Filler ring for a vehicle wheel and tire assembly

In filler ring for a vehicle wheel and pneumatic tire assembly where the beads of the tire are mounted on the radially inner periphery of a wheel rim next to essentially radially inwardly extending rim flanges, with said filler ring covering a space located axially inwardly of a given rim flange, the improvement wherein:

• said filler ring comprises at least two different planes of circumferential hollow chambers, with these different planes being separated as spaced from one another via a predetermined cross-sectional contour and with said different planes of hollow chambers being superimposed on one another in a radial direction, and with each of said different planes of hollow chambers being provided with at least two hollow chambers successively arranged in an axial direction in each of said different planes overall having a total of up to six hollow chambers in each said filler ring, said predetermined cross-sectional contour of the filler ring assuring that even during slight movements of the tire bead under extreme driving conditions that the filler ring is kept from breaking away radially inwardly at specific locations and thus fully maintains the sealing effect thereof.
