Will it fit? We already know.
Used doesn't mean uncertain. Every listing on the Exchange runs through the same fitment engine that powers Fitment Industries and Custom Offsets — the one sitting on 180K+ real, photographed builds.
Tell us once, shop everything.
Prefer plates? The homepage finder takes license plate and VIN too. Your vehicle follows you across every page — and saves to My Garage, the same garage you use on FI and CO.
How used gear gets fit-verified.
Catalog spec-check
Sellers pick the exact part from our catalog, so bolt pattern, offset, bore, and size prefill from factory data — then a spec-check verifies photos match before the listing goes live.
Fitment engine match
With your vehicle set, search only shows what the engine says works — the identical question our retail sites ask, answered from the same data. "✓ Fits your car" chips on every card.
Gallery-verified
The badge nobody else can copy: Verified on your exact chassis — this part, photographed on a real build of your car in the Fitment Gallery.
The specs, decoded.
| Spec | What it means | Why it matters used |
|---|---|---|
| Offset (ET) | Distance from the wheel's mounting face to its centerline, in mm | Decides poke vs. tuck — and whether you'll rub. Non-negotiable number on every wheel listing. |
| Bolt pattern | Lug count × circle diameter (e.g. 5×114.3) | Wrong pattern = doesn't bolt on. Prefilled from catalog so it can't be fat-fingered. |
| Center bore | The hub hole diameter, in mm | Used wheels often come with hub rings — listings say if they're included. |
| Width & diameter | e.g. 18×9.5 — sizes in inches | Drives tire choice and clearance. Sets list all four corners for staggered fitments. |
| DOT date | Tire manufacture week/year, stamped on the sidewall | Required on every set listing — the Exchange caps tire age in the rules. |
Do the math yourself.
Offset comparisons, tire size changes, bolt-pattern lookups — the full family toolbox.
