ABSTRACT:
Tire components are assembled on a tire building drum by laying a first liner on a surface of the drum, positioning first sidewall inserts below the cylindrical surface of the drum and around the drum at insert locations spaced from each end of the drum, laying a first carcass ply around the drum, positioning second inserts over the first ply at the insert locations, laying a second carcass over the first ply and the second inserts, positioning beads at each end of the drum, expanding the drum to increase the diameter of the cylindrical surface of the drum and provide shoulders at each end of the drum, turning edges of the first ply and the second ply over each of the beads, positioning a belt and tread assembly around the second ply, and contracting the drum for removal of the assembled tire components from the drum. The inserts are positioned in grooves extending radially inwardly in the outer surface of the building drum. The grooves enable thick inserts to be built into the tire sidewall while still maintaining a generally flat outer surface of the tire while on the building drum, thereby decreasing the possibility of air trapped between components of the uncured tire.
