PROBLEM TO BE SOLVED: To provide a regeneration method of a tire which can manufacture easily a regenerated tire having high durability, and a precure tread for the regenerated tire. SOLUTION: The annular precure tread 10 for the regenerated tire is expanded in diameter on the outer peripheral surface 30a of a tire casing 30 and bonded. As shown in Figs. 2(a) and (b), the inner peripheral side 10a of the precure tread 10 is provided with a code structure 20 comprising at least one layer of a code layer 21 containing undulant codes 22 juxtaposed along a predetermined direction with a vibration amplitude W equal to the diameter-expansion (Fig.3) at the bonding time.
