My problem right now is with DT Swiss R460 rims set up tubeless. I do have a set of Mavic Cosmic disc UST wheels which are going on my new disc bike but I have not ridden them yet. They appear to be a great fit with the included Mavic Yskion tubeless tires provided. The fact that these tires can hold air for some time without any sealant at all is a good sign that this is a well designed system. I will not speculate any more about future air-tightness due to not having ridden them yet.
