PROBLEM TO BE SOLVED: To provide an assembly of a pneumatic tire and a rim capable of preventing damage to a band-like body comprising a sponge material arranged at the inside of a tire at tire exchange or the like. SOLUTION: The assembly 1 of the pneumatic tire and the rim comprises the rim 2 and the pneumatic tire 3 attached to the rim 2. In the assembly 1, the band-like body 4 comprising the sponge material extending in a tire circumferential direction and having a volume of 0.4-20% of the whole volume of the inside of the tire is arranged at the inside of the tire surrounded by the rim 2 and the pneumatic tire 3. The band-like body 4 is made to a laterally lengthy flat shape so that a maximum thickness from a fixed surface fixed to a tire inner side surface 3i or a rim inner side surface 2i to a free surface facing the inside of the tire is 5-45 mm in a meridian cross section including a tire rotation axis, and the width of the fixed surface is larger than the thickness. In the band-like body 4, a crest 10 having a large thickness and a valley 11 having a small thickness are alternately continued in a width direction by waving the free surface in a width direction in a sine wave shape. Further, the valleys 11 having thicknesses of 1.0-15.0 mm at side edges are formed at least at both ends of the band-like body 4. COPYRIGHT: (C)2006,JPO&NCIPI
