To enhance the strength of a coating film, corrosion resisting capacity and product appearance.

In a tire 10 for a rice planting machine, the attaching boss part 12 connected to an elastomer part 22 is mounted on the axle of the rice planting machine 10. The method for producing the tire 10 consists of a wheel assembling process, a coating process including corrosion-resistant processing applying corrosion-resistant processing to the integrated forming substrate 23 of the boss part 12 and the connection part 18, a substrate treatment process washing the engaging part 20 to the elastomer part 22, an adhesion treatment method applying an adhesive to the washed part, a drying process for drying the adhesive, a filling process for filling the rubber for forming the elastomer part, and a vulcanizing process.
