UTV Wheel Bolt Pattern Guide

The One Number That Decides Whether a Wheel Fits

A wheel's bolt pattern is written as two numbers — 4x156, for example. The first is how many lug holes the wheel has; the second is the diameter, in millimeters, of the circle those holes sit on. Get the second number wrong and the wheel physically cannot bolt up, no matter how good it looks or how cheap it is. This guide covers the four patterns that matter on UTVs, which machines run which, how to measure yours in a minute, and the offset question that comes right after.

The Four Patterns

4x156 — Polaris

The most common UTV pattern we sell, and the home pattern of Polaris sport and utility machines — the RZR, Ranger and General crowd. Most of our mounted wheel and tire combo kits are built in 4x156, and nearly every wheel line we stock offers it: the Valor V03 (from $180.00) and the Valor V07 Beadlock ($279.00) are typical examples.

4x137 — Can-Am

Can-Am's pattern. Our Can-Am combo kits are built for the Maverick X3 and the Defender, and the same wheel models usually come drilled for it — the V03 and V07 above both list 4x137 versions at the same prices. One caution from our own kit building: 4x137 is not one-size-fits-all across every brand and year, so on an older or less common machine, measure before you assume.

5x114.3 — The Five-Lug Machines

The newest pattern in the sport: the 2022-and-up RZR Pro R, Turbo R and Pro S run five lugs on a 114.3mm circle (the same spacing as the common 5x4.5" car pattern). Five-lug machines also take a different lug nut setup — 12x1.50 thread with a 20-nut set instead of the usual 16 — which our five-lug combo kits include. Wheels to look at: the Valor V06 Beadlock (15x8, 5x114.3 only, $299.00), the Valor V15 Beadlock (5x114.3 only, $349.00), and 5x114.3 versions of the Valor V13 ($315.00) and Valor V16 ($325.00).

4x110 — ATVs and Smaller Machines

The smallest circle of the four, found on many ATVs and on smaller and older UTVs. Mainstream UTV wheels have mostly moved to 4x156 and 4x137, but 4x110 is still out there — we stock it on select Raceline wheels, including the Raceline Podium Beadlock (14x7 4x110, $230.00) and the Raceline Trophy (14x7 4x110, $189.00).

Two more things worth knowing: a few wheels sidestep the choice entirely — the Valor V08 Beadlock ($319.00) is dual-drilled for both 4x156 and 4x137 in a single wheel. And the Valor V09 even comes in a truck-style 6x139.7 drilling alongside the UTV patterns, for machines that borrow light-truck fitments.

How to Measure Your Bolt Pattern

  • Count the lugs first. Four or five decides which half of this page applies to you.
  • Four-lug wheels are easy: measure from the center of one lug hole straight across to the center of the opposite hole. That distance is the second number — about 156mm means 4x156, about 137mm means 4x137, about 110mm means 4x110.
  • Five-lug wheels have no opposite hole, so the measurement is a center-to-far-edge estimate that is easy to get wrong. Use a bolt pattern gauge, or check your owner's manual and the wheel listing's fitment notes, rather than trusting a tape measure.
  • When in doubt, ask. Send us your machine's year and model and we will confirm the pattern before you spend money — it is a much cheaper conversation than a return.

Offset: The Second Number to Get Right

Offset is the distance from the wheel's hub mounting surface to its centerline, in millimeters. A more positive offset (the +25mm on most of our 14x7 and 15x7 Valor wheels, for example) tucks the wheel in toward the machine and keeps the stance close to stock; zero or negative offsets push the wheel outward for a wider track. You will also see backspacing shorthand like 6+1 or 5+2 on some listings — that is the same idea expressed in inches: on a 7-inch-wide wheel, 6+1 puts most of the width inboard, 5+2 a little less. Why it matters: the wrong offset can rub suspension parts at full lock, fling mud past your fenders, or change how the steering feels. If you are matching a factory setup, stay close to the stock offset; if you are deliberately widening the machine, do it knowingly.

Putting It Together

Pattern first, offset second, then style and finish. Browse the full UTV wheels range, narrow it to Beadlocks or Non-Beadlock wheels, or skip the mounting work entirely with a mounted combo kit built for your pattern.
