The invention belongs to the technical field of tires, and discloses a Zhao bridge type closed non-pneumatic tire. The tire sequentially comprises a tire crown, a tire side, a bridge type supporting body and heat dissipation holes from outside to inside in the radial direction of the tire, wherein the tire crown comprises a tire tread, a crown belt layer, a first belt ply and a second belt ply; the tread comprises tread patterns and tread pattern grooves; and the bridge type supporting body comprises stand columns, main arches, auxiliary arches, large side arches and small side arches. The stand columns and the auxiliary arches communicate with the main arch and jointly support the main arch, the large side arch and the small side arch which are erected on two shoulders of the main arch and communicate with the main arch. The heat dissipation holes are punched after casting molding and are used for internal heat dissipation; the non-pneumatic tire adopts a closed design, so that sand and stone dirt is effectively prevented from entering the non-pneumatic tire. A mold pouring process is adopted for tire forming, and the bridge type supporting body is integrally formed. According tothe production process, the non-pneumatic tire is reliable in structure, good in bearing characteristic, simple in production process, capable of achieving automatic production, high in production efficiency and capable of effectively saving raw materials.
