Provided are a tire having a small difference in a loss tangent (tan´) at a tire tread outer surface position and that at a middle position, a tread for a retread tire having an even vulcanization degree in a whole tread rubber area, a tire having the tread for the retread tire, and a method for manufacturing the tire. The tire satisfies the following formula: - 0.05 ¤ tan´ a - tan´ b / tan´ b ¤ 0.05 , where (tan´ a ) represents a loss tangent of strain at 2 % at 25 °C in a portion (a) within 1 mm deep from a tire tread outer surface in a direction perpendicular to a tread surface, and (tan´ b ) represents a loss tangent of strain at 2% at 25 °C in a portion (b) within 2 mm from a median center between a tread portion outer surface and a bottom surface in the direction perpendicular to the tread surface.
