Tire Forensic Investigation Analyzing Tire Failure 2008 Edition, August 8, 2008
Description / Abstract:
Foreword
Tire forensics is the methodical analysis of failed tires in the pursuit of and the identification of the cause(s) or root cause(s) of the disablement of a tire. A combination of science, experience, and some art goes into the research and analysis of a tire failure. By using the laws of physics, math, chemistry, and engineering, mixed with the expert's real-world tire background and experience in the design, testing, and tire development and manufacturing processes, tire forensic experts determine the most likely events that led up to and caused the tire to fail.
Unlike a forensic pathologist analyzing a body in a criminal case, a failed tire in a civil suit typically is considered evidence that cannot be dissected and destructively analyzed without agreement by all sides. The analysis by the tire expert also may not occur until years later, with a chain of custody that may or may not be tidy and with storage conditions that can be less than optimal. Given these conditions, the forensic tire expert's background, knowledge, and ability to determine pre-, during, or post-accident damage can be crucial to determining failure causation.
The same sidewall that will cut and tear during a curb scuff event can impact a road hazard to bend the wheel flange backwards and show relatively little damage on the exterior of the tire. It takes a trained eye working in a systematic fashion to find the unusual detail that leads to the root cause contributors to the failure. I say "root cause" because the type of failure should not be the end result of the investigator's work. It usually is the beginning. The goal of the tire forensic expert is to keep digging backwards, looking for root cause(s) and putting as much of the tire story together as possible.
In this book, I cover the many ways that a tire can fail and how to identify that failure. However, I will not be going into anything but minor depth in several sections on defectively manufactured tires. It is my opinion that an expert tire forensic investigator looking into manufacturing or design defects requires knowledge of not only tire failure mechanics, but also a solid grounding in several areas such as tire manufacturing, tire mechanics, testing, and tire design, as well as some familiarity with quality control parameters. The total range of parameters, how all the various pieces are supposed to fit and operate together, and what are the correct or incorrect manufacturing details in a tire will contain subtleties and nuances; thus, at times, only experience can dictate the outcome. These subtleties will make each tire its own case with particular circumstances and therefore will be covered only generally here. However, while the tire forensic expert is performing the inspection, he or she must always examine the tire with an open mind, looking for all possibilities of failure modes, including an improperly manufactured tire or a badly designed tire.
The terms "accident sequence," "pre-accident," and "post-accident" are used frequently in this book. Most tire failures do not result in vehicle damage, collisions, rollovers, and so forth. However, litigation-related tire failures tend to involve at least some vehicle damage. By using these terms, I am relating the tire conditions that are seen to the sequence of events after tire disablement, whether or not vehicle damage or an accident has occurred.
