The /ɔ/ vowel is usually spelled <or>, <our>, and <oar>, but we also see <au> in laud, <aw> in raw and <ar> after <w> in war. The /ɪə/ diphthong is spelled <eer> or <ear> and unusually <ie> in tier and <ei> in weird. Note that the pair eyesore/icier which the computer pulled out is not a true minimal pair since, as so often the case, /ɪə/ in that word is two syllables rather than the diphthong.
This is a contrast between a long vowel and a diphthong. The starting positions are a long way apart there is no risk of confusion.
Interesting pairs include:
indoor endear
orally eerily
