The Can-Am Defender, a popular side-by-side (SxS) vehicle known for its versatility and ruggedness, comes in several models, each potentially having a different bolt pattern. Understanding your specific Defender's bolt pattern is crucial for selecting the right wheels and tires. This guide will break down the common bolt patterns and help you determine the correct one for your machine.
What is a Bolt Pattern?
Before diving into the specifics of Can-Am Defender bolt patterns, let's define the term. A bolt pattern, also known as wheel bolt pattern or lug pattern, specifies the arrangement of the wheel studs on your vehicle's hub. It's expressed as two numbers:
- PCD (Pitch Circle Diameter): This is the diameter of the circle passing through the centers of the wheel studs. It's measured in millimeters (mm).
- Number of Lug Nuts/Studs: This indicates the number of studs securing the wheel to the hub.
Common Can-Am Defender Bolt Patterns
While several Can-Am Defender models exist, the most common bolt patterns encountered are:
-
4x137mm (4x5.5 inches): This is a fairly standard bolt pattern found on many ATVs and UTVs, including several Can-Am Defender models. It indicates four lug nuts arranged on a circle with a diameter of 137mm (or 5.5 inches).
-
4x156mm (4x6.14 inches): Some Defender models, particularly those with larger wheels and tires, may utilize this less common pattern. It’s crucial to verify your specific model to ensure compatibility.
It's extremely important to note: The specific bolt pattern depends heavily on the year, model, and even trim level of your Can-Am Defender. Always consult your owner's manual or the vehicle's identification plate (VIN plate) for definitive information. This is critical to avoid purchasing incompatible wheels and tires.
How to Find Your Can-Am Defender's Bolt Pattern
Here's a step-by-step guide to determine your Can-Am Defender's bolt pattern:
-
Consult your Owner's Manual: The owner's manual is your best resource. It will clearly specify the bolt pattern for your specific machine.
-
Check the Vehicle's Identification Plate (VIN Plate): This plate typically contains information about your vehicle's specifications, including the bolt pattern. Locate this plate—often found on the frame, under the seat, or inside the glovebox.
-
Measure Your Existing Wheels (Less Accurate Method): As a last resort, you can carefully measure your current wheels. Measure the diameter of the circle passing through the center of each lug nut (PCD) and count the number of lug nuts. However, this method is less accurate and should only be used if the other methods fail.
What Happens if You Use the Wrong Bolt Pattern?
Using the wrong bolt pattern can have serious consequences:
- Wheel Failure: The wheels might not mount securely, leading to potential wheel detachment while driving, posing a significant safety hazard.
- Damage to Hub: Incorrectly mounted wheels can damage the wheel studs or hub, requiring costly repairs.
- Uneven Wear: Poor fitment can cause uneven tire wear and handling issues.
Beyond Bolt Pattern: Other Wheel Considerations
While the bolt pattern is paramount, several other factors should be considered when selecting new wheels and tires for your Can-Am Defender:
- Wheel Offset: This determines how far the wheel is mounted in relation to the hub mounting surface.
- Backspacing: The distance between the wheel mounting surface and the innermost part of the wheel.
- Wheel Size and Tire Size: Choose wheels and tires that fit within the vehicle's specifications to avoid rubbing or clearance problems.
By carefully considering all these aspects, you can ensure a safe and comfortable ride in your Can-Am Defender. Always prioritize safety and consult professionals if you are unsure about any aspect of wheel or tire selection.
