Tire Forensic Analysis C1969

Topics: Manufacturing and Materials

This course provides a detailed description of tire failure modes, their potential causes, identification, and the sometimes-subtle nuances that go along with determination of tire failure. In addition, proper inspection techniques of tires will be discussed and samples will be available to reinforce the concepts learned.

The course is helpful for investigators and individuals who need to  explore and explain tire failures and point out the failure contributing factors. The course will help to clarify failure root cause between tire production process deviation, tire design, and service application. The course explains the most common problems /issues related to tire handling, maintenance, service applications, tire components, and design as the failure contributing factors. The course includes common failure and root cause examples on Passenger, Light Truck, Industrial, Agricultural, Specialty, Lawn and Garden, Power Sport (ATV/Quad) tires.

Learning Objectives

By attending this seminar, you will be able to:

  • Explain the methodologies of good tire inspection
  • Describe tire failure causes
  • Identify and determine root causes of tire failure

Who Should Attend

This course is extremely helpful for Accident Reconstructionists, Law Enforcement, Tire Claim and Warranty investigators and individuals who need to be able to explore and explain tire failures. Tire Process and Design Engineers, Tire Quality Engineers/Technicians and others involved in preventing tire defect related to process deviations, inspection prior to shipment to end users and performance in field service/inside tire test laboratories would also benefit from this course.

You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.

Zoran Markovic

Zoran MarkovicZoran Markovic specializes in tire design, processing, and forensic analysis. He has worked as a tire customer claim investigator analyst, reviewing failed tires in order to provide and identify the root cause of failure and able to describe the differences between process, application and design failure contributing factors. Zoran has conducted seminars to Marketing/Sales/Field Engineers on tire applications and construction criteria and common abnormalities. As Director of Testing, he developed indoor and outdoor purpose tire testing prior to production launches and troubleshooting of potential production failures. He has designed new products in compliance with DOT or ECE requirements.

Zoran is experienced in the tire production process, with the ability to trouble shoot, create or modify process specifications. He has educated tire design engineers on mathematical tire modeling approach and its tire performance benefits.

He has served as Chief Engineer Designing tires specifying appropriate components in order to satisfy tire main applications that are critical to quality parameters (CTQ) and in compliance with regulatory DOT/ECE requirements

Zoran has multiple advanced degrees:

  • BS in Mechanical Engineering – University of Sarajevo
  • MS in Mechanical Engineering – University of Zenica
  • MS in Engineering Technology – University of Memphis
  • Applied Lean Leadership Graduate certificate – University of Memphis
He has gained practical hands-on knowledge from his work experience at premier tire companies:
  • Tire Process Engineer at Titan Tire International
  • Tire Design/Process Engineer at Carlisle Tire & Wheel
