Abstract
A pneumatic radial tire is made by applying a restricting member circumferentially around a cylindrical radial tire carcass. Shaping pressure inflates the carcass to a toroidal shape having a section height less than a predetermined section height so that the carcass can be enclosed by a mold for vulcanization. After vulcanization, normal inflation pressure is sufficient to further expand the restricting member and carcass to a shape having a section height greater than the predetermined section height so that the carcass may be pressed into gripping engagement with a replaceable tread belt.
