A pneumatic vehicle tire with run-flat properties, having a tread (1), having a multi-ply belt assembly (2), having an inner ply (4) which is of air-tight form, having a carcass (3) which, in the bead region (5), is led from axially inside axially outward as a carcass turn-up (3a) around tension-resistant cores (6), and having side walls (8) within which there is arranged at least one reinforcement profile (9) which is of sickle-shaped cross section and which is of closed ring-shaped form around the circumference of the side wall, wherein the inner ply (4) does not run continuously through the tire cross section from bead region (5) to bead region (5), it rather being the case that, within the cross-sectional height (10) of the reinforcement profile (9), the inner ply is omitted; the inner ply (4a) is, in a region situated opposite the tread (1), arranged between the two upper ends (11) of the reinforcement profiles (9), and the inner ply (4a) does not cover said two ends (11) of the reinforcement profiles (9) axially at the inside.
-6. (canceled)
A pneumatic vehicle tire having run-flat properties, the pneumatic vehicle tire comprising:
The pneumatic vehicle tire as claimed in claim 1, wherein the inner layer is arranged between the two ends of the at least one reinforcing profiles, and wherein the inner layer ends in abutment with the two ends of the at least one reinforcing profiles.
The pneumatic vehicle tire as claimed in claim 1, wherein the inner layer is arranged between the two upper ends of the at least one reinforcing profiles, wherein the inner layer is led axially outward along the upper ends of the at least one reinforcing profiles, and wherein the inner layer has a contour-parallel covering of the upper ends of between 5 mm and 15 mm.
The pneumatic vehicle tire as claimed in claim 1, wherein the carcass is of a single-ply form and wherein the at least one reinforcing profile is arranged axially on the inside with respect to the carcass.
The pneumatic vehicle tire as claimed in claim 1, wherein in the bead region a further inner-layer strip that runs around the circumference of the tire in a circular ring-shaped manner is arranged at the height of a bead filler, wherein the inner-layer strip is led axially outward along a lower end of the at least one reinforcing profiles, and wherein the inner-layer strip has a contour-parallel covering of the lower end of between 5 mm and 15 mm.
The pneumatic vehicle tire as claimed in claim 1, wherein in the bead region a further inner-layer strip that runs around the circumference of the tire in a circular ring-shaped manner is arranged at the height of a bead filler, and wherein the inner-layer strip is led axially inward along a lower end of the at least one reinforcing profiles, and wherein the inner-layer strip has a contour-parallel covering of the lower end of between 5 mm and 15 mm.
