Abstract
A method and system for retreading a tire, whereby: the worn tread is removed from the tire to expose a lateral surface of a casing; the lateral surface of the casing is skived, thus resulting in the formation of holes and/or craters; a three-dimensional profile of the lateral surface is acquired by a three-dimensional scanner; the locations of the holes and/or craters in the lateral surface are determined by analyzing the three-dimensional profile; cement is only applied at the holes and/or craters in the lateral surface, by supplying the locations of the holes and/or craters to an automatic, electronically controlled applicator; the holes and/or craters are filled with green rubber; a green-rubber cushion and a tread strip are wound about the lateral surface of the casing; and the tire is cured.
