  "textContent": "The present invention relates to a device carrier (1) with at least two spiked wheels (3) rotatable about a common wheel axle (2) having the following features: The spiked wheels (3) each comprise a rim (9), a tire casing (10) with a tread surface (11) and spikes (13) arranged on the tread surface (11). The tire casing (10) encloses with the rim (9) a gas-filled tire volume which, in proper operation, has a proper tire pressure that is greater than the ambient air pressure. The tread surface (11) forms a plurality of protruding crowns (16). The spikes (13) are each mounted on one of the crowns and have a crown receiver for this purpose. The crowns and the crown receivers are each shaped in such a manner that when the crown is radially inserted into the crown receiver, a crown shoulder and a receiver shoulder come into contact with one another before a crown plateau touches a receiver floor, so that when the respective spike (13) is radially clamped against the crown, the crown is squeezed in the region of the crown shoulder against the receiver shoulder, whereby a sealing surface is formed and the crown shoulder seals in an airtight manner against the receiver shoulder at the proper tire pressure.",
