Abstract:
A pneumatic tire comprises a belt layer 7, a band layer 9, and a noise damper 10 made of a sponge material and attached to a radially inner surface TS of a tread 2. The width WA of the noise damper 10 is of from 40%-70% of a ground contacting width TW of the tread. The band layer 9 has an overlapping portion 12 in which two band plies 9A, 9B are radially overlapped; and the overlapping portion 12 covers an axially outer region of the belt layer 7 with a cover width WB of from 10%-25% the ground contacting width TW. An axially inner end 12i of the overlapping portion 12 is spaced a distance LC of from 5%-20% the ground contacting width TW from an axially outer end E of the noise damper 10.
