The purpose of the present invention is to provide a retreaded tire including a case rubber using a rubber composition for tires which has a specific aggregate density and a specific composition to prevent the formation of aggregates having a relatively large particle diameter causing cracks in a rubber. Thus, a retreaded tire having high resistance against crack growth, in particular, a heavy-duty retreaded tire including one for aircrafts is provided.The retreaded tire of the present invention is characterized by including a case rubber obtained from a rubber composition in which, the integrated value of white areas by particles for diameter of 29 µm or more is 15% or less of the integrated value of white areas by particles for diameter from 3 to 57 µm in an examoination of a cross-section of the rubber composition with a dispergrader based on ASTM D7723. The rubber composition contains zinc oxide, a fatty acid, and a zinc salt of fatty acid in a total amount of 2 parts by weight or more but less than 13 parts by weight per 100 parts by weight of the rubber.
