Choosing the right wheels for your car or truck is about more than just style; it’s also about safety and ensuring a perfect fit. One of the most critical measurements when selecting new wheels is the bolt pattern. This guide will break down everything you need to know about bolt patterns, helping you confidently choose the correct wheels for your vehicle.

What is a Bolt Pattern?
A bolt pattern, also referred to as a lug pattern or PCD (Pitch Circle Diameter), is the measurement that describes how the wheel attaches to your vehicle’s hub. It’s defined by two numbers.
The first number indicates the number of lug holes on your wheel. These are the holes through which the lug nuts or bolts are fastened to secure the wheel to your vehicle. Common configurations include 4-lug, 5-lug, 6-lug, and 8-lug patterns. Generally, smaller cars tend to have fewer lugs, while larger trucks and SUVs often have more for increased strength and load capacity. For instance, a compact car like a Kia Rio might use a 4-lug pattern, while a heavy-duty truck like a Ford F-250 will typically have an 8-lug pattern. Five-lug patterns are exceptionally common across a wide range of vehicles.
The second number represents the diameter of the imaginary circle formed by the center of these lug holes. This diameter is usually measured in millimeters (mm). To visualize this, imagine drawing a circle that passes through the center of each lug hole on your wheel. The diameter of this circle is the second number in your bolt pattern measurement.
Therefore, a bolt pattern is expressed as “Number of Lugs x Pitch Circle Diameter”, for example, 5×114.3. This example indicates a 5-lug wheel with a pitch circle diameter of 114.3 millimeters.
Why is Bolt Pattern Important?
Understanding your vehicle’s bolt pattern is absolutely essential for several reasons:
- Safety: Incorrect bolt patterns can prevent the wheel from sitting flush against the hub. This can lead to vibrations, uneven wear on tires and bearings, and critically, wheel detachment while driving, posing a severe safety risk.
- Proper Fitment: Wheels with the wrong bolt pattern simply won’t fit. The lug holes won’t align with the studs on your vehicle’s hub, making installation impossible and rendering the wheels unusable.
- Vehicle Compatibility: Manufacturers design wheels and hubs to work together as a system. Using the correct bolt pattern ensures that the wheel is centered properly on the hub, distributing weight and stress as intended by the vehicle engineers.
In short, knowing your bolt pattern isn’t just about aesthetics; it’s a fundamental requirement for safe and functional wheel installation. Trying to force a wheel with an incorrect bolt pattern is dangerous and should never be attempted.
How to Find Your Vehicle’s Bolt Pattern
Determining your vehicle’s bolt pattern doesn’t have to be a guessing game. Here are a few reliable methods:
-
Consult Your Vehicle’s Manual or Specifications: The most accurate source of information is your vehicle’s owner’s manual or the manufacturer’s specifications. This documentation often lists the bolt pattern under the “wheels” or “tires” section.
-
Use Online Bolt Pattern Guides: Websites like conduct.edu.vn (where this article is hosted!) provide extensive vehicle bolt pattern lookup tools. Simply find your vehicle’s year, make, and model in the lists provided to identify the correct bolt pattern. (See below for a starting list!).
-
Measure Your Existing Wheel: If you’re unsure or want to double-check, you can manually measure your existing wheels.
- Count the Lug Holes: First, count the number of lug holes on one of your wheels. This will be the first number of your bolt pattern.
- Measure the Diameter (PCD):
- For wheels with an odd number of lugs (5-lug, etc.): Measure from the center of one lug hole to the outer edge of a lug hole directly across from it (skipping the center hole).
- For wheels with an even number of lugs (4-lug, 6-lug, 8-lug): Measure from the center of one lug hole to the center of the lug hole directly opposite it, straight across the wheel’s center.
- Use millimeters for the most accurate measurement.
-
Contact a Wheel Fitment Expert: If you’re still uncertain, don’t hesitate to contact professionals. Tire and wheel shops, or online retailers specializing in wheels, have expert fitment teams who can assist you. For example, BB Wheels (as mentioned in the original article) has a team that can help determine your bolt pattern based on your vehicle’s year, make, and model.
Important Note: Always double-check bolt pattern information before purchasing new wheels. If you are ever unsure, it’s best to consult a professional to avoid costly mistakes and ensure your safety.

Frequently Asked Questions: Wheel Bolt Patterns
How do I find out my bolt pattern?
First, count the lug holes on your wheel (4, 5, 6, or 8). Then, measure the diameter of the imaginary circle formed by these holes in millimeters. For 5-lug wheels, measure from the center of one hole to the outer edge of a directly opposite hole. For even-numbered lug wheels, measure center-to-center across opposite holes. Bolt patterns are represented as “Number of Lugs x Diameter,” like 5×114.3.
What are common 5-lug bolt patterns?
While 5-lug patterns are frequent, there’s a wide variety including: 5×98, 5×100, 5×105, 5×108, 5×110, 5×112, 5×114.3, 5×115, 5×120, 5×120.7, 5×127, 5×130, 5×135, 5×139.7, 5×150, 5×160, and 5×205. This variety emphasizes the importance of precise measurement for your vehicle.
What is a bolt pattern in simple terms?
Imagine a circle going through the center of your wheel’s lug nut holes. The bolt pattern tells you two things: how many lug holes are on your wheel and the diameter of that imaginary circle. It’s crucial for wheel fitment and safety.
