A pneumatic tire for a vehicle wheel, according to which in the hollow chamber of the pneumatic tire there is arranged a hollow emergency ring or an emergency tube with one or more peripheral protrusions having running-up flanks which when moving into the respective flattened effective surface are substantially located in the elongation of an imaginary secant determined by the respective flattened effective surface.

Pneumatic tire for a vehicle wheel

An arrangement for securing the beads of a pneumatic tire in the rim therefor, according to which an annular inflatable body is located in the interior of the beaded pneumatic tire which inflatable body in non-inflated or in only slightly inflated condition has an inner diameter greater than the diameter defined by the seating surfaces of the tire. 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..
