What happens if you try to put a regular tire on a UST wheel without a tube? Will it pop off? Will it leak and need stans? Will it work for a while and then pop off in the middle off an epic all day ride stranding you in the forest?

I know this has probably been covered several times but the search thing sucks and I'm lazy. So just help me out. TIA

pretty sure it won't work. maybe it works with stans conversion, but UST tires have different bead to hold the rim

stans will seal all the pinholes on a non-UST tire and tubeless ready tires. It will also help seal any bead air leaks...

So I mount the regular tire on my UST wheel, put in some stans sealant, inflate and I'm good to go?

Then whats all this conversion stuff about?

I tried it and was disappointed.
I used some standard Hutchison Pythons and then some Panaracer XC Pros with Stans on my Mavic Crossmax UST rims. Left me on the trail. The Python sidewall ripped twice (very thin) and the XC Pros burped air when running close to 30#. I wound up carrying tubes just in case...then thought "what the H**L"...popped for the tubless tires and never looked back.
You may have better luck with different (heavier) tires...but I was trying to save a little spinning weight.

Unfortunately if you're going for saving weight with tubeless, that isn't going to happen unless you run a very small amount of stans.

I've had varying success with stans on ust rims with regular tires (depends on teh tire). You generally have to put in two scoops (60g each if i recall correctly) so if you had a lightweight tube thats 100-120g (standard tubes are 200-240g). No weight savings if you're running a lightweight tube. The reason to run stans is more so for puncture sealing.
