While some manuals may appear similar for the same make and model of aircraft, each manual is unique and contains specific information about a particular aircraft, such as the equipment installed and weight and balance information. Manufacturers are required to include the serial number and registration on the title page to identify the aircraft to which the manual belongs. By purchasing this manual you agree to hold us and tradebit harmless and indemnify us from any third party claims arising from the use of this manual.
the owner has insufficient experience or
doubts his ability to do the work, all adjustments,
maintenance, and repair should be carried
out only by qualified mechanics.
In order to perform the work efficiently and
to avoid costly mistakes, read the text, thoroughly
familiarize yourself with the procedures
before starting work, and then do the work carefully
in a clean area. Whenever special tools or
equipment are specified, do not use makeshift
tools or equipment. Precision measurements
can only be made if the proper instruments are
used, and the use of substitute tools may adversely
affect safe operation.

Notice: This Aircraft Tire Care and Maintenance Manual effective 10/04 combines information from previous
Goodyear Aircraft Tire Care and Maintenance manuals and supercedes all previous manuals.

The information in this manual is designed to help aircraft owners and maintenance personnel obtain
maximum service life from their bias and radial aircraft tires. The discussions contained in this part are
designed not only to teach how to properly operate and maintain aircraft tires, but also to demonstrate why
these techniques and procedures are necessary.
Aircraft operating conditions require a wide variety of tire sizes and constructions. The modern aircraft tire
is a highly-engineered composite structure designed to carry heavy loads at high speeds in the smallest and
lightest configuration practical. Despite this, tires are one of the most underrated and least understood
components on the aircraft. The general consensus is that they are round, black, and dirty, but in reality,
they are a multi-component item consisting of three major materials: steel, rubber and fabric. By weight, an
aircraft tire is approximately 50 rubber, 45 fabric, and 5 steel. Taking this one step further, there are
different types of nylon and rubber compounds in a tire construction, each with its own special
properties designed to successfully complete the task assigned.
Goodyear aircraft tire technology includes Computer Aided Design along with Finite Element Analysis, as
well as the science of compounds and materials applications. Materials and finished tires are subjected to a
variety of laboratory, dynamometer, and field evaluations to confirm performance objectives and obtain
certification.
The manufacturing process requires the precision assembly of tight-tolerance components and a curing
process under carefully controlled time, temperature and pressure conditions. Quality assurance procedures
ensure that individual components and finished tires meet specifications.
The Goodyear Technical Center and all Goodyear Aviation Tire new and retread tire plants are ISO 9001:2000 certified.
