4/137 bolt pattern wheels fit the factory hub on most Polaris RZR trims and several Can-Am Maverick Trail and Sport models — four lug holes spaced evenly across a 137mm bolt circle. Get that number wrong by even a few millimeters and the wheel won't center on the hub, no matter how close the lug count looks on paper. The stamped number on your OEM wheel or the spec page in your owner's manual is the only reliable source — matching by eye or by tire-shop guesswork is how mismatched wheels end up back in a box in 2026.
- 4/137 bolt pattern wheels fit most Polaris RZR and Can-Am Maverick Trail/Sport hubs — confirm before ordering.
- 4/156 and 4/136 look close on paper but won't seat on a 4/137 hub without an adapter.
- Bolt circle diameter, lug count, hub bore, and offset all have to match — pattern alone isn't enough.
- Wheel adapters convert one pattern to another but add stack height and stress on wheel studs.
- Kawasaki KRX1000 runs 5/114.3, not 4/137 — check your model year before buying wheels.
Why this matters
Bolt pattern mismatch is one of the most common reasons UTV owners return aftermarket wheels — the wheel looks right in photos, ships fine, and then simply won't sit flat on the hub. R1 Industries stocks wheel and tire packages built to the patterns Polaris, Can-Am, and Kawasaki actually use, and getting the pattern wrong before checkout costs a return shipping label and a week of downtime you didn't plan for in 2026.
A wheel that's off by even 1mm on bolt circle diameter can sometimes still thread onto the studs — it just won't center. That off-center fit shows up as vibration at speed, and vibration on rocky terrain works lug nuts loose over a season of riding. That's not a cosmetic problem on a machine headed to the dunes or down a rock trail.
How to match bolt patterns when buying UTV wheels
Matching a bolt pattern correctly takes five checks, done in this order:
- Find the factory pattern. It's stamped on the back of your OEM wheel or listed in the spec section of your owner's manual — never guess from lug spacing in a photo.
- Confirm bolt circle diameter (BCD) in millimeters. A "5x4.5-inch" pattern and a 5/114.3mm pattern are the same measurement written two different ways — sellers list either unit, so check which one your listing uses before comparing.
- Match lug count first. A four-lug wheel and a five-lug wheel are never interchangeable, regardless of how close the BCD numbers land.
- Check hub-centric bore. The wheel has to center on the hub itself, not just hang off the lug studs — a hub-bore mismatch causes the same vibration problem as a wrong BCD, even when the lug pattern is correct.
- Verify offset. The wrong offset pushes the tire into the A-arm or out past the fender edge, even when the bolt pattern matches perfectly.
When your UTV's factory pattern doesn't match the wheel you actually want, a bolt pattern adapter — like the 5/114.3-to-4/156 adapter used on some Polaris and Can-Am crossover builds — converts one pattern to another. Adapters add stack height between hub and wheel, so treat them as a fitment bridge for a hard-to-find wheel, not the first option when a direct-fit wheel already exists in your pattern.
Common UTV bolt patterns compared
| Bolt Pattern | Lug Count | Common UTV Models | Best For |
|---|---|---|---|
| 4/137mm | 4 | Polaris RZR (most trims), Can-Am Maverick Trail/Sport | Direct-fit RZR and Maverick Trail wheel swaps |
| 4/156mm | 4 | Can-Am Maverick X3, Commander, Defender HD8/HD9 | X3 and Commander owners upgrading to beadlock wheels |
| 4/136mm | 4 | Yamaha YXZ1000R, Kawasaki Teryx, older Arctic Cat Wildcat | Yamaha and Kawasaki trail builds |
| 5/114.3mm (5x4.5") | 5 | Kawasaki KRX1000, select newer Can-Am models | KRX1000 owners running larger beadlock setups |
| 6x139.7mm | 6 | Can-Am Maverick R | Maverick R heavy-duty wheel and tire packages |

4/137 Pattern: Which UTVs Use It
4/137 is the bolt pattern stamped on most Polaris RZR trims, including the RZR XP 1000 and RZR Pro XP lines, along with several Can-Am Maverick Trail and Sport models. It's the pattern to check first if you're shopping wheels for a stock RZR in 2026 — direct-fit options in 4/137 outnumber anything that would require an adapter. Buy direct-fit 4/137 wheels if your RZR or Maverick Trail is still on the factory hub.
4/156 Pattern: Which UTVs Use It
4/156 shows up on the Can-Am Maverick X3 and Commander lines and on Polaris Defender HD8 and HD9 trims. Beadlock wheel builders lean heavily on this pattern because the X3 platform is one of the highest-volume aftermarket wheel markets going into 2026 — beadlock wheels built for the RZR Pro R run a different bolt circle entirely, so don't assume an X3 wheel and a RZR Pro R wheel are interchangeable just because both are beadlocks. Verify X3 vs. RZR Pro R fitment separately before you order.
4/136 Pattern: Which UTVs Use It
4/136 is the pattern on Yamaha YXZ1000R, Kawasaki Teryx, and older Arctic Cat Wildcat models. It sits close in appearance to 4/137 — one millimeter apart on the bolt circle — but the two are not interchangeable without an adapter. Confirm 4/136 specifically if you own a YXZ1000R or Teryx; don't assume it matches a RZR wheel.
5/114.3 Pattern: Which UTVs Use It
5/114.3mm, sometimes listed as 5x4.5-inch, is the pattern on the Kawasaki KRX1000 and several newer Can-Am models. Five-lug wheels in this pattern run a wider selection of aftermarket beadlock options than most four-lug UTV patterns, mainly because the same BCD is shared with a lot of full-size truck and Jeep wheels. KRX1000 owners get the widest aftermarket wheel selection of any pattern on this list.
Why bolt patterns vary across UTV brands
- Each manufacturer standardizes on a bolt circle diameter that fits its own hub and axle tooling — Polaris, Can-Am, and Kawasaki don't share parts.
- Model generations shift: a newer trim under the same nameplate can carry a different hub than an older one from the same brand.
- Heavier UTVs with bigger brake rotors often need a wider bolt circle just to clear the caliper.
- Aftermarket beadlock wheel makers build to the highest-demand patterns first, which is why 4/156 and 5/114.3 show up in more wheel options than less common patterns.
- Wheel spacers and pattern adapters exist specifically to bridge gaps the aftermarket wheel market doesn't cover directly.
Can I put 4/156 wheels on a 4/137 hub?
4/137 and 4/156 differ by 19mm across the bolt circle, so a 4/156 wheel will not bolt directly onto a 4/137 hub without a pattern adapter. Forcing lug nuts onto studs that don't align puts uneven load on the threads and can strip them.
Does a wheel pattern adapter weaken the wheel mount?
A wheel pattern adapter adds stack height between the hub and the wheel, which is why off-road builders treat it as a fitment bridge rather than a permanent daily-trail setup. It works fine for a seasonal wheel swap, but it's less ideal on a UTV that sees rock crawling every weekend.
What bolt pattern does the Kawasaki KRX1000 use?
The Kawasaki KRX1000 uses a 5/114.3mm bolt pattern, shared with several newer Can-Am models, and it is not interchangeable with the 4/137 pattern found on most Polaris RZR trims. Confirm the exact model year before ordering — hub designs across the KRX lineup have changed more than once.
FAQ
What is a 4/137 bolt pattern?
A 4/137 bolt pattern has four lug holes spaced across a 137mm bolt circle, and it's the pattern used on most Polaris RZR trims and several Can-Am Maverick Trail and Sport models. Confirm it against your owner's manual before ordering aftermarket wheels.
Is 4/137 the same as 4/156?
4/137 and 4/156 are not the same — they differ by 19mm across the bolt circle, so wheels built for one pattern won't bolt directly onto a hub built for the other. A pattern adapter is required to run one on the other's hub.
Can I use a bolt pattern adapter on my UTV?
Yes, a bolt pattern adapter converts one lug pattern to another, and options exist for common UTV conversions like 5/114.3 to 4/156. Adapters add stack height, so they work best as a fitment bridge rather than a long-term daily-trail solution.
What bolt pattern does the Kawasaki KRX1000 use?
The Kawasaki KRX1000 uses a 5/114.3mm bolt pattern, shared with several newer Can-Am models. It's not interchangeable with the 4/137 pattern found on most Polaris RZR trims.
How do I find my UTV's bolt pattern?
Check the back of your OEM wheel for a stamped number, or look up the spec section of your owner's manual — both list the exact bolt pattern for your model and year. Guessing from lug spacing photos online is the most common way owners order the wrong wheel.
Will wheel spacers change my bolt pattern?
No, wheel spacers keep the same bolt pattern and just push the wheel further from the hub to change offset — they don't convert one pattern to another. A pattern adapter is a separate part built specifically for that conversion.
Are 4/136 and 4/137 wheels interchangeable?
4/136 and 4/137 are not interchangeable even though they sit only 1mm apart on the bolt circle — that small gap keeps lug studs from lining up. Yamaha, Kawasaki, and older Arctic Cat models use 4/136, while most Polaris RZR trims use 4/137.
Does bolt pattern affect which tires I can run?
Bolt pattern only determines wheel fitment, not tire size — tire diameter and width are set separately by your suspension clearance and gearing. You can run the same tire size across different bolt patterns as long as the wheel itself matches your hub.
One last thing
The pattern number gets all the attention, but hub-centric bore is what actually keeps a wheel from running out of true at speed — a wheel can bolt on perfectly and still vibrate if the bore doesn't match the hub. Check both numbers before you order in 2026, not just the one printed in bold on the listing.
