Tubeless Tyres -"saying the same things about tubeless tyres over and over again" Hippy read the first f**king post

Horrible sidewall cut thanks to a sharp metal pipe hidden in a puddle on the trail, both tires at the same time, not worth bodging on the side of the trail, ride over.

Tires (Vittoria Terreno Mix 33c) were quite new, so I decided to try and repair them.

• Cleaned the tear area and lightly rubbed the inside with sandpaper
  
• Sewed up the two ends with nylon thread, including just beyond the ends of the cuts to ensure the tear won't spread under stress.
  
• Welded the ends together with rubberized loctite, which also strengthened the sewing
  
• Applied glue and patch on the inside
  
• Installed the tires dry, both seated normally and held air properly with only some hissing coming from the damaged area, but no visible opening nor bulging at 80psi.
  
• Deflated and added some sealant, holes all sealed up, hissing stopped
  
• Lost 20psi in 2 days, went for a ride, nothing exploded.
  
  

It was a bit of a pain to do (2h for both tires) and probably more of a proof of concept than else. Thought of sharing for reference
