My rubber queen non ust went straight up too with a track pump on bonty skinny rims, but as previous person said, very porous walls and you could see it bubbling away. Be generous with the stans fluid (1.5 scoops high volume) and a bit of shaking about and you should nail it. They’re more reluctant to “pop” than the rq. Mines held their pressure for over a week now without any loss.
