A pneumatic vehicle tire with at least two tread strips separated from each other by circumferential grooves and including belt-like reinforcements between the tread strips and the radial carcass while each tread strip has associated therewith a belt the width of which substantially corresponds to the width of the tread strips. Within the region of the belts, at least between these belts, there are provided thread-shaped strength carriers which together with the circumferential direction of the tire define an angle within the range of from 0.degree. to 10.degree..

Pneumatic vehicle tire with at least two tread strips arranged in spaced

A slightly bulged outwardly arched pneumatic vehicle tire having a tread which is narrow in relation to the width of the tire. The tire also has a belt which is pull-resistant in the circumferential direction of the tire and effects the lateral stabilization of the tire. Portions of the belt are arranged on both sides of and adjacent to the tread in sections of the tire sidewalls which are essentially cylindrical or slightly conical. In addition, the reinforcing inserts form the belt. Those reinforcing inserts located in the tire sidewalls form a considerably smaller angle with the circumferential direction of the tire than do those reinforcing inserts located below the tread.

Pneumatic vehicle tire

Pneumatic vehicle tires having a carcass with a tread strip centrally arranged thereon. The carcass freely spans the wheel rim and is only slightly outwardly curved when in a non-depressed condition. At its rim area the carcass is deflected by means of its arc of curvature towards the tire beads which are reinforced with pull-resistant cores. The carcass has a thickness which continuously decreases from its maximum thickness in the region of the tire bead to a fraction thereof at the edges of the tread strip. The carcass is provided with two fabric plies which are looped around the cores. Decreasing in distance between each other, the two plies extend beneath the tread strips. In the arc of curvature the two plies surround an elastic, deformable, incompressible intermediate layer which has an approximately wedge-shaped cross section.

A pneumatic tire for motor vehicles having a circumferential tread surface with molded-in grooves extending in a direction transverse to the circumferential direction of the tire, in which the grooves extend from a central circumferential tread surface section of the tire toward both lateral tire sides while following the curvature of a parabola of a second order.

Pneumatic tire for motor vehicles

A vehicle wheel having a pneumatic tire which is only slightly outwardly arched or crowned and which has a carcass and a centrally located tread strip. The tread strip has sharply defined edges and has a length approximately one third the width of the freely extended axial length of the tire body. The tire body is deflected sectionwise inwardly under a rated load in such a way that the carcass changes from a convex configuration to a concave one, in the process of which the carcass layers radially inwardly of the contact surface edges experience an angle variation of from 10.degree. to 30.degree..
