Method for making pneumatic tire with foam noise damper

A 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;
• 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 and an abraded surface;
• and a foam noise damper disposed on the abraded surface.

• 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 an electronic device on the abraded surface.
