Pressure Systems International (P.S.I.) is now offering a full set of Volume V (Jan-Nov/Dec 2011) Commercial Fleet Tire Digest issues as a printed spiral bound book. The Digest is a useful guide aimed at reducing tire expenditures, launched in 2007 and published 11 times a year, distributed electronically. 
 
In each issue tire veteran Al Cohn, director of new market development and engineering support for P.S.I., discusses a subject of particular 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. The printed books are "an excellent way" to have this information in your library or passed on to drivers, technicians and others. 
 
Separate books for previous years 2007 to 2010 are also available by request.  

Books can be ordered and past issues of the Commercial Fleet Tire Digest can be viewed and downloaded here. If you wish to be added to the free monthly e-mail distribution of future issues, please complete the subscription form here.
