Wheel Bolt Pattern Guide

Your vehicle's bolt pattern is the starting point in determining whether a wheel will fit your car. While there are numerous different bolt patterns today on vehicles, cracking the code is not as complicated as it appears.

If you want to install new aftermarket rims on your vehicle, the lug pattern scheme is crucial wheel fitment information for fitting them.

Wheelsize.com offers free bolt pattern charts to help you find out whether your vehicle is compatible with custom rims.

Within a few clicks, you'll be able to tell what bolt pattern your vehicle requires.

How to Use Wheel Bolt Pattern Charts

Our charts contain bolt pattern data (also known as, bolt circle, stud pattern, lug pattern, pitch circle diameter or simply PCD) and also other wheel sizing data like wheel offset (ET), backspacing, stud thread size, rim size and center bore for all makes, models with the breakdown by years.

We also provide a conversion table that explains how to translate all measurements (bolt patterns, ET, center hole, stud thread size, etc.) are in metric except for some lug nuts or lug bolts, but we explain how to convert to inches regarding the bolt patterns; scroll down and read more.

On top of that, the bolt pattern cross-reference database is at your fingertips to help you find out what cars may theoretically swap the wheels. Our online bolt pattern finder includes a list of lug patterns for different vehicles and identifies other cars with the same PCD.

What is Bolt Pattern?

The bolt pattern is the number and spacing of the lug hole openings, which will match the vehicle hub's corresponding stud or bolt pattern measurement.

A bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns may contain 4-, 5-, 6-, or 8-lug holes or studs. A bolt circle of 4x100 would indicate a 4-lug pattern on a circle with a diameter of 100mm.

The bolt pattern consists of two numbers and looks like this (5x4.50) - the first number in this example, "5", indicates how many bolt holes or studs are on the vehicle. The other number, "4.50", describes the diameter of the circle formed by those "5" holes or studs in either inch or millimeter units (4.50 is inches).

Another example: a bolt pattern of 4x100 indicates a pattern with 4 lugs on a circle with a diameter of 100mm.

How to measure the bolt-pattern

Measuring the bolt pattern isn't difficult for a four-lug wheel since you can gauge via the center from one opening to the other. The 6-bolt and 8-bolt patterns are also measured from the center of two bolt holes that sit directly across.

However, the 5x5 bolt pattern requires an additional step. To measure a 5 lug wheel's bolt pattern, you must measure from the middle of one lug to an imaginary outboard plane that would connect the two opposite lugs.

There are several bolt patterns with diameters very close to each other, so this method may not be accurate. To be sure, consult our bolt pattern guide or pick up a bolt pattern gauge.
