Most of that tyre damage was done riding it flat the 30k into the next town after Tom tried the Finnyleak and that failed, and as Steve B said there goes the old story of tyres coming off the rim if you go tubeless and have a sudden deflation. Tom was crabbing sideways up the road on a dead flat tyre for maybe an hour at mostly 60kph,bet it felt longer and the tyre stayed well on the rim, it looked bloody horrible from my position behind him. Its a bit academic, even tubeless plugs probably wouldn't have helped considering the size of the bolt that caused it.
