Abstract
A wheel rim portion is designed to strengthen tire-rim seating relationship by the provision of radial projections raised from each annular seat portion of the rim. Such rims are particularly useful in extending the emergency use periods of run-flat tires. The radial projections are preferably in the form of barbs, raised from the rim seat by a chiseling action, or knurls, raised from the seat by a suitable knurling tool.
