Two piece tire with improved tire tread belt

摘要

A two-piece tire assembly has a removable tread belt (12) for installing about the circumference of a tire carcass (14). The tread belt (12) has at least a pair of belt layers (36, 38, 40), and one layer (42) comprising inextensible reinforcing cables (44, 94, 80, 102, 114) inclined at substantially zero degrees relative to the circumferential direction of the tire assembly. The cables in zero degree ply have a tensile strength of at least 27,500 N.
