Abstract
A method for making tires. The tire is first formed in two or more parts from uncured rubber, in mould cavities provided with locking sprues to retain the moulded tire part in a desired section of the moulding. The mould is pressurized, at least when moulding the tire sidewalls, then opened and the moulded uncured tire parts carried in parts of the mould are brought together and joined under heat and pressure.
