American Trucking Associations' Technology & Maintenance Council has released the fourth edition of the Council's Radial Tire Conditions Analysis Guide.

This edition, available in both CD and print versions, is the first comprehensive update of the manual since 2004. It features many updates to existing repair, retread and wear conditions as well as new conditions, such as those that pertain to wide-base tires.

The guide includes more than 200-color photographs and illustrations, and contains detailed, expert descriptions of every tire failure and service condition known to the industry, including diagonal wear, irregular wear, sidewall separations, the "zipper condition" and shoulder wear. It shows how to correct the tire failure conditions and what to do with the damaged tire.

Braswell said the Guide, written by the nation's top tire experts, is an invaluable failure analysis tool designed for fleet managers and tire professionals.

The guide is priced at $79 for TMC or ATA members and $105 for nonmembers. Discounts for quantities of 10 or more are available.
