Abstract: A pneumatic vehicle type for passenger vehicles or vans having at least one wide circumferential groove (1, 1?, 1?, 1??), which runs in the circumferential direction and is bounded on the tread periphery by two edge borders (1a, 1?a, 1?a, 1??a) which run parallel to one another and linearly, and has a groove base (13, 13?, 13?) as well as two groove edges (9, 10, 9?, 10?, 9?, 10?), wherein elements (11, 12, 11?12?, 11?, 12?) which project on the groove edges (9, 10, 9?, 10?, 9?, 10?) are formed alternately in the circumferential direction on one or other of the groove edges (9, 10, 9?, 10?, 9?, 10?), wherein each projecting element (11, 12, 11?, 12?, 11?, 12?) has a groove edge section (9a, 10a, 9?a, 10?a, 9?a, 10?a) lying opposite on the opposite groove edge (9, 10, 9?, 10?, 9?, 10?), which groove edge section (9a, 10a, 9?a, 10?a, 9?a, 10?a) runs least essentially in the radial direction starting at the edge border (1a, 1?a, 1?a, 1??a) as far as the groove base (13, 13?, 13?), wherein the groove base (13, 13

Abstract: A self-sealing pneumatic vehicle tire defines a tire circumference. The self-sealing pneumatic vehicle tire includes a belt assembly having a first width and defining a projection. A tread is arranged radially above the belt assembly and an airtight inner layer is arranged radially inwardly. A sealant layer applied radially internally after the pneumatic vehicle tire has been vulcanized has a second width approximately equal to the first width. The sealant layer is arranged approximately within the projection and defines an area radially above the sealant layer around the tire circumference. The inner layer is configured as a two part layer such that the inner layer does not lie approximately radially above the sealant layer in this area.
