Beschreibung
Zusammenfassung:	The present invention is directed to a method for making a pneumatic tire having a foam noise damper, the pneumatic tire comprising two spaced inextensible beads; a ground contacting tread portion; a pair of individual sidewalls extending radially inward from the axial outer edges of said tread portion to join the respective beads, the axial outer edges of the tread portion defining a tread width; a supporting carcass for the tread portion and sidewalls; the method comprising the steps of: forming at least one foamed structure disposed radially inwardly of the carcass, the foamed structure comprising a co-vulcanized foamed rubber composition having a density ranging from 0.1 to 1 g/cm3; at least partially abrading the at least one foamed structure to form an abraded surface; and disposing a foam noise damper on the abraded surface.
