    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.

    “This book is a must-have reference for any agency that compares, collects, or potentially could collect tire track evidence. 
    “... I was pleasantly taken aback by how much I gleaned from reading this book.  I think any analyst who’s been doing this for a number of years will have the same experience.  For the experienced examiner, this book contains a great deal of information about tire manufacturing and how the various manufacturing processes can manifest themselves in the crime scene impressions ... .
    “The book is well organized and thoroughly explains key details of both the collection and comparison processes. ...  Any agency that deals with tire track evidence on a regular basis ... will benefit from reading this book and having it as a reference.
    “The book is illustrated with good quality color photographs and illustrations ...  useful tools for applying real world situations to what is being described in the book.
    “The book also contains information about the most modern manufacturing techniques, and discusses issues relating to the most recent phenomenon in tire track comparisons: digital photography.
    “...   I expect I’ll be using this book for reference for many years to come.”
