Tire Tread and Tire Track Evidence

Police success in linking vehicles to the scene of a crime through the impressions and tracks those vehicles leave behind has long served as a successful and reliable forensic tool. The collection and forensic evaluation of that evidence, however, requires specialized knowledge, training, and expertise. Drawing from the author’s 34 years of experience, first as an FBI examiner and currently as a private consultant in the area of tire evidence, Tire and Tire Track Evidence: Recovery and Forensic Examination is the most comprehensive and up-to-date volume available on the subject. Covering all aspects of the field, the book begins with general information on the modern pneumatic tire and basic terminology. For both the crime scene technician and the forensic examiner, the author addresses information on both how to recover tire track evidence and how to photograph and cast the individual tread detail from those impressions. The book explains and illustrates the necessary information on obtaining known exemplars; tire manufacturing, and retreading tires. It explains important aspects of tires including their tread design and dimension, noise treatment, general wear and individual acquired characteristics. The author instructs on applying that knowledge while conducting a structured examination procedure, resulting in the final evaluation of evidence and report writing as well as the presentation of tire evidence in court. He provides information on databases and resources along with case examples, including the Oklahoma City bombing. Informative and useful, this book gives crime scene technicians and forensic examiners the tools to accurately and reliably collect, recover, and examine tire evidence.
