Abstract
Abstract A radial ply tire in which grooves due to wear at the edge regions of the tread are minimized. One embodiment of the tire includes a radial ply carcass, a layer of fiber-reinforced rubber material, a pair of circumferentially extending strips of fabric at the shoulder regions having cords obliquely disposed with respect to the circumference of the tire, a circumferential belt, and tread and sidewall portions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
168 words
A pneumatic tire having tread, shoulder and sidewall regions comprising: a carcass including at least one ply of fabric having members disposed substantially radially of the tire; a pair of strips of fabric over said carcass, one strip being at each shoulder region of the tire and each strip extending substantially circumferentially of the tire and extending into each sidewall region and having cord members obliquely disposed with respect to the circumference of the tire; a reinforcing belt extending substantially circumferentially of the tire over said fabric ply and over said fabric strips; fiber-reinforced elastomeric material having a multiplicity of short fibers therein and disposed partially under said belt and disposed in layered relation to said strip at each shoulder region of the tire, said fiber-reinforced material having thicker portions disposed nearer the shoulder boundaries of the tread and sidewall regions of the tire and thinner portions extending toward the central tread region of the tire; and tread, shoulder and sidewall portions of elastomeric material over said carcass.
Claim 2
Dependent Claim
168 words
A pneumatic tire having tread, shoulder and sidewall regions comprising: a carcass including at least one ply of fabric having members disposed substantially radially of the tire; a pair of strips of fabric over said carcass, one strip being at each shoulder region of the tire and each strip extending substantially circumferentially of the tire and extending into each sidewall region and having cord members obliquely disposed with respect to the circumference of the tire; a reinforcing belt extending substantially circumferentially of the tire over said fabric ply and over said fabric strips; fiber-reinforced elastomeric material having a multiplicity of short fibers therein and disposed partially under said belt and disposed in layered relation to said strip at each shoulder region of the tire, said fiber-reinforced material having thicker portions disposed nearer the shoulder boundaries of the tread and sidewall regions of the tire and thinner portions extending toward the central tread region of the tire; and tread, shoulder and sidewall portions of elastomeric material over said carcass.
Claim 3
Dependent Claim
24 words
A tire in accordance with claim 1 in which said fiber-reinforced material extends partially beyond said belt at eacH shoulder region of the tire.
Claim 4
Dependent Claim
27 words
A tire in accordance with claim 1 in which said fiber-reinforced material comprises a layer of approximately triangular cross-sectional shape at each shoulder region of the tire.
Claim 5
Dependent Claim
24 words
A tire in accordance with claim 1 in which each of said pair of strips is disposed between said fiber-reinforced material and said carcass.
Claim 6
Dependent Claim
18 words
A tire in accordance with claim 1 in which said cord members of said strips are of metal.
Claim 7
Dependent Claim
34 words
A tire in accordance with claim 1 in which said members of said strips are disposed at an angle in the range of 60* to 80* relative to the circumferential direction of the tire.
Claim 8
Dependent Claim
35 words
A tire in accordance with claim 1 in which said pair of strips individually extend under said tread portion of the tire a distance equal to approximately 3/10 of the width of said tread portion.
Claim 9
Dependent Claim
53 words
A tire in accordance with claim 1 in which said sidewall portions have inner circumferences and in which said pair of strips individually extend to points in said sidewall portions which are a distance of approximately 7/10 of the width of said sidewall portions removed from said inner circumferences of said sidewall portions.
Claim 10
Dependent Claim
168 words
A pneumatic tire having tread, shoulder and sidewall regions comprising: a carcass including at least one ply of fabric having members disposed substantially radially of the tire; a pair of strips of fabric over said carcass, one strip being at each shoulder region of the tire and each strip extending substantially circumferentially of the tire and having cord members obliquely disposed with respect to the circumference of the tire; a reinforcing belt extending substantially circumferentially of the tire over said fabric ply and over said fabric strips; a layer of fiber-reinforced elastomeric material having a multiplicity of short fibers therein and disposed partially under said belt and disposed in layered relation to said strip at each shoulder region of the tire, said layer of fiber-reinforced material extending from one shoulder region of the tire to the other and being thicker in the shoulder regions of the tire than under the central portion of said tread region; and tread, shoulder and sidewall portions of elastomeric material over said carcass.
Claim 11
Dependent Claim
168 words
A pneumatic tire having tread, shoulder and sidewall regions comprising: a carcass including at least one ply of fabric having members disposed substantially radially of the tire; a pair of strips of fabric over said carcass, one strip being at each shoulder region of the tire and each strip extending substantially circumferentially of the tire and having cord members obliquely disposed with respect to the circumference of the tire; a reinforcing belt extending substantially circumferentially of the tire over said fabric ply and over said fabric strips; a layer of fiber-reinforced elastomeric material having a multiplicity of short fibers therein and disposed partially under said belt and disposed in layered relation to said strip at each shoulder region of the tire, said layer of fiber-reinforced material extending from one shoulder region of the tire to the other and being thicker in the shoulder regions of the tire than under the central portion of said tread region; and tread, shoulder and sidewall portions of elastomeric material over said carcass.
