We’ll cover the real-world benefits, the essential supporting mods, potential problems to watch for, and a step-by-step process to get it done right in your own garage. Let’s get your rig ready to dominate.
Why Go Big? The Real-World Benefits of Polaris Xpedition 33s
Jumping to a 33-inch tire is more than just an aesthetic choice. While they certainly look incredible, the functional advantages are what truly make this a top-tier upgrade for any serious off-roader. This is where your machine’s capability fundamentally changes.
More Than Just Looks: Tangible Performance Gains
The core benefits of polaris xpedition 33s are all about performance on the trail. A larger tire changes the geometry and contact patch of your vehicle, directly impacting how it interacts with the terrain. You’re not just lifting the body; you’re lifting the axles and everything underneath them.
Increased Ground Clearance
This is the most obvious benefit. A larger tire directly increases the distance from your differentials, A-arms, and skid plates to the ground. That extra inch or two of clearance can be the difference between sliding over a rock and getting high-centered, ending your day early.
Improved Traction and Footprint
A 33-inch tire has a significantly larger contact patch—the amount of rubber touching the ground at any given moment. When you air down for technical terrain, that footprint expands even more, providing incredible grip on slick rock, loose dirt, and mud. More grip means more control and more confidence.
Enhanced Obstacle Crawling
The larger rolling diameter of a 33-inch tire creates a better “angle of attack.” Think of it like a monster truck tire rolling over a car versus a skateboard wheel. The larger tire can climb up and over logs, ledges, and rocks more easily, rather than being stopped dead in its tracks.
Before You Buy: The Essential Pre-Upgrade Checklist
Here’s a hard truth from the shop floor: you can’t just slap 33s on a stock Xpedition and expect it to work flawlessly. The factory components are engineered for stock tire sizes. Increasing tire size and weight puts significant stress on the entire drivetrain. Proper planning is crucial.
It’s Not Just About Tires: Supporting Mods are Key
To do this upgrade correctly and reliably, you need to think of it as a system. The tires are just one part. Here are the other components you absolutely need to consider to maintain performance and prevent costly damage.
Lift Kits: Creating the Necessary Space
First and foremost, you need room. A quality 2-3 inch lift kit is generally recommended to provide the fender clearance needed for a 33-inch tire. This prevents the tire from rubbing on the plastics or suspension components during compression and turning, which can destroy both your tires and your machine.
Clutch Kits: Restoring Lost Power and Belt Life
This is the most overlooked—and most critical—supporting mod. Larger, heavier tires change your final drive ratio, making the engine and transmission work much harder. A clutch kit recalibrates your CVT system to account for this. Without it, you’ll experience sluggish acceleration, poor back-shifting on hills, and, most importantly, you will burn through drive belts at an alarming rate.
Axles and Drivetrain: Beefing Up for the Strain
The added leverage and weight of 33s put a massive strain on your stock axles, especially when you’re in a bind on the trail. While not always required immediately, consider upgrading to heavy-duty axles from brands like RCV or Turner Cycles as a preventative measure, especially if you’re an aggressive driver.
Wheels and Offset: Getting the Stance Right
Your wheel choice matters. A wheel with a different offset (like a 4+3 or 5+2) can push the tire out slightly, providing better clearance from suspension components. However, going with too much offset can increase stress on wheel bearings, so find a happy medium. Ensure your new wheels have the correct bolt pattern for your Xpedition.
How to Fit Polaris Xpedition 33s: A Step-by-Step Guide
Ready to turn some wrenches? This section provides a general overview of the installation process. This is a fantastic DIY project, but if you’re ever unsure, don’t hesitate to consult a professional mechanic. This is a comprehensive polaris xpedition 33s guide to get you started.
Safety First: Gearing Up for the Job
Before you start, gather your tools and prioritize safety. You’ll need:
- A reliable floor jack and heavy-duty jack stands (never work under a vehicle supported only by a jack).
- A torque wrench.
- A full socket and wrench set (both metric and standard).
- Wheel chocks.
- Safety glasses.
Step 1: Install Your Lift Kit (If Applicable)
If you’re installing a lift, do this first. Follow the manufacturer’s instructions to the letter. This typically involves lifting the vehicle, removing the wheels and shocks, installing the lift brackets or new A-arms, and then reassembling everything. Take your time and double-check every bolt.
Step 2: Prepare the Wheel Wells (Trimming and Clearancing)
Even with a lift, you may need to do some minor trimming of the plastic fender liners, especially at the front. With the suspension at full compression and the wheel turned, you’ll see where it might rub. Use a utility knife or a small cutting tool to carefully remove small amounts of plastic until you have adequate clearance.
Step 3: Mount and Balance Your New Tires
Unless you have a tire machine at home, you’ll need to take your new wheels and tires to a local tire shop to have them mounted and balanced. An unbalanced tire will cause significant vibration at speed, which is uncomfortable and puts extra wear on your suspension components.
Step 4: Install the Wheels and Torque to Spec
With the tires mounted on your new wheels, install them on your Xpedition. Tighten the lug nuts in a star pattern to ensure the wheel is seated evenly. Use your torque wrench to tighten them to the factory specification found in your owner’s manual. This is a critical safety step!
Step 5: The All-Important Test Drive and Rub Check
Start with a slow-speed test drive in an open area. Turn the steering wheel lock-to-lock in both directions. Drive over a few small bumps to cycle the suspension. Listen and feel for any signs of rubbing. If you find any, identify the contact point and perform additional trimming as needed.
Common Problems with Polaris Xpedition 33s (And How to Fix Them)
Running bigger tires introduces new variables, and with them, potential issues. Being aware of the common problems with polaris xpedition 33s helps you diagnose and fix them before they become major headaches.
The Dreaded Rub: Identifying and Solving Clearance Issues
Even after initial checks, you might find rubbing under heavy suspension compression on the trail. The most common contact points are the front fender liner near the firewall and the outer edge of the fender flare. The fix is almost always careful trimming.
Power Loss and Sluggish Performance
If your Xpedition feels like a dog after the upgrade, your clutch is the culprit. The stock clutch calibration can’t handle the extra rotating mass. Installing a clutch kit specifically designed for your tire size and riding style is the only correct solution. It will restore that snappy, responsive feel.
Premature Belt Wear and How to Prevent It
Smelling burning rubber on a steep climb? That’s your drive belt slipping and overheating. This is another symptom of an un-clutched machine. A proper clutch kit and using low gear when climbing or crawling are the best polaris xpedition 33s best practices to preserve belt life.
Drivetrain Stress: Listening for Trouble
Pay attention to new noises. Clicks or pops while turning can indicate a failing CV joint in your axle. A humming or grinding sound that changes with speed could be a wheel bearing. Early detection of these issues can save you from a much more expensive repair down the road.
The Long Haul: Your Polaris Xpedition 33s Care Guide
Your work isn’t done after the installation. A modified vehicle requires a more attentive owner. This simple polaris xpedition 33s care guide will keep your rig reliable and ready for adventure.
Tire Pressure is Everything
Don’t run street pressure on the trail. For general trail riding, a pressure between 10-15 PSI is a good starting point. For slow-speed rock crawling, you might go as low as 6-8 PSI. Experiment to find what works best for your tires and terrain, and always air back up before hitting high-speed roads.
Regular Rotations for Even Wear
Just like on your truck, rotating your tires every 500-1000 miles will promote even tread wear and extend their life. This is a great time to inspect your wheels, brakes, and suspension components as well.
Drivetrain Inspection Best Practices
After every major ride, do a quick walk-around. Check for torn CV boots, play in your wheel bearings (by grabbing the tire at the top and bottom and trying to wiggle it), and any loose suspension bolts. A five-minute check can prevent a weekend-ending failure.
A Note on Sustainable and Eco-Friendly Off-Roading
Having a capable machine means we have a greater responsibility to protect the trails we love. Following sustainable polaris xpedition 33s principles is easy. Stay on designated trails, avoid creating new bypasses, and pack out everything you pack in. Properly maintaining your vehicle prevents fluid leaks, and choosing a quality, long-lasting tire reduces waste. These are the hallmarks of an eco-friendly polaris xpedition 33s setup.
Frequently Asked Questions About Polaris Xpedition 33s
Can I fit 33s on a stock Polaris Xpedition without a lift?
No, this is not recommended. While you might be able to bolt them on, you will experience severe rubbing on the fender liners and possibly the suspension components as soon as the suspension compresses or you turn the wheel. A lift kit is essential for proper clearance.
Do I really need a clutch kit for 33-inch tires?
Yes, absolutely. We consider it a mandatory part of the upgrade. Without it, you will have poor performance, dramatically increased belt wear, and you put unnecessary strain on your entire powertrain. It’s the key to making the machine work correctly with the larger tires.
What’s the best tire pressure for 33s on the trail?
This depends on your tire construction and the terrain. A great starting point is 12 PSI. For rocky, low-speed sections, you can drop down to 8-10 PSI for better grip. For high-speed fire roads, 14-16 PSI might feel more stable. Always carry a portable air compressor to adjust as needed.
Will upgrading to 33s void my warranty?
This can be a grey area. Technically, a manufacturer can only deny a warranty claim if they can prove your modification directly caused the failure. For example, if you break an axle with 33s, they will likely deny the claim. However, if your radio stops working, they should still cover it. Always check with your dealer for their specific policy.
Making the move to 33-inch tires is one of the most rewarding upgrades for your Polaris Xpedition. By planning ahead, installing the right supporting mods, and following a few simple care practices, you can build a machine that’s not only more capable but also reliable for years of trail adventures. Take your time, do it right, and get ready to conquer terrain you used to go around.
Now get out there and get those tires dirty. Stay safe and have fun!
