In succession to previous studies, the writers, in this paper, made a theoretical study on the stress in aspoked wheel under tangential load. For numerical examples, treating the wheel of railway rolling-stock with eight spokes, stresses in the rim, tire and spokes were calculated. As the results of these calculations the following conclusions have been drawn. Stress produced in the rim side root of spoke, especially bending stress is far larger than the stress in the tire and rim, its value being 776 kg/cm², and this is 2·2 times as large as that under vertical load. Moreover, under tangential and vertical loads, this bending stress increases to 1097 kg/cm².
