How to Find Your Wheel’s Bolt Pattern

If you are interested in putting a new set of wheels on your car, one of the first and most important things you should know is the bolt pattern of the wheel that is currently on your vehicle. The bolt pattern refers to the number of lugs on the wheel and the distance between them. You cannot put a wheel on your vehicle that does not match the bolt pattern of your vehicle. Bolt patterns can be measured in inches or millimeters and come in a variety of sizes.

Blackburn’s will know the right bolt pattern for your car and will give you the wheel options available for your vehicle. will automatically display every option available once you enter the make, model, and year of your vehicle. If you are unsure, please feel free to contact us and we will be happy to help. In the event you need to determine the correct bolt pattern for your vehicle, follow the instructions below.

The bolt circle diameter (BCD) is an important part of understanding bolt patterns. To figure out the BCD, lay one of your wheels on the ground and draw a circle that runs through the center of each one of the lug holes. That circle is the “bolt circle”. You will then need to measure the diameter of that circle. You can also figure out your BCD by using a tape measure on the vehicle’s lug studs on the rotor. You will need to run the tape measure from the center of the stud to the center of the stud that lies across the wheel from the first you just measured. On a 4 or 5 bolt wheel, it is the second stud from the one you choose to start with. On a 6 lug wheel, it is the third stud over. Since bolt patterns are measured in inches and millimeters, it is best to use a tape measure that has both units of measurements.

The second part of the bolt pattern is easy. You only need to count your lugs. If you have 5 lugs and a BCD of 4.5″, your bolt pattern is 5×4.5″. If you have 4 lugs and a BCD of 100mm, your bolt pattern is 4x100mm.

New OEM wheels and antique hubcaps can be expensive, so be very careful when measuring your BCD since many bolt patterns are within fractions of an inch or millimeters of each other. Even though the numbers may be close, the wheel still may not fit or will not fit the way you would like it to. If the measurements are off and the lugs are not centered on the wheel, it will cause the wheels to vibrate, and eventually ruin the wheel(s) beyond repair.
