Abstract

A vehicle tire comprises a carcass ply (1) extending between two bead regions, a tread region disposed between side walls (7,8) and having a tread surface (6) curved in the axial direction and also a breaker (5) reinforcing the tread region and arranged between the carcass ply and tread region, characterised in that in the normally inflated state of the tyre mounted on a tyre rim, the vertical spacing of the tread surface (6) with respect to the breaker continuously reduces, starting from the region of the tyre centre (3), towards the breaker edges (13, 14) and in that the side walls (7, 8) are made at least substantially self-supporting.
