PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of effectively reducing void resonance noises without deteriorating a dynamic balance. SOLUTION: In this pneumatic tire 2, a plurality of tubular bodies 4 having communication holes 5 are rollably accommodated in a tire void 3. Length H of the communication hole 5 is preferably set to one integer-th of a reference length R corresponding to a half of an effective void length L(L=C/f) of a tire found from a sound speed C and a void resonance frequency f of the tire.
