The ''bolt pattern'' determines the number and position of the bolt holes on the wheel to line up with your vehicle's studs on the mounting hubs. The bolt holes are spaced evenly about the [[wikt:bolt circle#Noun|bolt hole circle]]. ''Wheel studs'' are the bolts that are on your mounting hub and are used along with lug nuts to attach the wheel to the car. The ''bolt hole circle'' is the circle that the center of each bolt aligns with. The second number in a bolt pattern is the diameter of this circle.<ref>{{cite web|title=Wheel Tech: Bolt Pattern|work=tirerack.com|url=https://www.tirerack.com/wheels/tech/techpage.jsp?techid=92}}</ref> The bolt circle has the same center point as the mounting hub to ensure that the wheel will be [[concentric]] with the mounting hub. The bolt circle's measurement is called the bolt circle [[diameter]] (BCD),<ref>{{cite web|title=Bolt Circle Diameter (B.C.D.)|work=Sheldon Brown's Bicycle Glossary|url=http://www.sheldonbrown.com/gloss_bo-z.html#bcd|access-date=3 Dec 2010}}</ref> also called the ''pitch circle diameter'' (PCD).<ref>{{cite web|title=P.C.D.|work=Sheldon Brown's Bicycle Glossary|url=http://www.sheldonbrown.com/gloss_p.html#pcd|access-date=3 Dec 2010}}</ref>

The bolt circle diameter is typically expressed in ''mm'' and accompanies the number of bolts in your vehicle's bolt pattern. One example of a common bolt pattern is 5x100&nbsp;mm. This means there are 5 bolts evenly spaced about a 100&nbsp;mm bolt circle.

The picture to the right is an example of a [https://sizemywheels.com/lz-pcd/5-100 5×100&nbsp;mm bolt pattern] on a Subaru BRZ. The wheel has 5 lug nuts and utilizes a 100&nbsp;mm bolt circle diameter.

Some of the most common BCD values are 100&nbsp;mm (≈3.94&nbsp;inches), 112&nbsp;mm (≈4.41&nbsp;inches), and 114.3&nbsp;mm (4.5&nbsp;inches).{{citation needed|date=September 2020}} Always check your owner's manual or call your local car dealership to confirm the bolt pattern on your vehicle. Over the years, over 30 different bolt patterns have been used by car manufacturers,<ref name="boltsirkel.no">[http://www.boltsirkel.no/ Boltsirkel.no]</ref> with most of the different bolt patterns being incompatible with each other.{{citation needed|date=September 2020}}
