Americans pronounce expired as ihk-SPAHY-urd (/ɪkˈspaɪərd/). Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "The repairman said the appliance warranty expired last month" or "The statute of limitations has expired for this particular offense" — more examples below.
Record yourself saying "expired" and play it back. The mic stays on your device — nothing's uploaded.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "expired", the "d" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
Stress falls on the second syllable, not the others. Stretch SPAHY — keep everything else short and quick.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
