Title: Vehicle wheel
IPC: B60B21/10
Filed: 1984-09-08
Granted: 1989-05-31
Abstract: A vehicle wheel on which can be mounted a pneumatic tire which essentially includes rubber or rubber-like synthetic material, and has a carcass with load-carrying cords which are anchored in the bead regions of the tire via inextensible core rings. The wheel has a rigid rim with laterally outwardly disposed rim flanges; disposed axially inwardly of these rim flanges on the radially outer side of the rim are seating surfaces for the tire. To minimize disrupting effects on the tire tread, while at the same time improving the emergency operating conditions, a support member is disposed axially inwardly of the seating surfaces on the rim. This support member has a diameter which is greater than the diameter formed by the rim flanges. In the region of a given rim flange, the tire wall extends laterally outwardly from a given core ring in a substantially flat manner, and in particular in an angular range of from 0 DEG  to 20 DEG  relative to the axis of rotation of the tire. The carcass neutral line passes through the same region of a given rim flange in such a way as to avoid a turning point. The core rings are eccentrically disposed in their head regions in such a way that when the tire is mounted, the inner diameter of the tire in these bead regions is less than it is during mounting of the tire.
