ABSTRACT OF THE DISCLOSURE It is known to mould separate halves of a vehicle tyre by injection moulding and then adhere the halves together. In this invention, a complete vehicle tyre is injection- moulded in two successive stages in the first of which the two side parts of the type are moulded and partially vulcanised be- tween a core and first outer mould part. The core together with the moulded side parts is then removed and inserted into a second outer mould part and the tread is moulded and connected to the side parts by completing the vulcanisation. This produces an integral, unitary structure and permits reinforcements to be embedded in the tyre.
