Analysis of tires that have experienced tread/belt detachment failures sometimes finds placement irregularities in the belt system that were not within the allowable specification limits set by the manufacturer. These may include step off variations, splice variations, dog-ears or displaced cables. Sometimes one sees liner or tool mark impressions from the manufacturing process in certain failure areas. These observed conditions have been described by some as rare, highly unusual and are with “scientific certainty” the manufacturing defect that lead to the detachment failure of a particular tire.
