Abstract
The method of designing a bead flange profile ( ) for a pneumatic tire ( ) to be mounted on a design rim ( ) as specified for the tire size has the steps of (a) selecting a design rim and a cured tire construction and bead profile ( ); (b) predicting or measuring the tire deformation upon mounting and inflation; (c) analyzing the deformation to show the compressed beat seat profile ( ) and the bead flange profile ( ) contacting the rim flange; (d) identifying any gaps between the tire ( ) and the rim ( ); (e) modifying the tire's bead flange profile ( ) to eliminate any gaps by moving selected points on the bead flange profile ( ) in proportion to the local gap sizes; (f) shifting all modified points axially inward by a distance so that the molded base width remains the same as the original profile ( ); and then (g) smoothing the connections between the modified portion and the rest of the bead profile ( ).
