An assembly of a pneumatic tire (3) and a rim (2) includes a band-like noise damper (4), having the bottom surface (4A) fixed to a tire inner surface (3i) or a rim inner surface (2i) and the upper surface (4B) facing a tire inner space (i) in the tire inner space, and extending in the tire circumferential direction. The noise damper (4) is made of a sponge having a volume in the range of from 0.4 to 20% of the entire volume of the tire inner space. In a tire meridian section, the noise damper (4) is of a laterally long, flat sectional shape having a maximum thickness value (tm) from the bottom surface (4A) to the upper surface (4B) in the range of from 5 to 45 mm and having a width (W1) of the bottom surface (4A) more than the maximum thickness value (tm). |
