A vehicle tire having a non-uniformly profiled tread with respect to its center, with a circumferential extending superwide groove having a width of at least 30 mm provided in one half of the tread and two further circumferential grooves which are narrower in comparison thereto and which have at most a width of 15 mm being provided in the other tread half.

Vehicle tire having non-uniformly profiled tread with respect to its center

A vehicle tire comprises a carcass ply ( ) extending between two bead regions, a tread region disposed between side walls ( ) and having a tread surface ( ) curved in the axial direction and also a breaker ( ) 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 ( ) with respect to the breaker continuously reduces, starting from the region of the tyre centre ( ), towards the breaker edges ( ) and in that the side walls ( ) are made at least substantially self-supporting.

Vehicle tire with continously reducing vertical spacing of tread surface with respect to breaker

A vehicle tire is described having at least one carcass ply extending between bead regions, a tread region ( ) and a belt arrangement ( ) disposed between the carcass and the tread as well as a tread profile provided in the tread region having at least one overwide circumferential groove ( ) disposed in particular away from the middle and on the inner side of the tire, with the tire region disposed beneath the overwide circumferential groove, which has in particular a width of more than 30 mm, being formed with additional localised reinforcement in the axial direction.
