  Important Installation Notes (TPU Specific)

  • Do NOT inflate the tube heavily before installing into the tire.

  • Before installation, slightly inflate (≤5 PSI / 0.35 BAR) to check for air leaks.

  • During installation, ensure the tube is evenly seated against the tire inner wall before full inflation.

  • Never inflate the tube alone over 6 PSI, otherwise permanent damage may occur.
