I just filtered my list of the 7000 most used English words and the only additional words with a stress -ure ending I could find were
endure, lure, obscure, procure, secure.
The more common sound for -ure endings is an unstressed /ur/er/:
adventure, agriculture, architecture, capture, caricature, conjure, creature, culture, departure, expenditure, exposure, failure, feature, figure, fissure, fracture, furniture, future, gesture, injure, lecture, legislature, literature, manufacture, measure, miniature, mixture, nature, picture, pleasure, pressure, procedure, puncture, scripture, signature, structure, temperature, torture, treasure, venture, vulture.
