Unit maintenance level should not attempt any repair to the sidewall of pneumatic tires unless
the repair person has been trained and has the tools to do it properly. Injuries sustained in the
sidewall or shoulder of the tire require special tools and training to ensure tire integrity.
Repairing pneumatic tubeless tires by using either the repair kit or inserting a plug
from outside a mounted tire is an acceptable TEMPORARY repair ONLY. Temporary tire
repairs are acceptable when there is insufficient time or inadequate facilities to perform a
complete tire repair.
The following procedure is the only acceptable method of complete tire repair.
1. Inspect tire for any puncturing objects.
2. Check the injured area and paragraphs 2-21 through 2-23 to see if it injury falls within the tread crown
area and determine if it's repairable.
3. Remove any puncturing objects and mark an area slightly larger than the injury, on the inner liner,
4. From the outside of the tire carefully probe puncture with awl to determine size, depth and direction
of injury. Use the awl to remove any foreign object
5. Examine tire liner for any other sign of damage.
6. Select patch required and clean punctured area of inner liner with buffing solution. Clean an area
slightly larger than patch. While buffing solution is still moist clean the scrape the area first then wipe with
a clean cloth.
7. Apply thin coat of vulcanizing fluid to buffed surface and in the injury channel. Allow cement to dry.
Most patch applications fail because the vulcanizing fluid is not allowed to dry adequately.
