UST tyres can actually seat worse on stans rims…the burping happens because the thinner tyres have less sidewall support so tend to roll more when being aggresive.
I find the best option is something like a maxxis EXO. Its around 850g and has a thicker sidewall (more like 1.5ply)so it supports being run tubeless better. I still run lighter tyres, but you gotta keep the pressures up (25-30psi) to stop them squirming too much. See, I understand that lots of people don’t like UST exactly because they have extra material in the sidewalls in comparison to the same model as a non-UST
IMO/E The main difference in UST, though, is the bead which has a lot more rubber at the point of contact between tyre & rim and so shouldn’t (doesn’t IME) move so easily when the carcass is pulled about under cornering
