The Commercial Fleet Tire Digest is a guide to reducing tire expenditures, produced each month by Al Cohn, director of New Market Development and Engineering Support for Pressure Systems International (P.S.I.). Cohn's discussions pinpoint topics

of interest to fleet operators and others concerned with tire safety, wear and cost as well as how to enhance fuel economy through tire technology and use.
Cohn, a recognized commercial vehicle tire expert, draws on his extensive experience to address subjects such as Ambient Temperature and Its Effect on Tire Pressure, Are the New Wide Base Tires Right for Your Trailers, and Over Versus Under-inflation.
A complete list of subjects covered in Volume 1 can be viewed at www.psitiredigest.com/archive.
P.S.I. is now offering the complete Volume 1 of the Commercial Fleet Tire Digest covering November-December 2006 through November/December 2007 printed and spiral bound to fleet managers to use in their operations.
This book is an excellent tool for technicians as well as drivers and anyone else responsible for controlling tire costs.
