Abstract

An annular hollow tire 23 with an inner surface 38 having a generally positive radius of curvature includes at least one circumferentially extending rib portion 39 on the inner surface 38 with a negative radius of curvature located at an area 37 of the tire subject to high stresses to mitigate the stress concentrations in that area of the tire. The method of making the tire includes the steps of providing a tire mold 10 with a core 14 having a selected circumferentially extending portion 42 on the outer surface 19 with a negative radius of curvature for forming the rib portion 39, filling the space between the core 14 and mold parts 11, 12, 13 with an elastomeric precursor, heating to set the precursor and form the tire 23 and removing the tire 23 from the mold 10 and the core 14 from the tire 23 (Figure 1A). <IMAGE>
