Hotel & Travel Information

One of the most important safety critical components on cars, trucks, and aircraft is the pneumatic tire. Vehicle tires primarily control stopping distances on wet and dry roads or runways and strongly influence over-steer/under-steer behavior in handling maneuvers of cars and trucks. The inflated tire-wheel assembly also acts as a pressure vessel that releases a large amount of energy when catastrophically deflated. The tire can also serve as a fulcrum, both directly and indirectly, in contributing to vehicle rollover. This seminar covers these facets of tire safety phenomena. Engineering fundamentals are discussed and illustrated with numerous practical examples and case studies of current public interest.

The Pneumatic Tire, a 700-page E-book on CD, edited by Joseph Walter and Alan Gent is included in the course material.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 7 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should contact ACTAR, 800-809-3818, to request CEUs. As an ACTAR approved course, the fee for CEUs is reduced to $5.00.

Learning Objectives
After completing this seminar attendees will be able to:

  • Describe the most important performance parameters and operating conditions of pneumatic tires related to safety.
  • Use fundamental equations of engineering science to predict and/or explain tire-vehicle interactions related to safety.

Who Should Attend
This course is designed principally for technical professionals in the automobile, tire, and wheel industries and their suppliers. In addition, some case studies and examples involve truck, agriculture, and aircraft tires.

Prerequisites
An undergraduate degree in a technical field or commensurate experience is desirable.

Instructor(s): Gerald R. Potts
Dr. Potts is the Principal in GRP Consulting specializing in tire and vehicle dynamics and is an Adjunct Professor of Mechanical Engineering at the University of Akron, teaching tire and vehicle dynamics. Previously he worked for Firestone Research as a Research Scientist working on tire dynamics and developing a new Dynamics Research Laboratory and MTS Systems Corporation as Manager of Tire/Wheel Systems and headed the Flat-Trac™ test system development team. He also initiated the development of indoor tire wear test machines. Dr. Potts also served as an Associate Professor of Mechanical Engineering at the General Motors Institute (now Kettering University) teaching classes in vehicle dynamics, chassis engineering, vibrations, and instrumentation. He has also owned his own businesses where he developed tire test system controls and tire rolling resistance test machines and a laboratory high-speed uniformity tire test machine, as well as vehicle safety test systems for vehicle crash tests and component strength tests for major tire and vehicle companies around the world. Dr. Potts earned a Bachelor of Science degree in Mechanical Engineering from Wichita State University and Master’s and Ph.D. degrees in Mechanical Engineering from Kansas State University.
