Abstract
Abstract A pneumatic vehicle tire having a tread strip and being provided with a pull-resistant belt extending substantially over the width of the tread strip and comprising pull-resistant strength members forming an acute angle with the circumferential direction of the tire, said tire also comprising a carcass with strength members extending into the vicinity of said belt, those portions of said carcass strength members which are adjacent said belt being at least locally undulated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
A pneumatic vehicle tire having a tread strip and being provided with a pull-resistant belt extending substantially over the width of the tread strip and comprising pull-resistant strength members forming an acute angle with the circumferential direction of the tire, said tire also comprising a carcass with strength members extending into the vicinity of said belt, all those portions of said carcass strength members which are adjacent said belt being at least locally undulated and free of stress, the amplitude of the locally undulated portions of said carcass strength member increasing in the direction from the marginal regions of said belt respectively of the central tire portion thereof.
Claim 2
Dependent Claim
108 words
A pneumatic vehicle tire having a tread strip and being provided with a pull-resistant belt extending substantially over the width of the tread strip and comprising pull-resistant strength members forming an acute angle with the circumferential direction of the tire, said tire also comprising a carcass with strength members extending into the vicinity of said belt, all those portions of said carcass strength members which are adjacent said belt being at least locally undulated and free of stress, the amplitude of the locally undulated portions of said carcass strength member increasing in the direction from the marginal regions of said belt respectively of the central tire portion thereof.
Claim 3
Dependent Claim
32 words
A tire according to claim 1, in which only the carcass strength member portions which are outwardly adjacent the marginal regions of said belt are in substantially straightened-out condition to extend rectilinearly.
Claim 4
Dependent Claim
33 words
A tire according to claim 1, in which those locally undulated carcass strength member portions which are radially inward in the vicinity of the central area of said belt have the largest amplitude.
Claim 5
Dependent Claim
31 words
A tire according to claim 3, in which the largest amplitude equals approximately in a range from one to three times the thickness gauge of any of the carcass strength members.
Claim 6
Dependent Claim
36 words
A tire according to claim 1, in which the wave length of the locally undulated portions of said carcass strength member decreases from the outward marginal areas of said belt inwardly to the central portion thereof.
Claim 7
Dependent Claim
36 words
A tire according to claim 1, in which the waves of said undulated portions increasing impact elasticity of said carcass strength members are all substantially parallel to the immediately adjacent portions of the tire inner surface.
Claim 8
Dependent Claim
38 words
A tire according to claim 1 which is provided with laterally spaced annular beads, and in which the strength members of the carcass are anchored radially to said beads and extend in uninterrupted manner from bead to bead.
Claim 9
Dependent Claim
68 words
A tire according to claim 1 which is provided with laterally spaced annular beads, and in which the carcass strength members comprise first radial portions respectively extending from the beads to the shoulder portion of the tire and second undulated portions extending from one shoulder portion to the other shoulder portion while overlapping with the adjacent ends of the respective adjacent first portions of said carcass strength members.
