Measuring ATV Bolt Pattern
Why Bolt Pattern Matters
If you’re diving into the world of ATVs, understanding the bolt pattern is crucial. This isn’t just a number; it’s the foundation for everything from wheel compatibility to overall performance. Whether you’re upgrading your tires or swapping out rims, knowing how to measure the bolt pattern can save you time, money, and a whole lot of headaches.
What is a Bolt Pattern?
The bolt pattern refers to the arrangement of the bolt holes on your ATV’s wheel hub. It’s typically expressed in a format like 4×110 or 5×115, where the first number indicates how many bolts there are, and the second shows the diameter of the circle formed by the centers of those bolts measured in millimeters. Getting this right is non-negotiable if you plan to keep your ride safe and efficient.
Tools You’ll Need
Before you start measuring, gather a few essential tools:
- Measuring tape or caliper
- Wrench or socket set
- Marker or chalk
Having the right tools on hand makes the job easier and more accurate.
Common Mistakes
One of the biggest blunders people make is assuming that all ATVs of a certain make or model have the same bolt pattern. This is not the case. Different models and even different years can have varying specifications. Always double-check before making a purchase.
Getting Started
Now that you know why it matters and what you’ll need, it’s time to roll up your sleeves. Measuring the bolt pattern is straightforward, but it requires precision. In the next sections, we’ll break down the steps to ensure you get it right the first time. Whether you’re a seasoned mechanic or a newbie, these guidelines will help you nail it without unnecessary fuss.
How to Measure ATV Bolt Pattern Like a Pro
Understanding the Components of a Bolt Pattern
To measure the ATV bolt pattern accurately, you need to grasp its components. The bolt pattern is typically defined by two key numbers: the number of bolt holes and the diameter of the circle that these holes form.
Here’s a breakdown of what you need to know:
- Number of Bolt Holes: This indicates how many bolts secure the wheel to the hub. Common configurations include 4, 5, and sometimes 6 bolts.
- Diameter: This is the distance measured in millimeters from the center of one bolt hole to the center of the bolt hole directly across from it. This is known as the bolt circle diameter (BCD).
Tools Required for Measurement
Before you start measuring, gather the following tools:
- Measuring tape or digital caliper
- Wrench or socket set to remove the wheel
- Marker or chalk for marking
- Paper and pen for noting measurements
Having these tools will streamline the process and ensure accuracy.
Step-by-Step Guide to Measuring Bolt Pattern
Follow these steps to measure your ATV’s bolt pattern:
- Remove the Wheel: Start by safely lifting your ATV and removing the wheel using the appropriate wrench or socket. Make sure the ATV is stable and secured with jack stands.
- Identify Bolt Holes: Look closely at the wheel hub to identify the bolt holes. Count how many there are. This is your first number in the bolt pattern.
- Measure the Diameter: To measure the diameter, use a caliper or measuring tape. If you have an even number of bolt holes (like 4 or 6), measure from the center of one hole to the center of the hole directly across from it. If you have an odd number of holes (like 5), measure from the center of one hole to the center of the hole next to it, then multiply that measurement by 1.1547 to get the BCD.
- Record Your Measurements: Write down the number of bolt holes and the diameter you measured. This will give you your bolt pattern (e.g., 4×110).
Measuring Odd and Even Bolt Patterns
It’s essential to know how to measure both odd and even bolt patterns correctly. Here’s a handy table to clarify the differences:
| Type of Bolt Pattern | Number of Holes | Measurement Method | Example |
|---|---|---|---|
| Even Number of Holes | 4, 6 | Measure directly across | 4×110 |
| Odd Number of Holes | 5 | Measure to the next hole, multiply by 1.1547 | 5×115 |
Common Bolt Patterns for ATVs
Different ATV manufacturers often have specific bolt patterns. Here’s a list of some common ones:
- Honda: 4×110
- Yamaha: 4×115
- Polaris: 4×156
- Kawasaki: 4×136
- Can-Am: 4×137
Always verify your specific model’s bolt pattern before making any purchases.
Tips for Accurate Measurement
To ensure you get the most accurate measurement possible, keep these tips in mind:
- Double-check your measurements before recording them.
- Use a digital caliper for precision.
- Make sure the wheel hub is clean and free of debris to avoid interference.
- If you have access to a factory service manual, consult it for specifications.
Final Thoughts on Bolt Patterns
Measuring your ATV’s bolt pattern is a straightforward process, but it requires attention to detail. Knowing how to do this correctly will help you make informed decisions when upgrading or replacing wheels. Avoid the common pitfalls, and you’ll keep your ATV running smoothly and safely.

Legal Aspects of ATV Modifications
When it comes to modifying your ATV, especially in terms of wheels and tires, there are legal considerations you should be aware of:
Local Regulations
Each state or region may have specific regulations regarding vehicle modifications. Here are some points to keep in mind:
- Noise Regulations: Some areas have laws limiting the noise levels of ATVs, which can be affected by wheel and tire changes.
- Width Restrictions: Modifying wheel size can change the overall width of your ATV, which may violate local road use regulations.
- Safety Standards: Ensure that any modifications comply with safety standards set by local authorities.
Insurance Considerations
Modifying your ATV can also impact your insurance coverage:
- Inform Your Insurer: Always inform your insurance company about modifications, as failure to do so could void your policy.
- Coverage Limits: Some aftermarket parts may not be covered under your existing policy.
Real-World Examples
Consider the following scenarios:
- Scenario 1: An ATV owner replaces their stock wheels with larger aftermarket ones for better traction. They didn’t check local regulations and found themselves facing fines for exceeding width limits.
- Scenario 2: Another owner swapped out their wheels but failed to inform their insurance provider. After a minor accident, they discovered their coverage was void due to the unreported modification.
Being aware of these factors can save you from unnecessary issues down the road.
