The utility model tire building drum solves the limitation that the collapsing radius of the traditional forming drum cannot be sufficiently small by adopting the double-layered collapsing manner of the inner and outer shells, so that the collapsing radius of the building drum can reach a satisfactory collapsing radius, and the large enough diameter of technological requirements can be achieved when expanding, thus making the production process easier and faster.

Customized various tire building drums for Bias Tires, Engineering Tires, Agricultural Radial Tires, etc.
