Abstract: In this paper we carried out numerical analysis of influence angle of inclination of the substrate on the change pressure in aircraft tires in depending of change volume due to deformation. The aim of this paper is to conclude how much is the influence angle of inclination of the substrate on the change of pressure in the aircraft tires during the landing. The paper is based on numerical analysis of tire as contact problem between aircraft tire and ground, by using finite element method.

Key words: Aircraft tires, pressure, volume, finite element, hyperelasticity.
