FG131 Forged Alloy Wheel
FG131 is a forged alloy wheel (rim) in 1 finish: Gloss Black Machined Face. It is an OEM-fit replacement, made to the size, bolt pattern, offset and center bore of the original wheel. It comes in 20–21 inch: 4 sizes (20x10, 20x11, 21x10, 21x11), 1 bolt pattern (5x120), offset ET 37–40 mm and center bore 74.1 mm. Not sure what PCD, ET and CB mean? Read how to choose wheels.

What these numbers mean
- Size (D x J)
- Diameter in inches, then rim width in inches: 20x10 is a 20 inch wheel with a 10 inch wide rim. The J after a width, as in 10J, names the rim flange profile.
- Offset (ET)
- The distance in mm from the wheel's centerline to its mounting face. FG131 comes in ET 37–40; 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: 5x120 is 5 bolts on a 120 mm circle. It must match the vehicle.
- Center bore (CB)
- The central hole that sits over the vehicle's hub: 74.1 mm for FG131. A bore larger than the hub needs centering rings.
