What these numbers mean
- Size (D x J)
- Diameter in inches, then rim width in inches: 18x8 is a 18 inch wheel with a 8 inch wide rim. The J after a width, as in 8J, names the rim flange profile.
- Offset (ET)
- The distance in mm from the wheel's centerline to its mounting face. 03031 comes in ET 30; 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: 66.56 mm for 03031. A bore larger than the hub needs centering rings.
