A safety tube assembly for a pneumatic tire, the assembly including a plurality of balloons being contiguously disposed on the underside of a tread portion of the tire and an annular primary tube accommodated within the circumference of the balloons whereby each of the small balloons becomes an independent chamber interposed between the primary tube and the underside of the tread portion. Another feature of the invention is the provision of a puncture-resistant band surrounding the small balloons for dual protection against puncture of the pneumatic tire.
