METHOD OF TIRE TREAD PRODUCTION AND TIRE PRODUCED THEREBY

摘要

A method is provided for manufacturing tread for a tire without necessarily extruding the tread profile. The tread is created from multiple discrete parts that are cut from a sheet of uncured rubber material. The parts are joined together to create the tread, which can be applied to a tire immediate and cured to form a tire. Different treads formed from different rubber compositions may be created. The treads may also be created in varying shape and lengths with different rubber compositions used in different parts of the tread. One or more tread pieces can be applied to the same or different tire intermediates, which may be advantageous for simultaneous testing of different tread designs.
