Abstract
Abstract A pneumatic tire in which ring elements, as for example hollow metallic O-rings, are installed in bead or tread portions of the tire or both to serve reinforcement and/or cooling functions. In the tread area the ring elements operate in conjunction with tread perforations for a rapid distribution and rejection of heat as generated in an aircraft tire or the like.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
117 words
In a pneumatic tire having tread, side wall and bead portions, ring-like means unitarily contained in one or more portions circumferentially of the tire for reinforcement and/or cooling purposes, said ring-like means including one or more hollow ring elements in the body of the tire near the tread portion, each of said elements having vent holes therein some of which define a means providing for a flow of tire material into said ring element for anchoring purposes and others thereof providing for air flow to and from the ring element interior, said tire having its tread portion perforated to provide continuing air flow passages from the tread surface to and from the interior of said ring element.
Claim 2
Dependent Claim
117 words
In a pneumatic tire having tread, side wall and bead portions, ring-like means unitarily contained in one or more portions circumferentially of the tire for reinforcement and/or cooling purposes, said ring-like means including one or more hollow ring elements in the body of the tire near the tread portion, each of said elements having vent holes therein some of which define a means providing for a flow of tire material into said ring element for anchoring purposes and others thereof providing for air flow to and from the ring element interior, said tire having its tread portion perforated to provide continuing air flow passages from the tread surface to and from the interior of said ring element.
Claim 3
Dependent Claim
30 words
A pneumatic tire according to claim 1, characterized in that there is provided in the tread portion of the tire a plurality of said ring elements in a horizontal row.
Claim 4
Dependent Claim
111 words
In a pneumatic tire haviNg tread, side wall and bead portions, said tire having surfaces respectively defining the tire interior and exterior, ring-like means unitarily contained in one or more portions circumferentially of the tire for reenforcement and/or cooling purposes, said ring-like means including a ring element uniform in cross section and having a continuous hollow interior, the tire and ring element having aperture means communicating the ring element interior through one surface only of a portion of the tire said one surface being the wall of a pressurized portion of the interior of the tire for an internal pressurization of said ring element in conjunction with inflation of the tire.
Claim 5
Dependent Claim
111 words
In a pneumatic tire haviNg tread, side wall and bead portions, said tire having surfaces respectively defining the tire interior and exterior, ring-like means unitarily contained in one or more portions circumferentially of the tire for reenforcement and/or cooling purposes, said ring-like means including a ring element uniform in cross section and having a continuous hollow interior, the tire and ring element having aperture means communicating the ring element interior through one surface only of a portion of the tire said one surface being the wall of a pressurized portion of the interior of the tire for an internal pressurization of said ring element in conjunction with inflation of the tire.
Claim 6
Dependent Claim
31 words
In a pneumatic tire having tread, side wall and bead portions, a hollow metallic O-ring unitarily contained in one or more portions circumferentially of the tire for reenforcement and/or cooling purposes.
Claim 7
Dependent Claim
31 words
In a pneumatic tire having tread, side wall and bead portions, a hollow metallic O-ring unitarily contained in one or more portions circumferentially of the tire for reenforcement and/or cooling purposes.
Claim 8
Dependent Claim
39 words
A pneumatic tire according to claim 4 wherein said O-ring has vent holes acting as a means providing for a flow of tire material into said O-ring at circumferentially spaced locations to anchor the O-ring relatively to the tire.
Claim 9
Dependent Claim
20 words
A pneumatic tire according to claim 4, wherein said hollow metallic O-ring is in a bead portion of the tire.
Claim 10
Dependent Claim
20 words
A pneumatic tire according to claim 4, wherein said hollow metallic O-ring is in a tread portion of the tire.
Claim 11
Dependent Claim
21 words
A pneumatic tire according to claim 4, wherein hollow metallic O-rings are in both bead and tread portions of the tire.
Claim 12
Dependent Claim
48 words
A pneumatic tire according to claim 4 said tire having surfaces respectively defining the tire interior and exterior, aperture means in said tire opening through one only of said surfaces, and said O-ring having vent holes to communicate through said aperture means with the tire interior or exterior.
Claim 13
Dependent Claim
46 words
A pneumatic tire according to claim 9 an interior portion of the tire being pressurized in use, wherein aperture means in said tire opens to a pressurized portion of the tire interior for an internal pressurization of said O-ring in conjunction with inflation of the tire.
Claim 14
Dependent Claim
80 words
In a pneumatic tire having tread, side wall and bead portions, ring-like means unitarily contained in one or more portions circumferentially of the tire for reenforcement and/or cooling purposes, said ring-like means including a ring element uniform in cross section and having a continuous hollow interior, said ring element having vent holes acting as a means providing for a flow of tire material into said ring element at circumferentially spaced locations to anchor the ring element relatively to the tire.
Claim 15
Dependent Claim
80 words
In a pneumatic tire having tread, side wall and bead portions, ring-like means unitarily contained in one or more portions circumferentially of the tire for reenforcement and/or cooling purposes, said ring-like means including a ring element uniform in cross section and having a continuous hollow interior, said ring element having vent holes acting as a means providing for a flow of tire material into said ring element at circumferentially spaced locations to anchor the ring element relatively to the tire.
