A method for detecting, evaluating, and indicating a tire air pressure value. Information signals are compared with a plurality of desired value curves having a tolerance range and an average value for the atmospheric temperature, whereupon these signals are evaluated. The pressure deviation, as a function of the desired value tolerance ranges, is assigned a specific pressure state, from which an acutal air pressure state is indicated that takes into account regional and seasonal pressure and temperature influences. Furthermore, a maximum speed and a permissible speed can be determined during emergency operation, or a state of emergency operation can be determined.

Method of determining a variable air pressure value of a pneumatic

A vehicle wheel and pneumatic tire arrangement. The tire has a radial carcass anchored in the tire beads, a tread strip, respective shoulder-like extensions which are each formed by a step, are disposed on each side of the tread strip, and do not come into contact with the roadway under normal driving conditions, and a belt which extends laterally to within the vicinity of each step extension to such an extent that a given one of the belt portions which is disposed within the vicinity of a given step extension has a width equal to approximately 25-40% of the amount by which the widest part of the tire extends beyond the end of the tread strip at that given step extension. To achieve a low rolling resistance and at the same time a great travel comfort, the beads of the tire are disposed axially inwardly on the rim to such an extent that the beads are disposed completely axially inwardly of the step extensions. Furthermore, the carcass neutral line essentially conforms to the membrane theory in the region of the sidewalls of the tire.

Vehicle wheel and tire arrangement

In combination, a vehicle wheel which has a rigid, one-part rim, and a belted pneumatic tire having a single-ply or multiple-ply carcass and substantially inextensible and/or tension resistant core rings in the beads. The rim has rim flanges and, adjacent thereto, seating surfaces for the belted tire. To permit simple mounting of the tire, there is proposed that, in the position of the mounted tire, the distance from the center of a core cross-section to the bead edge facing the seating surface is greater than the distance to the axially inner bead edge, so that the core ring is eccentrically mounted in this region of the bead.

Vehicle tire and rim having tire bead rotatable into assembled condition

A pneumatic vehicle tire which has fine slits in the tread. These slits are inclined relative to the circumferential direction of the tire. In order to increase the frictional connection to the roadway, to make the wear of the tread more uniform, and in addition to be able to use mechanically stiff plates for the associated vulcanization molds, the fine slits are twisted about an at least approximately radially extending twist axis. The fine slits preferably extend continuously from their roots into the tread surface region proper.

Pneumatic vehicle tire

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 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 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..
