Hi
I'm using the Supersonic version tubeless with a Joe's conversion. Not had any problems with punctures or burping until last week when I lost pressure out on the trail. It was coming out between the tyre and the rim. The reason was because I hadn't topped up the sealant since fitting them nearly a year ago, your meant to top it up every 3 months or so.
To seat them I used a CO2 inflater. It took a couple of days of topping up the air with a track pump and shaking the sealant around the tyre before they sealed properly. Initially there was jizz coming out tiny holes all over the tyre, probably because of the silly thin supersonic carcass.
Hope I've been of some help.
Keith.
