Tire Repair: Notes

WARNING: This page is about a different car, the 2020 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
  • Tire changing can be dangerous and should be done by trained professionals using proper tools and procedures. Always read and understand any manufacturer's warnings contained in their customers literature or molded into the tire sidewall.
  • Serious eye and ear injury may result from not wearing adequate eye and ear protection while repairing tires.
  • NEVER inflate beyond 275 kPa (40 pounds) pressure to seat beads.
  • NEVER stand, lean or reach over the assembly during inflation.
WARNING:

To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, relubricate the beads and reinflate. Over inflation may cause the bead to break and cause serious personal injury.

WARNING:

Approved safety glasses and gloves should be worn when performing this procedure to reduce the chance of personal injury.

WARNING:

Wear gloves when inspecting the tires in order to prevent personal injury from steel belts sticking through the tire.

NOTE:
  • For Run Flat Tire Repairs, refer to the manufacturer's recommended repair procedure.
  • NEVER repair tires worn to the tread indicators 1.6 mm (2/32 in) remaining depth.
  • NEVER repair tires with a tread puncture larger than 6 mm (0.25 in).
  • NEVER substitute an inner tube for a permissible or non-permissible repair.
  • NEVER perform an outside-in tire repair (plug only, on the wheel).
  • Every tire must be removed from the wheel for proper inspection and repair.
  • Regardless of the type of repair used, the repair must seal the inner liner and fill the injury.
  • Consult with repair material supplier/manufacturer for repair unit application procedures and repair tools/repair material recommendations.

Three basic steps for tire puncture repair:

  1. Remove the tire from the wheel for inspection and repair.
  2. Fill the injury (puncture) to keep moisture out.
  3. Seal the inner liner with a repair unit to prevent air loss.
