2-20. GENERAL
a. Unit maintenance of tires is limited to what is prescribed in the specific vehicle manual. Check the
vehicle TM first. In most instances Unit maintenance of tires is limited to the following:
(1) Inspection and initial condition code classification.
(2) Mounting and demounting of tire/wheel assemblies from vehicles.
(3) Mounting and demounting of tires from rims.
(4) Inner tube patching.
(5) Valve core replacement.
(6) Minor, temporary string repair of tires in the tread crown area only. The tread crown area is
shown and explained in the illustrations on the following pages.
(7) Puncture repair of tires in the tread crown areas only within limits specified in Table 2-2.,
Table 2-3., and within the repair areas shown in the illustrations on the following pages.
b. Unit level tire injury repairs must be within the tread area as shown. Sidewall or shoulder injuries
can be repaired but require a complete section repair at a full service tire repair shop. The special tools,
equipment, and time needed for section repairs are not normally available at the Unit level.
c. Chemically vulcanizing tire repair materials are manufactured so that the repair requires a
minimum of time, effort, and equipment. The repair involves the cure of a layer of vulcanized rubber
(patch) .The layer of rubber capable of being vulcanized with the respective chemical fluid is usually
referred to as the chemical cushion. The chemical fluid that contains the vulcanizing agent, or accelerator,
capable of vulcanizing the chemical cushion is referred to as the vulcanizing fluid. The layer of chemical
cushion is always an intricate part of the repair. At the time of application, the chemical cushion layer
comes into contact with the vulcanizing agent and self-vulcanization, or chemical vulcanization, occurs.
