This invention belongs to the field of marking tape technology, and particularly relates to a pre-formed hot-pressed marking tape adapted to tire sidewall patterns and convex / concave surfaces. It includes a supporting base layer, one side surface of which is provided with several independently arranged release functional layers. Each release functional layer has a flexible marking unit on its side facing away from the supporting base layer. The flexible marking unit has the ability to adapt to the deformation and adhesion of tire sidewall tread patterns and embossed lettering. This invention, through its self-adapting flexible marking unit design, fundamentally solves the core defect of existing ink transfer and hot stamping processes that can only create markings in blank areas of the tire sidewall. It can perfectly adapt to non-flat areas such as tire sidewall patterns and embossed lettering, eliminating the need to reserve a dedicated blank area for marking. This fully aligns with the current industry trend of personalized tires, narrow-width tires with limited blank areas on the sidewall, and the random marking of moving points, thus fully releasing the design space of the tire sidewall.
