The aim of the present invention is to simplify the design and ensure multiple utilization of the removable tread without fastening devices, as well as to enable fast and easy mounting and demounting. The removable tread is manufactured as a ring-shaped covering with a tread pattern on the outer surface and a structure similar to the pneumatic tyre structure. At the same time the ring-shaped covering has an internal diameter essentially equal to the outer diameter of the pneumatic tyre, radial thickness within the 0.1-2.0 range of the tyre thickness in the cap area, and width lying within 0.03 - 1.0 range of the pneumatic tyre cap width. The ring-shaped covering is manufactured to enable free fitting onto the pneumatic tyre cap by reducing the pressure in the tyre below the atmospheric pressure, and its fastening onto the cap by increasing the pressure in the pneumatic tyre to at least the nominal value; and the covering is manufactured to allow multiple use and removal without damage to the pneumatic tyre and the ring-shaped covering. This result is also due to the fact that prior to mounting of the ring-shaped covering the pressure in the pneumatic tyre is reduced to below atmospheric pressure, and the covering is put freely onto at least a part of the pneumatic tyre cap, afterwards the pressure is increased to at least the nominal value and the ring-shaped coating is attached onto the pneumatic tyre cap. |
