How easy is it to explode a tubeless tire whilst seating, and how do I avoid this? I installed tubeless tires about two months ago, but the back tire had been leaking fluid and yesterday went completely flat. All the fluid inside has dried up and a lot of it had built up between the tire and the rim wall, so I'm guessing I didn't seat it properly first time. I remember I heard a small pop and stopped inflating because I was worried I would blow the tire off the rim. It seems I was being over cautious though so now that I have to redo everything I would like to know how afraid I should be of having the tire explode, how long it should take for an air compressor to seat the tire and when to know that it's time to stop.
The tires I'm using are 700cx35 gravel king tubeless ready tires with a max psi of 60

The pop is what you are waiting for when inflating. It means that the tyre has become seated on the rim and will stop leaking  air fast and it is now enough to just add the air as necessary.
For 35c gravel tubeless tyres I would use pressures about 35-40 PSI or somewhat more if you are heavier than me (many people are). For the initial seating I would go up to 50 get some proper pressure. There is no reason to go to 60 but it won't explode unless the tyre is not connected to the rim properly - but then the explosion would rather be a fast burp of air, the tyre would remain intact.
