used in machines. A primary aim was defining a change of hardness of these samples; the second-rate aim was observing changes of a tyre weight. The aim of the research is an evaluation of the hardness change in surface layers of a tread depending on specific degradation environments to which the tyre is potentially exposed. The highest influence on the hardness was proved in the case of diesel oil and engine oil. Any essential influence of NPK fertilizer solution was not proved. The effect of water and a solution of NaCl on the hardness change was minimal.
