62-338,897 METHOD OF DETECTING DEFECTS IN PNEUMATIC TIRE IN NON-DESTRUCTIVE MANNER Defects such as separations formed within a pneumatic tire are detected in the non-destructive manner by rotating the inflated tire with respect to a pair of displacement sensors which are urged against an outer surface of the tire at a substantially zero pressure and a higher pressure, respectively, measuring displacement values of the sensors over one revolution of the tire, and deriving differences between displacement values at corresponding measuring points on the tire surface. The defects can be detected precisely without being affected the deformation and radial runout of the tire itself. |
