Abstract
A pneumatic radial tire having in axial cross-section a highly curved tread is reinforced by a breaker assembly with improved resistance to breaker edge looseness. The breaker assembly includes one breaker ply which extends between two bead regions and has its edges disposed between a carcass main portion and a carcass turn-up portion. An improved single-stage method may be employed for building the tire.
