Let’s be honest. One of the first things you eyeball on your Can-Am Commander is the tires. You know that a beefier, more aggressive set of rubber can completely transform your machine’s capability and look. But then the questions start piling up: How big can I actually go? Will they rub? Do I need a lift? It’s a common crossroads for every Commander owner looking to level up their ride.
You’re in the right place. We’re going to cut through the noise and forum chatter. This isn’t just a list of numbers; this is your complete, hands-on guide from the shop floor at FatBoysOffroad. We promise to walk you through everything you need to know about your can am commander tire size, from decoding what you have now to safely installing the perfect upgrade.
In this guide, we’ll cover how to choose the right size for your stock or lifted machine, the critical supporting mods you can’t ignore (hello, clutch!), and how to avoid the common, costly mistakes we see all the time. Let’s get those new tires picked out and get you back on the trail.
Understanding Your Stock Can-Am Commander Tire Size
Before you can go bigger, you need a solid baseline. Knowing your factory tire size is the first step in any successful upgrade. It gives you the reference point for calculating gains in clearance and understanding what modifications might be needed.
How to Read Your Tire Sidewall
That string of numbers on your tire isn’t just for decoration. It’s the tire’s spec sheet. Let’s take a common example, like 27×9-14.
- 27: This is the overall height of the tire in inches when inflated. This is the most important number when discussing ground clearance.
- 9: This is the width of the tire in inches. A wider tire can offer more floatation on soft terrain like sand or mud.
- 14: This is the diameter of the wheel (or rim) in inches that the tire is designed to fit. You must match this number to your wheels.
Go take a look at your machine right now. Understanding this simple code is a fundamental part of our can am commander tire size guide.
Common Stock Sizes by Commander Model
Can-Am has offered a few different tire sizes over the years, depending on the model and trim package (like DPS, XT, XT-P, or MAX). Generally, you’ll find stock sizes ranging from 26 to 28 inches. For example, many recent models come equipped with 27-inch or 28-inch XPS Trail Force or Maxxis Bighorn 2.0 tires.
Always double-check your specific machine, as packages can change year to year. Your owner’s manual or the tire sidewall is your ultimate source of truth.
The Benefits of Upgrading Your Can-Am Commander Tire Size
Why go through the trouble of changing your tire size? The payoff is huge, both in performance and aesthetics. Here are the key benefits of a well-planned tire upgrade.
Increased Ground Clearance for Obstacles
This is the big one. Swapping from a 27-inch tire to a 30-inch tire gives you an immediate 1.5 inches of extra ground clearance under your differentials. That might not sound like much, but it’s the difference between scraping over a rock or log and getting hung up completely.
Improved Traction and Floatation
Larger tires have a bigger contact patch—more rubber touching the ground at any given moment. This translates to superior traction in mud, sand, and on slick rock faces. The larger volume also allows you to air down for even better grip and a smoother ride over rough terrain.
Enhanced Stability and Stance
Going with a slightly wider tire, or pairing your new tires with offset wheels, can widen your Commander’s track width. This lowers its center of gravity and makes the machine feel much more planted and stable, especially on off-camber trails or during high-speed cornering.
Your Complete Can-Am Commander Tire Size Guide: How Big Can You Go?
This is the million-dollar question. The answer depends on your machine’s setup and your willingness to make supporting modifications. Here’s a breakdown of how to can am commander tire size selection works in the real world.
The “No-Lift” Sweet Spot: What Fits on a Stock Machine?
For most modern Can-Am Commanders (2021+), you can typically fit a 29-inch or even a 30-inch tire on the stock suspension without major issues. Older generation Commanders are often more limited to 28 inches.
Pro Tip: The limiting factor is often the front tires rubbing on the fender or firewall at full steering lock and during suspension compression. A true-to-size 30-inch tire is usually the absolute max before you need to consider other mods.
Going Bigger: When You Need a Lift Kit and Fender Flares
Want to run 31-inch, 32-inch, or even larger tires? You’re entering lift kit territory. A simple 2 to 3-inch bracket lift will reposition your shocks to give you the physical space needed to clear those bigger tires. This is one of the most popular can am commander tire size tips for serious mudders and rock crawlers.
Remember, a lift kit raises your center of gravity, so consider adding wheel spacers or offset wheels to regain that stability.
The Clutch Conundrum: Why Bigger Tires Demand Clutch Work
This is the single most overlooked step. Larger, heavier tires change your machine’s final drive ratio. Your stock clutch is calibrated for stock tires. When you add rotational mass, you put immense strain on your belt and clutch components.
Symptoms of an un-clutched setup with big tires include:
- A sluggish, “bogged down” feeling on acceleration.
- Poor back-shifting when letting off the gas.
- Frequent smoked or broken drive belts.
Investing in a quality clutch kit (with new springs and weights) is not optional; it’s essential to recalibrate your CVT for the new tires. It restores lost performance and protects your drivetrain from expensive damage.
Common Problems with Can-Am Commander Tire Size Upgrades (And How to Avoid Them)
Jumping to a bigger tire without proper planning can lead to headaches. Here are the most common problems we see and how you can get ahead of them.
Tire Rubbing: The Arch-Nemesis of Big Tires
Even if a tire seems to fit in the garage, it might rub under real-world conditions. Before hitting the trail, turn your steering wheel to full lock in both directions. Use a floor jack to safely compress the suspension on each corner to simulate bumps and turns. Check for any contact with the fender wells, suspension arms, or frame.
Drivetrain Stress: Broken Axles and Worn Bearings
The added weight and leverage of big tires put more stress on your axles, ball joints, and wheel bearings. Be prepared for these to become wear items that need more frequent inspection and replacement. Upgrading to heavy-duty axles from brands like SuperATV or Rhino is a smart move if you’re running 32-inch tires or larger and ride hard.
Power Loss and Inaccurate Speedometer
As mentioned, you will feel a loss of “snap” off the line without a clutch kit. Additionally, your speedometer is calibrated for the stock tire height. A larger tire will rotate fewer times per mile, meaning your speedometer will read slower than your actual speed. You can correct this with a digital calibration tool if accuracy is important to you.
Can-Am Commander Tire Size Best Practices for Longevity and Safety
You’ve made the investment, now let’s make it last. Following these best practices will ensure you get the most out of your new setup.
Choosing the Right Tire for Your Terrain
Don’t just buy the most aggressive-looking tire. Think about where you ride 80% of the time.
- All-Terrain: Perfect for riders who tackle a mix of hardpack, trails, and occasional mud. Look for a durable 6 or 8-ply radial.
- Mud Tires: Characterized by deep, widely spaced lugs. They excel in deep mud but can be rough and wear quickly on hard surfaces.
- Rock Crawling: These tires often have a softer, stickier compound and flexible sidewalls for gripping rock faces.
Proper Mounting and Torque Specs
When installing your new wheels and tires, always tighten the lug nuts in a star pattern to ensure the wheel is seated evenly. Use a torque wrench and tighten to the manufacturer’s specification found in your owner’s manual (typically around 80-100 ft-lbs). Re-check the torque after your first 25-50 miles.
Setting the Correct Tire Pressure (PSI)
The right PSI is crucial for performance, ride quality, and tire life. A good starting point for general trail riding is 12-15 PSI. For sand or snow, you might air down to 8-10 PSI for better floatation. For heavy loads or high-speed hardpack, you might go up to 18 PSI. This is a key part of any good can am commander tire size care guide.
Thinking Green: Sustainable and Eco-Friendly Can-Am Commander Tire Size Choices
Being an off-roader and being mindful of our impact aren’t mutually exclusive. When it comes to tires, making sustainable choices is easier than you think.
Choosing a high-quality, durable tire from a reputable brand is the most sustainable can am commander tire size decision you can make. A tire that lasts 5,000 miles instead of 2,000 means less waste in landfills and less consumption of raw materials.
Furthermore, maintaining proper air pressure reduces rolling resistance, which can slightly improve fuel efficiency on the trail. When your old tires are finally worn out, contact your local tire shop or waste management facility about proper recycling programs. Never dump old tires in the wild.
Frequently Asked Questions About Can-Am Commander Tire Size
What is the largest tire I can put on a stock Can-Am Commander?
For most modern (2021+) models, a 30×10 tire on all four corners is generally the largest you can fit without a lift kit. You may experience very minor rubbing at full lock under compression. For older models, 28 inches is often a safer bet without modifications.
Do I really need to change my clutch if I get bigger tires?
Yes, absolutely. We consider it a mandatory upgrade for any tire two inches or more over stock size. It will save your belt, improve performance, and make the machine much more enjoyable to drive. Skipping this step is asking for trouble.
Will bigger tires void my warranty?
This can be a grey area. Technically, dealers must prove that your modification directly caused a failure. For example, if your radio stops working, they can’t blame your tires. However, if you break an axle while running massive 35-inch tires, they will likely deny that warranty claim. It’s best to check with your local dealer.
How do bigger tires affect my Commander’s handling?
You’ll notice a few things. The ride will often feel smoother over small bumps due to the larger air volume. The steering may feel slightly heavier. If you’ve also made the machine wider, it will feel more stable, but if you’ve only gone taller (with a lift), the center of gravity will be higher, requiring more caution in corners.
Choosing the right can am commander tire size is one of the most rewarding upgrades you can make. It enhances performance, boosts capability, and gives your machine a bold new look. By following this guide, you can make an informed choice, avoid common pitfalls, and set your Commander up for success on any terrain. Plan your upgrade, do the supporting mods, and get ready to conquer the trail.
