Same brand of tubes (Challenge) on two different wheels.

One tube failed at home while the bike was stored (went downstairs to find it was flat), next I think was when inflating but I can't remember, then this third one was out on the road while bombing along on the TT bike (the only bike I use Latex on). This tube only lasted 800km. The rims are super smooth tubeless ready style and I inflate to around 80-85psi. Here's what the latest failure looks like, they've all failed in this same area:



Is this an issue with the batch / brand of tubes perhaps?
Maybe the way I'm installing them?
Or perhaps it's sabotage from Big Tubeless?

Any thoughts? 🤔

That said, the rims and tyres are tubeless ready, so perhaps I'm better off converting them to tubeless instead.
