The three ways to find your bolt pattern without guessing

Your wheel bolt pattern is the number and spacing of the holes that connect your wheel to the hub. You need this measurement to buy replacement wheels, adapters, or lug nuts that actually fit. The pattern is written as two numbers — like 5x114.3 — where the first number is how many bolts hold the wheel, and the second is the diameter of the circle they form, measured in millimeters.

You can find this information three ways: check your vehicle's owner manual or door jamb label, measure the bolt holes yourself, or contact your vehicle's manufacturer or a tire shop with your vehicle identification number (VIN). The manual is fastest. Measuring takes about ten minutes and requires only a ruler or caliper. Calling is the backup when you cannot locate printed documentation.

Key Takeaways

  • Your owner manual lists the bolt pattern on a specifications page, usually near the tire and wheel information.
  • The driver's side door jamb often has a sticker showing tire size, load rating, and bolt pattern for your specific vehicle.
  • You can measure the bolt pattern yourself by counting the bolts and measuring the distance across the circle they form, using either a ruler or a caliper.
  • Tire shops and dealerships can look up your bolt pattern in seconds using your VIN, at no cost.

Checking your owner manual or door jamb sticker

The fastest source is your vehicle's owner manual. Open it to the specifications or maintenance section — usually near the front or back — and look for a page labeled "Wheels and Tires" or "Technical Specifications." The bolt pattern appears as a number like 5x120 or 4x100. Write it down exactly as printed.

If you do not have the manual, check the driver's side door jamb. Open the door fully and look at the frame where the door closes. A white or yellow sticker is usually glued there. This sticker shows tire size, load limits, and sometimes the bolt pattern. Not all vehicles print the bolt pattern on the jamb sticker — some only list it in the manual — so if it is not there, move to the next method.

Measuring the bolt pattern yourself

Measuring takes a ruler, caliper, or even a tape measure. First, count the bolts or studs on one wheel. This is the first number in your pattern. Most vehicles have 4, 5, or 6 bolts.

Next, measure the distance across the circle the bolts form. For an even number of bolts (4 or 6), measure from the center of one bolt, straight across, to the center of the bolt directly opposite. For an odd number of bolts (5), measure from the center of one bolt to the center of the bolt two positions away, then multiply that measurement by 1.051 to get the true diameter. This math accounts for the angle between bolts on a five-bolt wheel.

Write down both numbers. If you measured 5 bolts and got 114.3 millimeters, your pattern is 5x114.3. If you measured 4 bolts and got 100 millimeters, your pattern is 4x100. Bolt patterns are always in millimeters, so if your ruler shows inches, convert by multiplying by 25.4.

Using your VIN to look it up

Your vehicle identification number is a 17-character code stamped on the dashboard (visible through the windshield on the driver's side) or printed on your insurance card and registration. Any tire shop, dealership, or wheel retailer can enter this VIN into their system and pull up your exact bolt pattern in under a minute, usually at no charge.

Call ahead or visit in person. Have your VIN ready. The shop will confirm your bolt pattern and can also tell you the offset and width of your original wheels if you need that information for replacement shopping. This method is useful if you distrust your own measurement or if the manual is missing.

Understanding what the numbers mean

A bolt pattern like 5x114.3 breaks down this way: the 5 is the number of bolts, and 114.3 is the diameter in millimeters of the circle those bolts sit on. This circle is called the bolt circle diameter or pitch circle diameter (PCD).

Common patterns for passenger vehicles include 4x100 (many Honda and Toyota models), 5x114.3 (many American and Japanese sedans), 5x120 (BMW and some Audi models), and 5x112 (Mercedes and Volkswagen). Trucks often use 6x139.7 or 6x135. The pattern must match exactly — a wheel for 5x114.3 will not fit a vehicle with 5x120, even though both have five bolts.

What to do if you get conflicting information

If your manual lists one pattern and your measurement shows another, remeasure carefully. Bolt patterns are precise, and a mistake of even a few millimeters means the wheel will not fit safely. Measure at least twice, ideally with two different tools.

If you still see a difference, contact the dealership with your VIN. Dealerships have access to the exact specifications for your vehicle's production year and trim level, which can vary even within the same model year. They can confirm whether your vehicle is an exception or whether your measurement needs adjustment.

Common mistakes when measuring

The most common error is measuring from the outside edge of one bolt hole to the outside edge of another, rather than from center to center. This gives you a number that is too large. Always measure from the middle of the bolt hole to the middle of the opposite bolt hole.

Another mistake is forgetting to convert inches to millimeters if your ruler shows inches. Bolt patterns are always given in millimeters. If your ruler shows 4.5 inches, multiply by 25.4 to get 114.3 millimeters.

A third error is misidentifying which bolts form the pattern. On some wheels, you may see extra holes or studs that are not part of the main bolt circle. Count only the bolts that actually hold the wheel to the hub, not any decorative or secondary holes.

Frequently Asked Questions

Can I use a bolt pattern from a different vehicle that looks the same?

No. Bolt patterns must match exactly. Two vehicles may look similar but have different patterns — for example, 5x114.3 versus 5x120. Using the wrong pattern can cause the wheel to sit unevenly, damage the hub, or fail while driving. Always confirm your own vehicle's pattern.

What if my vehicle has lug nuts instead of bolts?

Lug nuts thread onto studs, which are bolts permanently attached to the hub. The bolt pattern is still measured the same way — count the studs and measure the circle they form. The measurement does not change whether your vehicle uses bolts or studs.

Do I need to know the bolt pattern to rotate my tires?

No. Tire rotation uses your existing wheels, so you do not need the bolt pattern. You only need it when buying new wheels, adapters, or replacement lug nuts that must fit your hub.

Can the bolt pattern change if I buy aftermarket wheels?

No. Your vehicle's hub has a fixed bolt pattern that does not change. Aftermarket wheels must match your hub's pattern. Some aftermarket wheels come with adapters that allow a different pattern to fit, but the adapter changes the effective pattern and offset, which affects handling and safety. Use adapters only if recommended by a professional.

What is the difference between bolt pattern and offset?

Bolt pattern is where the bolts are located on the wheel. Offset is how far the wheel's mounting surface sits from the centerline of the wheel itself. Both matter for fit, but they are separate measurements. Your manual or a tire shop can provide both.
