Tire Repair
Tread punctures or penetrations left unrepaired may cause irreversible tire damage. An improper repair can damage the tire and will void the warranty.

Repair Procedures
Combination patch/stem repair. Steel cord damage must be repaired immediately to prevent rusting of the steel. Using plugs or patches alone on any type of tire is not a safe repair.

Do not perform this part of the repair on a spreader as this deforms the area to be repaired.
1. Remove all foreign matter from the hole. Be careful not to enlarge the hole.
2. Select the proper size reamer. The reamer selection must completely cover the injured area.
3. Select the proper size patch and plug to correspond to the reamer. Center the patch over the puncture and mark 1" beyond the edge of the patch with a crayon.
4. Clean the punctured area thoroughly with a pre-buff chemical cleaner. (do not use gasoline).
5. With the tire in a relaxed position and following the tool manufacturer's recommendation, use a proper hand reamer, carbide cutter, or drill bit to clean the injury.
6. Buff thoroughly to a flat, smooth velvet surface, per RMA. "Be careful not to gouge liner or expose casing liner. Remove buffing dust with a vacuum cleaner. Note: chemical cleaning is not a substitute for mechanical buffing."
7. Apply a cement recommended by the patch manufacturer according to the label directions. Cement must be allowed to dry thoroughly.
8. Lubricate the hole and taper of plug with cement. Insert the plug into the hole, pulling it firmly through so the patch seats to the buffed innerliner. Be sure the bead markings are in the correct position.
9. Stitch from the center out being careful not to trap any air.
10. Cut off the stem 1/16" above the outer surface.

WARNING: Failure to follow the above recommendations could result in sudden tire failure, property damage, personal injury or death.

Repair of Speed Rated Tires
Tires that are speed rated may be repaired with the following procedures; however, these tires would no longer maintain their speed rating.

Determining if the Tire is Repairable - Limits
Never repair a tire worn below 2/32"(.16cm)
Never repair tires with tread punctures larger than 1/4"(.635cm)
Never use an inner tube as a substitute for proper repair.
All repairs must be made from the inside of the tire as well as outside.
The maximum number of nail holes is limited to two per tire and these must be separated by at least 15"(38cm).
No more than one cord per radial ply can be damaged.
Section repairs are not allowed.

Inspection Procedure of a Service Professional
Mark injury and remove the puncturing object.
Before deflating, immerse the entire tire in water to determine if there is more than one hole.
Remove tire from wheel.
Inspect puncture with blunt awl to determine size and type of injury.
Place the tire on a spreader and inspect thoroughly.

If any of the following conditions exists, the tire cannot be repaired:
Holes larger than 1/4"(.635cm)
Run flat damage
Broken or deformed bead wires
Ruptures of radial plies
Deterioration of rubber
Damage to the bead

Valves
New valve stem, core and cap are recommended for all new tubeless tires.

Lubricant
Tire beads and rim flanges should be treated with a recommended lubricant inside and out. Beads should be lubricated both during mounting and dismounting (in case you wish to remount the tire and also to protect the wheel from damage).

Do not, under any circumstances, use liquids such as oil, gasoline, spirits, or water.
