Abstract: A rim, having a rim body with rim flanks, a rim well and a rim base, in which the flanks abut in the radially most inwardly point, and with opposed rim flanges, each extending from one of the flanks up to a radially most outwardly point, so that the rim flanges form opposed side walls with the flanks. The widest spot of the rim body lies beneath the rim well and above a horizontal centerline. The width in the widest spot is at least one quarter larger than a clear rim width between the rim flanges.
