Abstract

A rim for a pneumatic vehicle tire, the beads of which are adapted to be mounted on the radially inner periphery of the rim. The rim has a rim ring that is provided radially inwardly with seating surfaces for the tire beads. On the lateral edges, the rim ring has essentially radially inwardly extending rim flanges. Furthermore, the rim ring is provided radially outwardly with support surfaces for emergency operation when a puncture, flat tire, etc. is encountered. In order to increase the ability to operate with a flat tire, the wall of the rim ring, in the vicinity of each of the rim flanges, is bent radially outwardly, and is then bent back axially inwardly at a radial spacing relative to the remainder of the rim ring, so that two annular supports are formed for supporting a flat tire.
