DEPARTMENT OF TRANSPORTATION NEWS. JANUARY 12, 1976

An ultrasonic testing procedure has been developed that will permit tire retreaders to select sound tire casings (in less than two minutes), which will assure longer lasting and safer recycled tires. This cost-effective (of several techniques tested) technique can inspect a tire, finding sepaerations, belt breaks and misalignments and nail holes. Recent tests on more than 100 tires (all construction types, 14"-15" sizes and various manufactures) indicate that eventual mechanical improvements can be made that will reduce this inspection time to less than one minute. It has been estimated that industrial versions of the system can be manufactured for less than $10,000 each. A demonstration, which may be scheduled for interested parties, along with the systems evaluation and all acquired technical data would be sufficient to permit the retread industry to perform all of the necessary development and marketing of the tire inspection equipment. A technical report on the new system may also be obtained.
