Abstract
1297408 Testing tyres; conditioning vulcanized tyres GENERAL TIRE & RUBBER CO 4 Nov 1970 [6 Nov 1969 6 Aug 1970] 52569/70 Heading B7C A method of improving the uniformity of a cured pneumatic tyre comprises (a) locating the area of the tyre at which the maximum radial force would be generated while rotating against a surface (b) positioning the tyre in an upright position with the area of maximum force in the top quadrant thereof and (c) treating the tyre in that position to reduce the magnitude of the maximum radial force variation. Such treatment does not include the physical removal from or addition of material to the tyre. The tyre may be heat treated whilst inflated or it may be merely suspended at room temperature for a sufficient period. The tyre to be treated may contain cords of nylon or polyester and after its removal from a heated vulcanizing press it may be cooled whilst held in an inflated condition.
