Following on from the link above, I have conducted a test deflating my tyres. This appeared to cause the tyre to unseat because there was a poping sound and some sealent leaked out at the rim. The good news from this is that I was able to reflate and presumably reseat my tyre using my frame pump that I have when out cycling. so in the event of a full deflation I should be able to reinflate providing I can seal the puncture. My thinking is on the downside my rims are not the best profile for tubeless (despite being tubeless ready) or they would not unseat in the first place based on the link I posted. Having checked out my rim profile I already suspected this because they do not seem to conform to the best practce listed by Malcolm in the link. Also I have seen some reports on the web of tubeless blowing off Hydra rims. I will still be happy to use at 65psi and and reassured that I can reinflate on a ride.
