Look up OE bolt pattern, tire size, offset, and center bore by year, make, and model — then check if an aftermarket wheel and tire setup fits. No VIN.

Pick year, make, and model to pull factory wheel specs: lug pattern (PCD), center bore, fastener type, torque, and the OE tire and rim configurations, including staggered front/rear setups. That is the baseline you need before you order aftermarket wheels instead of guessing from a forum post.
Enter a candidate tire size, bolt pattern, rim width, offset, and center bore. The guide compares them to OE: PCD match, hub-centric ring if the wheel bore is larger, offset within about ±5 mm, ETRTO rim width for the tire, and diameter within ±1% (or ±3% as acceptable). You get Compatible, Compatible with mods, or Not compatible — not a vague “should fit.”
When the wheel center bore is larger than the hub, the result includes the ring OD×ID to order. Offset is shown as millimetres from OE so you can see poke versus tuck. Diameter percent flags a speedometer-relevant height change even when the bolt pattern already matches.
You do not upload photos or a VIN. Year/make/model is used only to fetch OE specs. The aftermarket comparison (pattern, bore, offset, rim width, diameter) runs locally in the tab. There is no saved vehicle garage and no signup required to check a fit.
Use the catalog dropdowns. Specs load for that vehicle — bolt pattern, center bore, fasteners, and OE tire/rim rows, including front and rear when the car is staggered.
Note PCD, hub bore, ET, rim width, and OE tire size. Those numbers are the reference for the aftermarket checker, not a tire shop’s guess.
Fill bolt pattern (for example 5x114.3), rim width, offset in mm, center bore, and a tire size code. You do not upload a parts invoice.
Check pattern, hub ring, offset window, rim width, and diameter band. “Compatible with mods” usually means a hub ring or a small ET/diameter compromise — not a guaranteed fender clearance.
