Abstract
Abstract A self-supporting motor-vehicle tire has an outer ring supporting the tread, an inner ring adapted to be fitted to a rim or to be placed upon a hub, and supporting elements uniting the said rings. The supporting elements are in the form of honeycomb-like cells running substantially parallel to the axis of the tire, the average wall thickness of the cells being less than approximately one-thirtieth of the width of the tire, while the average cross-sectional area of the interior of a cell, expressed in cm 2 , is less than about one-tenth of the corresponding tire width measured in centimeters.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
In a self-supporting motor-vehicle tire comprising an inner ring, an outer ring and a honeycomb-cell structure coaxially supporting said outer ring on said inner ring, said outer ring being provided with tread-forming peripheral ribs, the improvement wherein the cells of said structure extend axially in a multiplicity of annular rows centered on the ring axis and the number of cells in each of said rows substantially corresponds to the number of said ribs, said cells having walls whose average thickness is less than approximately one-thirtieth of the axial width of said rings and said structure, the average cross-sectional area of the interior of each cell expressed in cm 2 being less than about one-tenth of said axial width measured in centimeters.
Claim 2
Dependent Claim
121 words
In a self-supporting motor-vehicle tire comprising an inner ring, an outer ring and a honeycomb-cell structure coaxially supporting said outer ring on said inner ring, said outer ring being provided with tread-forming peripheral ribs, the improvement wherein the cells of said structure extend axially in a multiplicity of annular rows centered on the ring axis and the number of cells in each of said rows substantially corresponds to the number of said ribs, said cells having walls whose average thickness is less than approximately one-thirtieth of the axial width of said rings and said structure, the average cross-sectional area of the interior of each cell expressed in cm 2 being less than about one-tenth of said axial width measured in centimeters.
Claim 3
Dependent Claim
24 words
The improvement defined in claim 1 wherein said cells are closed by lateral walls and are provided with ducts for the introduction of air.
Claim 4
Dependent Claim
22 words

Claim 5
Dependent Claim
14 words
