Abstract
A pneumatic tire is moulded using a mould core of cured rubber the radial sectional shape of which is the same as the internal radial sectional configuration of the finished tire. The opposite sides of the core are supported by fitting plates while a tread portion of tire is moulded onto the exposed outer periphery of the core. Thereafter the side plates are removed in turn and replaced by sidewall mould halves enabling sidewalls to be moulded against the core in contact with the tread portion.
