The Cap Finder
Two ways to your size. Know your vehicle? Pick it and get the sourced OEM cap size and part numbers. Already holding a caliper? Enter your measurements and match them against real fitments. Either way, finish with the 60-second measure check — the wheel, not the badge, decides the cap.
The Cap Finder app by OEMCenterCaps.com — JTT Imports, Canada. Install it:
1 — Find by vehicle
Sizes shown are the commonly listed OEM fitments from the sources cited in our research notes — a starting point that the measure check confirms. Brands marked “measure first” have no sourced cap spec we are willing to print, so we teach the measurement instead of inventing a number.
2 — Measure & match calculator
New to measuring? The How to Measure page walks the caliper steps. No cap to measure because it's lost? Measure the wheel's center-bore opening directly and use that as your clip diameter.
Why a tool, not just a chart?
Charts flatten the truth: the same Honda badge wears a 69 mm cap on one wheel and something else on another; a Tesla's published sizes openly disagree with each other. The Cap Finder keeps those conflicts visible instead of hiding them, and it always lands you back on the one step that never lies — measuring your own cap or wheel. Spend the minute here, save the return shipping.
