What these columns mean

OE fitment: The package fitted at the factory for that trim.
Alternative: A size the car accepts without modification — plus-sizing, winter setups or optional wheels.
Rim size: Rim diameter × width in inches, and the factory offset (ET) in millimetres, e.g. 18x7.5 ET25.
Bolt pattern (PCD): Number of studs and the diameter of the circle they sit on. It must match exactly.
Center bore: Diameter of the hub hole. Larger aftermarket bores need hub-centric rings.
Pressure: Recommended cold inflation pressure for that axle, in psi.
Thread size: Lug bolt or nut thread — needed when buying aftermarket fasteners.
