The 2003 Honda Civic’s bolt pattern, also referred to as a lug pattern, is 4x100 millimeters or 4x3.9 inches. Here’s what these numbers represent:

To phrase this another way, each of your 2003 Honda Civic’s wheels has four bolts arranged in a circle with a diameter of 100 millimeters, or about 3.9 inches.

Knowing your bolt pattern is certainly important when you’re looking for new rims, but you’ll need to know some additional wheel specifications to find a set that’s the right fit. These are some other common wheel specs on a 2003 Honda Civic:

Factory wheel size: 14” to 15”

Stud size: M12 x 1.5

Offset: 34 to 38 mm

Center bore: 56.1 mm

Of course, even within the same make and model year, some measurements can vary based on different factors, so you’ll want to confirm these ones match your own 2003 Honda Civic. While you’re shopping, most tire and wheel shops will also have tools that will allow you to check whether a certain set of wheels or rims are compatible with your vehicle.

How to measure your Honda Civic’s bolt pattern

If you want to confirm your 2003 Honda Civic’s bolt pattern for yourself, it’s quick and easy to do so—and all you need is some measuring tape.

Once you have that on hand, pick any bolt hole on any wheel. The number of bolts on your wheels can affect how you need to take your measurement, but since the Civic only has four, it’s pretty straightforward. Simply measure from the center of this bolt hole to the one directly across from it and note the measurement. This is the diameter of your circle.

Place that measurement after your number of bolts (four), and there you have it: your 2003 Honda Civic bolt pattern!
