Reading the table

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.
Staggered
A wider tire on the rear axle than the front. Front-to-back rotation is not possible.
Thread size
Lug bolt or nut thread — needed when buying aftermarket fasteners.

Considering a different size?

Run your OE size against the one you want to see diameter change, ground clearance and speedometer error.
