Tire - Front - LH (Repair)
Correction Code 34023008
Warning
Always read and understand
the tire equipment operator’s manual and on-screen instructions before operating the wheel
balancer or tire changer.
Warning
Always make sure to
properly secure the wheel and exercise caution around all moving parts and pinch points,
including the indent rollers. Additionally, secure all loose items such as hair, jewelry,
and clothing, so that they will not catch on moving parts.
Warning
Wear appropriate personal
protective equipment (PPE) including cut-resistant gloves and safety glasses when performing
this procedure.
Warning
The machine must be
operated by no more than one person at a time. Other persons must maintain a safe distance
of at least three feet from equipment while in use.
Warning
Never use equipment that
is defective or not working as expected based on the equipment operator’s manual.
Note
These instructions are based on the
Hunter GSP9700 wheel balancer. Some steps might be different for other wheel balancers.
Refer to the operator's manual and on-screen instructions for specific information.
Warning
Only use cleaning agents and solvents
in a well-ventilated area.

-
Visually inspect the tire. If any of the following are noted, discontinue this
procedure and replace the tire:
- The puncture is on the
shoulder or sidewall
1 Non-repairable areas 2 Repairable area - The foreign object entered the tire at an angle of more than 15 degrees from perpendicular to the tread surface
- The foreign object is more than 1/4 in (6.3 mm) in diameter
- The tread depth is less than 2/32 in (1.6 mm)
- There is oxidation or weather cracking on the sidewall that is deeper than 2/32 in (1.6 mm)
- The tire is more than 10 years old
- The puncture is on the
shoulder or sidewall
- Dismount the tire from the wheel (refer to procedure).
- Place the tire on the tire spreader, with the puncture facing down.
- Spread the sidewalls to create a larger working area.
-
Visually inspect the entire inside of the tire. If any of the following are
noted, discontinue this procedure and replace the tire:
- Evidence of the tire being driven while flat (inner sidewall cracking, separated, or blue in color)
- A previous repair is close enough to the new puncture that the repair areas will overlap
- Previous improper repairs
- Broken, kinked, or damaged beads
- Any other internal damage
- The foreign object is more than 1/4 in (6.3 mm) in diameter
- If the vehicle was outdoors in temperatures below 50 degrees F (10 degrees C), use a heat gun or other heat source to thoroughly warm the tire.
-
Use the paint stick to mark the area around the puncture on the inside and
outside of the tire.
-
Confirm the path of the foreign object (the puncture channel). The puncture
channel must be no more than 15 degrees from perpendicular to the tread surface.
If the puncture channel is more than 15 degrees, discontinue this procedure and
replace the tire.
- Remove the foreign object from the tire.
-
If the tire has an interior foam noise absorber:
-
Use the carbide cutter to clear the puncture channel.
WarningUse a low speed (under 1200 RPM) only. Excessive speed damages the rubber surrounding the puncture channel, increasing the chances of future leakage.
-
Hold the Minicombi insert over the puncture channel. Use the paint stick to
draw an outline that is approximately 15 mm larger than the diameter of the
Minicombi insert.
- Remove the Minicombi insert.
- Apply pre-buff cleaner to the outlined area. Wait at least 5 seconds before continuing to the next step.
-
Use the inner liner scraper to scrape the outlined area.
- Repeat the previous 2 steps until the outlined area is fully cleaned.
-
Use the buffer to lightly buff the outlined area until it is smooth.
CAUTIONDo not remove too much rubber. If the cords are exposed, the tire must be replaced.
-
Vacuum the debris from the inside of the tire.
WarningTo avoid contamination, do not let the vacuum nozzle touch the buffed area. Contamination prevents the Minicombi insert from adhering properly, which can result in tire failure, leading to serious injury or death.WarningDo not use compressed air to clean the buffed area. Compressed air contains moisture and oil that prevent the Minicombi insert from adhering properly, which can result in tire failure, leading to serious injury or death.
- Apply a thin, even layer of blue cement to the outlined area.
-
Allow the cement to dry for at least 5 minutes, then test it by touching with a
clean finger or knuckle. The cement is dry if it feels tacky. Wait until the
cement dries before continuing to the next step.
WarningAllow the cement to dry naturally. Do not use compressed air, a fan, a heat gun, or other artificial means to force the cement to dry faster. Doing so prevents the Minicombi insert from adhering properly, which can result in tire failure, leading to serious injury or death.Tip: The cement dries faster if the tire is rotated so that the repair area is at the highest point of the tire.
-
Rotate the tire so that the repair area is in a comfortable working location.
Ensure that the sidewalls are not spread.
WarningThe tire must be relaxed (sidewalls not spread) before continuing. If the sidewalls are spread, the Minicombi insert does not adhere properly, which can result in tire failure, leading to serious injury or death.
- Apply a small amount of blue cement to the puncture channel.
-
Remove the Minicombi insert from the protective cover.
-
Install the Minicombi insert:
-
Roll the stitcher over the base of the Minicombi insert to fully adhere it to
the tire. Start from the center of the base and roll toward the outside. Ensure
that the whole base is thoroughly adhered to the tire.
- Remove the protective cover from the base of the Minicombi insert.
-
Apply a generous amount of repair sealant to the base of the Minicombi insert
and the buffed area.
NoteDo not attempt to reattach the section of foam noise absorber that was removed earlier (if applicable).
- Mount the tire on the wheel (refer to procedure). Check for leakage.
- Cut off the exposed stem of the Minicombi insert so that the stem is flush with the tire tread.
- Rebalance the tire (refer to procedure).
