TYRE WARMER

Tyre warmer for motorbike or car wheels, in particular for motorbike or car racing competitions, which comprises a flexible elongated body (10) susceptible of assuming a closed configuration (B) ring-wrapped around the tyre (7) of a said wheel (2) with at least one lateral internal band (14) provided, arranged in internally folded position (C) for covering at least one corresponding annular portion (15) of the internal surface (5) of the rim (3). At least one elongated stiffening element (16) is provided, which is mechanically associated with a lateral edge (12A, 12B) of the internal band (14) of the flexible elongated body (10). Such stiffening element (16), when the flexible elongated body (10) is in closed position (B), is susceptible of mechanically forcing the internal band (14) into the internally folded position (C) in order to make it adhere to the corresponding annular portion (15) of the internal surface (5) of the rim (3).
