- Cut Off Excess Plug Length
Align face flat with the tyre exterior tread using sharp knife once adhesive cured – prevents dislodging
- Inflate Tyre & Observe
Reattach valve cap and use compressor to reinstate pressure. Closely inspect for 5 minutes ensuring no leaks evident around sealed hole or sidewalls as glue expands fully.
