ha-i-ru, three beats — the "ha" and "i" are separate, so it's never the English word "hire."

部屋に入ってもいいですか uses the te-form 入って, which adds a geminate: ha-i-t-te, four morae with a silent held beat before the t releases. Contrasting that with the plain three-beat 入る shows how the small っ inserts pure time rather than changing any sound's identity.
The reflex is to say "HI-roo" — the a and i fused into the vowel of "high," a stressed first syllable, and a rounded English-r ending. That collapse costs a whole mora. Separate the two vowels into distinct pulses, tap once for the r, and keep the lips flat throughout the final u.
