Abstract
Abstract A pneumatic vehicle tire with a blet and a radial carcass, in which the carcass rims are anchored on the tire beads by being passed around the core flags folded in a U-shaped manner around the tire beads. The steel cables which are parallel to each other and form the core flags are arranged at an angle to the tire circumferential direction, and at least a portion of the free ends of the carcass rims face toward the outer surfaces of the tire side walls. Those sections of the core flags which are adjacent the interior of the tire, and those core flag sections which are adjacent the outside of the tire are symmetrically arranged with regard to the plane of symmetry of the tire which is perpendicular to the axis of rotation of the tire.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
A pneumatic vehicle tire provided with bead cores, which includes in combination a circumferential belt, a radial carcass, and core flags formed by steel cables arranged substantially parallel to each other and folded in a U-shaped manner around said bead cores, the rims of said carcass being looped around said core flags so as to anchor said carcass rims on said bead cores, and said steel cables which form said core flags extending at an acute angle inclined with regard to the tire circumferential direction of the tire and at least a part of the free ends of the carcass rims facing the outer surfaces of the tire side walls, and leg portions of said core flags which are adjacent to the interior of said tire as well as those portions of said core flags which are adjacent to the outside of said tire being symmetrically arranged with regard to the central tire plane perpendicular to the axis of rotation of said tire.
Claim 2
Dependent Claim
163 words
A pneumatic vehicle tire provided with bead cores, which includes in combination a circumferential belt, a radial carcass, and core flags formed by steel cables arranged substantially parallel to each other and folded in a U-shaped manner around said bead cores, the rims of said carcass being looped around said core flags so as to anchor said carcass rims on said bead cores, and said steel cables which form said core flags extending at an acute angle inclined with regard to the tire circumferential direction of the tire and at least a part of the free ends of the carcass rims facing the outer surfaces of the tire side walls, and leg portions of said core flags which are adjacent to the interior of said tire as well as those portions of said core flags which are adjacent to the outside of said tire being symmetrically arranged with regard to the central tire plane perpendicular to the axis of rotation of said tire.
Claim 3
Dependent Claim
43 words
A pneumatic vehicle tire in combination according to claim 1, in which the two free ends of said core flags extend in the side walls of the tire in the direction toward said belt projecting beyond the free ends of said carcass rims.
Claim 4
Dependent Claim
54 words
A pneumatic vehicle tire in combination according to claim 1, in which the free ends of the core flags extend in the side walls of the tire in the direction toward the respective adjacent tire shoulders so as to extend substantially through from one-third to one-half of the height of the tire side walls.
Claim 5
Dependent Claim
27 words
A pneumatic vehicle tire in combination according to claim 1, in which the steel cables of the core flags define with each other angles of approximately 90*.
