It depends on how you pronounce "tour." The R influences the OO sound, which sounds like the long OO in too followed by an (ur). Dictionaries show this as a short OO as in good and foot, but it is much closer to a long OO sound. The same sound appears in the words boor, poor (pour), and spoor. Words with a long OO include: U words with a silent E (tune, dude) UE words (due, clue) OU words (ghoul) Words with a YOO sound as in humid, human, mule, cute, feud, and fuel.
