Abstract:
1. A method for manufacturing a pneumatic tire having a noise damper comprising the steps of: preparing a vulcanized tire comprising a tread portion having an inner surface and an outer surface defining a ground contacting face, a pair of sidewall portions, a pair of bead portions, a carcass extending between the bead portions through the tread portion and sidewall portions, and a belt disposed radially outside the carcass in the tread portion, buffing the inner surface of the tread portion of the tire which surface is defined by a vulcanized rubber, the axial distance from each of the axial edges of the belt to the adjacent edge of the buffed area of the inner surface of the tread portion being more than 10.0 mm, and using a double-sided adhesive tape to fix a noise damper to the buffed inner surface, wherein the noise damper is made of a sponge material having a specific gravity of 0.005 to 0.060, and the double-sided adhesive tape has an adhesive force in a range of not less than 1.8 Newton/20 mm tape width when measured according to a T-shape separation test at 25 degrees C.
