Wheel repairs that use welding, heating or peening are not approved.
1. Raise and suitably support the vehicle.
2. Remove the tire and wheel assembly.
WARNING: To avoid serious injury, do not stand over the tire when inflating. The bead may break when it snaps over the safety hump. Do
not exceed 275 kPa (40 psi) of air pressure in any tire if the beads are not seated. If 275 kPa (40 psi) of air pressure will not seat the beads,
deflate the fire. Relubricate the beads. Reinflate the tire. Overinflation may cause the bead to break and cause serious injury.
3. Locate leaking areas by inflating the tire to 345 kPa (50 psi) and dipping the tire and wheel assembly into a water bath.
4. Mark the leak areas and remove the tire from the wheel.
5. Scuff the inside wheel surface at the leak area with 80-grit sandpaper. Clean the leak area with a general purpose cleaner.
6. Apply a 3.3 mm (0.13 inch) thick layer of adhesive/sealant to the leak area. Allow it to dry for 12 hours.
7. Install the tire on the wheel. Inflate the tire to 345 kPa (50 psi) and check for leaks as in step 3.
