Unlocking the secrets of your go-kart’s hub bolt pattern can feel like cracking a complex code, but fear not, it’s a surprisingly straightforward process with a few key techniques. Knowing this crucial piece of information is essential for selecting the right wheels and ensuring a safe and exhilarating ride. Imagine the frustration of purchasing shiny new wheels only to discover they won’t fit your kart! Furthermore, an incorrect bolt pattern can lead to dangerous wheel wobble or even detachment, jeopardizing your safety on the track. Therefore, accurately determining your go-kart’s hub bolt pattern is paramount for both performance and peace of mind. This guide will walk you through three reliable methods, from simple visual inspections to utilizing precise measuring tools, empowering you to confidently identify the correct pattern and keep your kart rolling smoothly.
Firstly, one of the simplest methods involves a direct visual inspection, particularly if your kart’s hubs are relatively clean and accessible. Begin by carefully cleaning the hub surface to remove any dirt or debris that might obscure the bolt holes. Subsequently, count the number of bolt holes present. Common go-kart bolt patterns include 4 and 5-bolt configurations. Once you’ve determined the bolt hole count, the next step is to measure the bolt circle diameter (BCD). For 4-bolt hubs, simply measure the distance from the center of one bolt hole to the center of the diagonally opposite bolt hole. However, for 5-bolt hubs, the process is slightly more complex. You’ll need to measure the distance between the center of any two adjacent bolt holes and then multiply that measurement by 1.701 to obtain the BCD. Alternatively, you can use a dedicated bolt pattern gauge, a handy tool readily available online or at automotive stores, which significantly simplifies this process, offering a quick and accurate reading.
Secondly, if the hub is significantly corroded or the bolt holes are obscured, you may need to employ a more involved method. In these cases, you can create a template using a piece of cardboard or heavy paper. Place the material against the hub, ensuring it covers all the bolt holes. Then, using a pencil or marker, carefully trace the outline of each bolt hole onto the paper. Next, remove the template and accurately measure the distances between the centers of the traced circles, following the same procedure described earlier for 4 and 5-bolt patterns. This method, while slightly more time-consuming, allows you to obtain accurate measurements even when direct access to the hub is limited. Additionally, consider consulting your go-kart’s owner’s manual or contacting the manufacturer directly. Often, the hub bolt pattern information is included in the documentation or readily available from the manufacturer’s support team. This can save you considerable time and effort, particularly if your kart is a less common model or the hub is difficult to access.
Identifying Your Go Kart Hub
Alright, so you need to figure out your go-kart’s hub bolt pattern. This is a crucial step for getting the right wheels and tires fitted, and thankfully, it’s usually not too difficult. There are a few different ways to go about this, each with its own pros and cons. Let’s break them down so you can choose the method that works best for your situation.
Direct Measurement: The Most Reliable Method
This is the most accurate way to determine your bolt pattern. Grab a ruler or, even better, a caliper for more precise measurements. Now, depending on whether you have an even or odd number of bolt holes, the measurement you need to take differs slightly.
Even Number of Bolts (e.g., 4, 6)
Measure the distance directly across the hub from the center of one bolt hole to the center of the bolt hole directly opposite it. This measurement is your bolt pattern diameter. For example, if you measure 4 inches across, your bolt pattern is 4 on 4, often written as 4x4. If you have 6 bolts and measure 6 inches across, your bolt pattern is 6 on 6, or 6x6.
Odd Number of Bolts (e.g., 3, 5)
Measuring directly across isn’t possible with an odd number of bolts. Instead, you need to measure from the center of one bolt hole to the outermost edge of the hub directly opposite the bolt hole. Then, multiply this measurement by two to get the diameter. While this method works, it’s a little less accurate than measuring directly across with even-numbered bolt patterns. Double-checking your measurement is a good idea.
Let’s take a look at a practical example. Imagine your go-kart has 5 bolt holes. You measure from the center of one bolt hole to the opposite outer edge of the hub and get a measurement of 2.5 inches. Multiplying this by two gives you a diameter of 5 inches. So, your bolt pattern would be 5 on 5, written as 5x5.
Sometimes, especially with smaller go-karts, you’ll find metric bolt patterns. Make sure your ruler or caliper can measure in both inches and millimeters to be completely prepared. If you’re measuring in millimeters, stick to millimeters for the entire process, and the same goes for inches. Mixing units will only lead to confusion.
It’s always a good idea to take multiple measurements to ensure accuracy. If you’re unsure, you can always contact the go-kart’s manufacturer or a local go-kart shop. They’ll be happy to assist you in identifying the bolt pattern.
Checking Existing Wheels or Documentation: A Quick but Less Reliable Option
Often, the bolt pattern is stamped somewhere on the back of your existing wheels. Look closely – it might be small or hidden amongst other markings. Alternatively, check your go-kart’s owner’s manual; sometimes, it lists the specifications, including the bolt pattern. Be aware that aftermarket wheels might not reflect the original bolt pattern, and manuals can be misplaced, making this method less reliable than direct measurement.
Common Go Kart Bolt Patterns
While you should always measure to be sure, some bolt patterns are more common in go-karts than others. Knowing these common patterns might give you a starting point or help you double-check your measurements.
| Number of Bolts | Common Bolt Pattern Diameter (inches) | Common Bolt Pattern Diameter (mm) |
|---|---|---|
| 4 | 4, 3 | 100, 76 |
| 5 | 5 | 127 |
| 6 | 6 | 152 |
Keep in mind this table isn’t exhaustive. There are other bolt patterns out there, so measuring is always the best way to be 100% certain.
Visually Inspecting the Hub for Bolt Holes
One of the most straightforward ways to determine your go-kart’s hub bolt pattern is by visually inspecting the hub itself. This hands-on approach often yields immediate results and requires minimal tools.
Direct Measurement
Grab a ruler or preferably a caliper for more precise measurements. Carefully measure the distance between the center of one bolt hole to the center of the bolt hole directly across from it. This measurement represents the diameter of your bolt circle. If you have an odd number of bolt holes, things get a bit trickier. You’ll need to measure from the center of one bolt hole to the furthest point on the opposite side of the hub – not necessarily another bolt hole center. This will give you the diameter. Record this measurement clearly. Sometimes, the hub might have markings indicating the bolt pattern. Look closely for any stamped or etched numbers that could save you some measuring.
Detailed Measurement Procedure
Getting an accurate bolt pattern measurement is crucial for finding the right replacement parts. Let’s break down the process step by step:
Even Number of Bolts (e.g., 4, 6):
- Clean the hub face: Ensure the hub surface is clean and free of debris, which could interfere with accurate measurements.
- Identify opposite bolt holes: Locate two bolt holes directly across from each other.
- Measure center-to-center: Using a caliper or ruler, carefully measure the distance between the centers of these two opposing bolt holes.
- Record the measurement: Write this measurement down; this is your bolt circle diameter (BCD).
Odd Number of Bolts (e.g., 3, 5):
- Clean the hub face: As with even-numbered bolt patterns, ensure the hub is clean.
- Choose a reference bolt hole: Select any bolt hole as your starting point.
- Measure to the furthest point: Measure from the center of your chosen bolt hole to the furthest point on the opposite side of the hub. This may or may not be the center of another bolt hole.
- Record the measurement: This measurement represents the diameter.
Additional Tips for Accurate Measurement:
- Use a caliper: Calipers offer greater precision than rulers, minimizing errors.
- Take multiple measurements: Measure a few times and average the results for increased accuracy.
- Check for markings: Look for markings on the hub that might indicate the bolt pattern, saving you the need to measure.
| Number of Bolts | Measurement Method |
|---|---|
| Even (e.g., 4, 6) | Center of one bolt hole to the center of the opposite bolt hole. |
| Odd (e.g., 3, 5) | Center of one bolt hole to the furthest point on the opposite side of the hub. |
Using a Bolt Pattern Gauge
A bolt pattern gauge is a handy tool specifically designed to quickly and accurately determine the bolt pattern of your go kart hubs. These gauges are typically made of plastic or metal and feature a series of holes arranged in common bolt patterns. They work by simply placing the gauge against the hub and seeing which set of holes aligns with your wheel studs or bolts.
How to Use a Bolt Pattern Gauge
Using a bolt pattern gauge is straightforward. First, ensure the hub surface is clean and free of any debris that might interfere with the gauge sitting flush. Next, position the gauge against the hub, making sure it makes good contact with the mounting surface. Rotate the gauge slightly until you find a set of holes that perfectly aligns with your wheel studs or bolts. Once you’ve found a match, the gauge will usually indicate the bolt pattern, either with markings next to the aligned holes or by referring to a chart included with the gauge. If the gauge doesn’t align perfectly with any of the marked patterns, you might have a less common bolt pattern, and another method will be necessary.
Understanding Bolt Pattern Measurements
When you find a matching pattern on your gauge, it’s crucial to understand what the measurement represents. Bolt patterns are typically expressed in two ways, depending on the number of lugs (studs or bolts). For four-lug hubs, the pattern is represented by the diameter of the circle that passes through the center of all four lugs. This is often expressed as 4 x 100mm, meaning four lugs on a 100mm diameter circle. For five-lug and higher hubs, the measurement is usually given as the diameter of the circle created by the center of *opposite* lugs or studs. So a 5 x 114.3mm pattern means five lugs on a circle with a diameter of 114.3mm measured across opposing lug centers, not adjacent ones. Understanding this difference is essential for accurate identification. A slight misinterpretation can lead to purchasing incorrect wheels. It’s always best to double-check your measurements and consult a professional if you have any doubts. Be particularly mindful when dealing with metric and imperial measurements (millimeters versus inches). Some gauges might provide measurements in both units, so pay close attention to which unit you’re reading. Here’s a handy table summarizing some common go-kart bolt patterns:
| Number of Lugs | Common Bolt Patterns (mm) |
|---|---|
| 4 | 4 x 95.25, 4 x 100, 4 x 101.6 |
| 5 | 5 x 100, 5 x 114.3, 5 x 120.7 |
| 6 | 6 x 139.7 |
Remember to always consult your go-kart’s owner’s manual or a reputable dealer if you are unsure about the correct bolt pattern. Using the wrong wheels can be dangerous and can damage your kart. Taking the time to measure carefully ensures you’ll have a safe and enjoyable karting experience.

How to Find a Go-Kart Hub Bolt Pattern
Determining the bolt pattern of your go-kart hub is crucial for selecting compatible wheels and ensuring proper fitment. This process involves identifying the number of bolts and the diameter of the circle they form. While seemingly straightforward, variations in manufacturing and aftermarket modifications can sometimes complicate the process. This guide outlines the most reliable methods for accurate identification.
The most common method involves direct measurement. First, count the number of bolt holes on your hub. Next, if the hub has an even number of bolts, measure the diameter of the circle formed by the center points of opposite bolts. This is referred to as the bolt circle diameter (BCD). If the hub has an odd number of bolts, the process is slightly different. Measure from the center of one bolt hole to the center of the imaginary circle formed by the other bolt holes. Double this measurement to determine the BCD.
For hubs with an odd number of bolts, you can also use a bolt pattern gauge. These gauges have various sized holes representing different bolt patterns. Align the gauge with the bolt holes to find the matching pattern. Consult your go-kart’s owner’s manual or contact the manufacturer or a reputable dealer if direct measurement proves difficult. They may be able to provide the necessary specifications based on the model and year of your go-kart.
Remember to record both the number of bolts and the BCD. This information is essential when ordering replacement wheels or other hub-related components. Accuracy is paramount to ensure safe and proper operation of your go-kart.

Common Questions Regarding Go-Kart Hub Bolt Patterns
What if my hub is damaged?
If your hub is damaged, making accurate measurements can be challenging. If the damage is minimal, try to clean the area around the bolt holes to get a clear view. If the damage is severe, consulting the manufacturer or a reputable dealer for replacement options is recommended. They can provide the correct bolt pattern information based on your go-kart’s specifications. Providing them with the go-kart’s make, model, and year will be beneficial.
What if I can’t find a matching bolt pattern?
If you can’t find a wheel with a matching bolt pattern, adapters or conversion kits may be available. These adapters allow you to use wheels with a different bolt pattern than your hub. However, it is crucial to ensure that any adapter or conversion kit you consider is compatible with your go-kart and meets the necessary safety standards. Consult with a qualified professional before using adapters, as improper installation can lead to safety issues.
What is the difference between bolt pattern and bolt circle diameter (BCD)?
The terms are often used interchangeably, but technically, the bolt pattern refers to the combination of the number of bolts and the BCD. For instance, a 4 x 100 bolt pattern means there are 4 bolts and a BCD of 100mm. Knowing both is essential for proper wheel fitment.
Can I just measure across any two bolts?
No, measuring across any two adjacent bolts will not give you the BCD, especially with more than 4 bolts. With an even number of bolts, you must measure across opposite bolts (diagonally). With an odd number of bolts, you must measure from the center of one bolt hole to the center of the opposite side, as if you were measuring the radius of the bolt circle, then double that number.
