Abstract
Abstract Radial wire tire having four plies of unstretched nylon tire cord fabric disposed in the sidewalls thereof midway between the wire carcass and the outer surface of the sidewall at an angle of between 80* and 88* and extending substantially from the bead portion to the shoulder portion of the tire. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A pneumatic tire having a carcass of radial wire tire cords, a tread disposed circumferentially about said carcass, a pair of annular bead portions at the radially inner ends of said carcass, and a pair of sidewalls extending from said bead portions to said tread; said tire being characterized by a plurality of plies of tire cord fabric disposed in each sidewall and extending substantially from the bead portion to the tread portion and disposed about midway between the outer surface of the radial wire cords in said carcass and the outer surface of the sidewall and said plurality of plies having a cord angle of between about 80* and 88* and its cords having a low modulus of elasticity so that said plurality of plies do not substantially decrease the sidewall flexibility.
Claim 2
Dependent Claim
133 words
A pneumatic tire having a carcass of radial wire tire cords, a tread disposed circumferentially about said carcass, a pair of annular bead portions at the radially inner ends of said carcass, and a pair of sidewalls extending from said bead portions to said tread; said tire being characterized by a plurality of plies of tire cord fabric disposed in each sidewall and extending substantially from the bead portion to the tread portion and disposed about midway between the outer surface of the radial wire cords in said carcass and the outer surface of the sidewall and said plurality of plies having a cord angle of between about 80* and 88* and its cords having a low modulus of elasticity so that said plurality of plies do not substantially decrease the sidewall flexibility.
Claim 3
Dependent Claim
133 words
A pneumatic tire having a carcass of radial wire tire cords, a tread disposed circumferentially about said carcass, a pair of annular bead portions at the radially inner ends of said carcass, and a pair of sidewalls extending from said bead portions to said tread; said tire being characterized by a plurality of plies of tire cord fabric disposed in each sidewall and extending substantially from the bead portion to the tread portion and disposed about midway between the outer surface of the radial wire cords in said carcass and the outer surface of the sidewall and said plurality of plies having a cord angle of between about 80* and 88* and its cords having a low modulus of elasticity so that said plurality of plies do not substantially decrease the sidewall flexibility.
Claim 4
Dependent Claim
133 words
A pneumatic tire having a carcass of radial wire tire cords, a tread disposed circumferentially about said carcass, a pair of annular bead portions at the radially inner ends of said carcass, and a pair of sidewalls extending from said bead portions to said tread; said tire being characterized by a plurality of plies of tire cord fabric disposed in each sidewall and extending substantially from the bead portion to the tread portion and disposed about midway between the outer surface of the radial wire cords in said carcass and the outer surface of the sidewall and said plurality of plies having a cord angle of between about 80* and 88* and its cords having a low modulus of elasticity so that said plurality of plies do not substantially decrease the sidewall flexibility.
Claim 5
Dependent Claim
55 words
A pneumatic tire as claimed in claim 1, further including at least one belt ply disposed circumferentially about said carcass and beneath said tread and wherein said carcass ply is turned up around said bead portions and at least one ply of said plurality of plies overlaps the turned up portions of said carcass ply.
Claim 6
Dependent Claim
38 words
A pneumatic tire as claimed in claim 1, wherein said plurality of plies are comprised of tire cords having a specific stress at 7 percent elongation of at least 1.0 and not more than 2.5 grams per denier.
Claim 7
Dependent Claim
20 words
A pneumatic tire as claimed in claim 1, wherein the tire cord fabric in said plurality of plies is nylon.
Claim 8
Dependent Claim
18 words
A pneumatic tire as claimed in claim 2, wherein said cords in said plurality of plies are nylon.
