The article describes the mechanism of occurrence of basic tone mechanical vibrations of rolling elastic wheels of the car, which is involved in the creation of noise in the cabin of the car. Sound vibrations occur in the rolling elastic wheels. They appear as a result of vertical deformation of the tyre in the contact zone. Oscillations are quasi-harmonic. Period T = 2 t = 2 L / V. the oscillation Frequency is equal to V/L. 2 the Formula to determine the forced vibration frequency of the surface elastic tires can be used in practice.
