Abstract
In bonding a prevulcanized tread strip to a tire casing with a low-temperature-vulcanizable bonding medium temporary support elements in the form of elastic rings are inserted in the circumferential tread grooves during pressing of the tread strip against the tire casing for the purposes of achieving uniform pressure over the whole tread strip and preventing distortion or movement of portions of the tread strip and/or bonding medium during the bonding operation.
