摘要：Problem to be solved: to provide a test method suitable for evaluating thedurability of the rib tear formed on the shoulder rib of the tire. This tire test methodisExtending in the circumferential directionA test method for a tire having a tread having a

plurality of ribs parallel in an axial direction;The tire assembly with the tire embedded inthe rimReference surfaceHaving a flat topA projection jig erected on the reference planeis provided.The tire assembly is lowered to be mounted on a test device configured sothat the tire tread is pressed against the upper surface of the projection jigThe presentinvention has a processing step for pressing only the shoulder rib of the tire tread ontothe upper surface of the projection jigThe upper surface of the projection jig isAn inclinedsurface inclined to the reference plane so as to lower the height toward the axialdirection from the axial direction of the tire.Diagram
