Last year hade a sad back.
Ran into a taper that distorted my frond tire.
A tire that was 30km old.

Normally I would have changed that tire, but because it was that new wanted to repair it.

Wanted to repair it with one off these

Removed the tire at work

Grind some internal rubber away, to smooth it out

Glued the service

Mounted the plug, pressured it, and mounted the tire back.
Until now, she holds it quit good
