Abstract

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.
