When you say you're going to use UST tyres with Stans No Tubes what do you mean exactly as you might be at cross purposes?
A Stans No Tubes kit will allow you to convert a normal tyre and rim to tubeless so you don't need a UST tyre.
Specific UST tyres, (except Michelin who have developed a universal design), only work properly on UST rims as they have bead locks incorporated into the rim design. If you use a UST tyre on a UST rim it's Def worth putting latex in too such as Stans No Tubes latex to stop thorn punctures etc.
You can also use normal tyres on a UST rim with latex, they will seal with about 30% more latex added than normally recommended.
I don't know anyone who has tried mounting a UST tyre on a normal rim with a No Tubes kit

Would be more expensive than the normal way too as UST tyres cost more.
