The annular inflatable body has two reinforcing layers respectively including thread-shaped elements inclined in a left hand and right hand way so as to cross each other. The arrangement is such that in non-inflated condition of the inflatable body the thread-shaped elements form with the circumferential direction of the tire an angle of from approximately 23.degree. to 32.degree..
