Ever found that perfect, aggressive set of wheels for your rig, only to get hit with a wave of uncertainty? Will they actually fit? It’s a classic headache for any off-road enthusiast looking to upgrade their machine. Getting it wrong means wasted time, wasted money, and a major safety risk on the trail.
I promise this guide will completely demystify the can am commander bolt pattern for you. We’re going to break it down into simple, easy-to-understand terms so you can choose and install your next set of wheels with total confidence.
In this comprehensive guide, we’ll cover what the bolt pattern is, the exact specs for your Commander model, how to measure it yourself, and the common problems to avoid. Let’s get your rig looking and performing its best.
What Exactly *Is* a Bolt Pattern and Why Does It Matter?
Think of the bolt pattern as the specific fingerprint of your vehicle’s wheel hub. It’s the layout of the lug studs that your wheel bolts onto. If the holes on the wheel don’t perfectly match the studs on your hub, it’s a no-go.
Knowing this spec is non-negotiable for anyone looking to buy aftermarket wheels. It’s the first and most critical piece of fitment information you need. The right fit ensures your wheel is centered and securely fastened, which is crucial for safety and performance, especially when you’re miles from civilization.
Decoding the Numbers: 4×137 Explained
You’ll always see the bolt pattern expressed as two numbers, like 4×137. It’s simpler than it looks.
- The First Number (4): This tells you how many lug studs are on your hub. For the Can-Am Commander, this number is almost always 4.
- The Second Number (137): This is the diameter of an imaginary circle that runs through the center of all the lug studs, measured in millimeters. So, 137 stands for 137mm.
Put it together, and 4x137mm means you have four lug studs arranged in a circle with a diameter of 137 millimeters. This is the standard for most modern Can-Am UTVs.
The Big Three: Bolt Pattern, Offset, and Center Bore
While the bolt pattern is king, it’s only one part of the fitment puzzle. To achieve a perfect setup, you also need to understand two other key measurements.
Wheel Offset: This determines how far in or out your wheels will sit in the wheel wells. A positive offset tucks the wheel in, while a negative offset pushes it out for a wider, more aggressive stance. Getting this wrong can cause your tires to rub on suspension components or fenders.
Center Bore: This is the large hole in the middle of the wheel that fits over the hub. A proper, snug fit (called “hub-centric”) helps center the wheel and supports the vehicle’s weight. A center bore that’s too small won’t fit, and one that’s too large can cause vibrations and put excess stress on your lug studs.
Your Complete Can-Am Commander Bolt Pattern Guide by Model Year
Here at FatBoysOffroad, we believe in getting straight to the point. The great news is that Can-Am has kept things refreshingly simple. This section of our can am commander bolt pattern guide will give you the exact specs you need.
Across all generations and models, the Can-Am Commander has consistently used a single, standard bolt pattern.
The Can-Am Commander bolt pattern is 4x137mm.
This applies to virtually all models, from the early Gen 1 machines to the latest releases. Let’s break it down just to be crystal clear.
Commander 800/1000 (Gen 1: approx. 2011-2020)
- Bolt Pattern: 4x137mm
- Lug Stud Size: M10 x 1.25
Commander (Gen 2: 2021+)
- Bolt Pattern: 4x137mm
- Lug Stud Size: M12 x 1.5
A Note on Lug Nuts and Stud Size
Notice the change in lug stud size between generations. The newer Gen 2 Commanders use a beefier M12 stud, while the older Gen 1 models use a smaller M10 stud.
This is extremely important. You must use the correct lug nuts that match your machine’s stud size and thread pitch. Using M10 nuts on M12 studs simply won’t work, and trying to force them will strip the threads, creating a dangerous situation.
How to Measure Your Can-Am Commander Bolt Pattern Yourself
While we’ve established the Commander’s pattern is 4x137mm, knowing how to measure a bolt pattern is a fundamental skill for any DIY mechanic. It comes in handy when you’re looking at a used set of wheels or just want to double-check your work.
This is a core part of learning how to can am commander bolt pattern fitment works. It’s easy to do with a simple tool.
Tools You’ll Need
- A tape measure or a caliper
- A lug wrench to remove a wheel (if necessary)
Step-by-Step Measurement for 4-Lug Hubs
Measuring a 4-lug pattern is the most straightforward. You don’t need to calculate an imaginary circle.
- Safety First: Make sure your Commander is on level ground, in park, with the parking brake engaged. If you’re removing a wheel, use jack stands for safety.
- Measure Across: Pick one lug stud. Measure from the center of that stud directly across to the center of the stud opposite it.
- Check Your Number: The distance you measure is your bolt pattern diameter. For a Can-Am Commander, this measurement should be 137mm (or approximately 5.4 inches).
That’s it! This simple check confirms you have the right pattern before you spend your hard-earned cash.
Common Problems and Mistakes When Choosing New Wheels
Knowing the bolt pattern is step one, but avoiding common pitfalls is what ensures a successful upgrade. Here are some common problems with can am commander bolt pattern projects that we see all the time.
Ignoring Wheel Offset and Backspacing
A new set of wheels might have the correct 4×137 bolt pattern, but if the offset is wrong, you’re in for a world of hurt. Too much negative offset on a stock machine can cause tires to rub on fenders during turns or suspension compression.
Pro Tip: Stock Can-Am Commander wheels typically have a high positive offset (around +40mm to +55mm). Most aftermarket wheels have less positive or even negative offset to widen the stance. Be sure to check for clearance after installation.
The Wrong Center Bore: A Wobble Waiting to Happen
Many aftermarket wheels are made with a large center bore to fit a wide variety of vehicles (a “lug-centric” design). While these will bolt up, they rely solely on the lug nuts to center the wheel, which can lead to vibrations.
For the best and safest fit, look for wheels with the correct center bore for your Commander or use hub-centric rings. These small rings fill the gap between your hub and the wheel’s center bore, ensuring a perfect, vibration-free fit.
Using the Wrong Lug Nuts (Taper vs. Ball Seat)
Lug nuts aren’t one-size-fits-all. They have different “seat” styles where they contact the wheel. Most aftermarket wheels use a conical or “tapered” seat. Stock Can-Am wheels often use a different style.
Using the wrong seat type means the lug nut won’t make proper contact with the wheel. This prevents it from being torqued correctly and can cause the wheel to come loose. Always use the lug nuts supplied with your new wheels.
The Benefits of Upgrading Your Commander’s Wheels
Understanding the bolt pattern isn’t just about maintenance; it’s about unlocking potential. The benefits of can am commander bolt pattern knowledge open the door to serious upgrades.
Improved Performance and Traction
Aftermarket wheels often allow you to run wider, more aggressive tires. This increases your tire’s contact patch with the ground, giving you dramatically better traction in mud, sand, and on rocky terrain.
Enhanced Durability for Tough Trails
Many aftermarket wheels, especially beadlocks, are built tougher than stock. They are designed to withstand the harsh impacts of off-roading, reducing the risk of a cracked or bent rim that could leave you stranded.
Unbeatable Style and Customization
Let’s be honest—a great set of wheels completely transforms the look of your machine. It’s one of the easiest ways to make your Commander stand out from the crowd and reflect your personal style.
Wheel Spacers and Adapters: Best Practices and Safety Tips
Wheel spacers and adapters can be useful tools, but they must be used correctly. They both bolt to your hub’s existing studs and provide a new set of studs for your wheel to mount on.
Spacers vs. Adapters: What’s the Difference?
Spacers: These simply push the wheel out further from the hub. They use the same bolt pattern as your vehicle (e.g., 4×137 to 4×137). They are used to gain clearance for larger tires or to achieve a wider stance.
Adapters: These actually change the bolt pattern. For example, an adapter could allow you to mount a 4×156 wheel on your 4×137 Commander hub. This is less common in the UTV world but a frequent solution for trucks.
When using either, follow these can am commander bolt pattern best practices:
- Buy from a reputable brand. Cheap, cast aluminum spacers can crack under stress. Insist on high-quality, billet aluminum.
- Ensure they are hub-centric. This is critical for preventing vibrations and ensuring a safe fit.
- Use thread locker (like Loctite) on the nuts that hold the spacer to the hub.
- Torque everything to spec. This is not a place to guess. Use a torque wrench.
Sustainable and Eco-Friendly Choices in Off-Roading
You might not immediately connect this topic with sustainability, but making smart choices matters. A truly sustainable can am commander bolt pattern strategy involves choosing high-quality parts that last. A cheap wheel that cracks or a spacer that fails not only puts you at risk but also creates waste.
Investing in well-made wheels and components from reputable brands is an eco-friendly can am commander bolt pattern practice. It means fewer replacements, less manufacturing waste, and more time enjoying the trails responsibly.
Frequently Asked Questions About the Can-Am Commander Bolt Pattern
Is the Can-Am Commander bolt pattern the same as the Maverick?
Yes, it is. Both the Can-Am Commander and the Can-Am Maverick (including the X3, Sport, and Trail models) use the same standard 4x137mm bolt pattern. This makes it easy to shop for wheels that fit a wide range of Can-Am machines.
Can I use wheels from another brand on my Commander?
You can, but only if the bolt pattern and center bore match. For example, some Kawasaki and Suzuki models also use a 4x137mm pattern. However, you must verify the center bore and offset are compatible with your Commander to avoid fitment issues.
Do I need to re-torque my lug nuts after installing new wheels?
Absolutely. This is a critical safety step. After installing new wheels, drive for about 25-50 miles, then stop and re-torque all lug nuts to the manufacturer’s specification using a torque wrench. Wheels can settle onto the hub, and lug nuts can slightly loosen during this initial period.
