What these numbers mean

Size (D x J)
Diameter in inches, then rim width in inches: 20x9 is a 20 inch wheel with a 9 inch wide rim. The J after a width, as in 9J, names the rim flange profile.
Offset (ET)
The distance in mm from the wheel's centerline to its mounting face. C1623 comes in ET 19–65; a lower ET sits the wheel further out.
Bolt pattern (PCD)
The number of bolts and the diameter in mm of the circle they sit on: 5x112 is 5 bolts on a 112 mm circle. It must match the vehicle.
Center bore (CB)
The central hole that sits over the vehicle's hub: 66.5–71.6 mm for C1623. A bore larger than the hub needs centering rings.
