摘要：
A tire exhibiting a desired design performance can be manufactured at a low cost using a precured tread having a mounting surface formed flat. In the process of manufacture, a base tire formed with a tread mounting surface having curvatures in the axial and circumferential directions of the tire and a precured tread having amounting surface formed flat, which is to be applied to the tread mounting surface of the base tire, are used. The precured tread has grooves (9) in its tread pattern surface opposite from its mounting surface. And the circumferential and axial lengths of the grooves (9) are formed shorter than desired design values, based on the differences in the circumferential and axial lengths between when the mounting surface of the tread applied to the base tire is curved along the curvatures of the tread mounting surface of the base tire and when the mounting surface of the tread is in a flat state.
