Honda & Acura Center Caps — the 69 mm 44732 Family
If you drive a Honda or Acura from the 2000s or 2010s, there's a strong chance your center caps belong to one big, well-documented family: the 69 mm (2.72 in) OD caps built around the 44732 part-number series. Accord, Civic, CR-V, Odyssey — the family covers a huge share of the Honda fleet, and Acura drinks from the same well.
The Honda side
The reference part is 44732-S9A-A00, and the family is listed across many 2000s–2010s Accord, Civic, CR-V and Odyssey wheels. That breadth is why "Honda center cap" searches return this size so consistently — and why it's a good first hypothesis for a Honda of that era. A hypothesis, though. Honda sold a lot of wheels in twenty years, and trims and special editions wander outside the family.
The Acura side: same family, published ID
Acura caps measure 69 mm OD with a 64 mm clip ID, under part numbers 44732-SY8-A100, 44732-S0K-A000 and 44732-S9A-A00 — note the last one is shared letter-for-letter with the Honda family reference. This is the cleanest illustration on the site of why we keep saying caps follow part numbers, not brand prestige. The Acura number gives you the full fitment in one line: face diameter and clip diameter, both published, both checkable with a caliper in under a minute.
Don't confuse the cap with Honda's bores
Honda hub bores vary by era — a 2006+ Civic sedan centers on 64.1 mm, the HR-V likewise, while a 1992–1995 Civic runs a 56 mm bore. Interesting numbers, none of them cap sizes. The Acura 64 mm clip ID sitting a tenth of a millimetre from the 64.1 mm Civic bore is a coincidence that has surely sold some wrong caps over the years. Bore centers the wheel; clips hold the cap. Different jobs, different numbers.
Where the family ends
One boundary worth respecting: the 44732 family's documented heartland is "many 2000s–2010s" Hondas — not all of them, and not the decades on either side. Earlier Hondas and the newest generations run their own wheel programs, and their caps are their own parts. The era label gets you a hypothesis; the part number draws the actual border. If your cap's back carries a 44732-series number, you're inside the family regardless of what the calendar says. If it doesn't, no model-year argument can put you there — measure the cap you have and work from its own numbers.
