2009 BMW X3 bolt pattern

The

lug pattern

of a 2009 BMW X3 is 5x4.72. Let’s discuss exactly what this means in case you aren’t brushed up on your automobile wheel jargon. Bolt patterns, also called lug patterns, are generally expressed in the following way:

# of bolts x diameter of the circle they form

As we see with this X3, the bolt pattern is 5x4.72, which means each wheel has five bolts and they form a circle 4.72 inches in diameter.

It’s good to know some other wheel specifications if you are looking for a complete overhaul. The wheels’ stud size, wheel offset, center bore measurement, and torque specifications should be plenty of information to complete any job:

Factory wheel size: 17”

Stud size: M14 x 1.5

Offset: 32-40 mm

Center bore: 72.6 mm

Wheel tightening torque: 140 Nm

How to measure your BMW X3’s bolt pattern

If you want to check the measurement for yourself, you can do so with a tape measure or standard ruler.

Choose one of the bolts and measure from the outer edge of it to the center of the bolt opposite it. Since X3s have an odd number of lugs, your measurement will wind up in the middle of two bolts if you measure straight across. Adjust by picking one of the nearest lugs and measuring to its center.

After you measured your diameter, just put it together with the number of bolts on each wheel and you’ve got your bolt pattern!
