<p>PROBLEM TO BE SOLVED: To provide a tire tube which eliminates the need of a rim flap and thereby prevents damage of the tube even if a gap is formed between a bead toe and a rim wheel by deformation of a tire during traveling.SOLUTION: A tire tube 30 is housed in a tire 10 assembled to a rim wheel 20 and includes: a tube body 31 extending along a tire circumferential direction; and reinforcement parts 32 which are formed along a circumferential direction of the tube body 31 and provided at both sides of the tube body 31 in a width direction when viewed in a width direction cross section. An outer peripheral surface of each reinforcement part 32 contacts with a bead inner peripheral surface 11C of the tire which is assembled to a rim.</p> |
