Identifying wheel size, offsets, and the correct bolt pattern is half the battle. Once you know the numbers it gets easier!

 What is a wheel offset?

The offset is the distance from the hub mounting surface to the center line of the wheel. The idea is to know how much, in inches, your wheel will suck in or stick out from the mounting surface of the hub. Not only will this effect the look of your machine but the ride quality and performance as well.

Offsets are measured with two numbers, both numbers together will equal the total width of the wheel.  The first number is the distance from the hub mounting surface to the inner half of the wheel and the second number is from the hub mounting surface to the outer half of the wheel.  When those numbers are equal your hub mounting surface is center, meaning your wheel is not offset.

How does this effect my bike?

  • When the hub is placed toward the outer half of the wheel, like the 5+2 offset, the more the wheel is tucked in under the machine; this improves width clearance by minimizing the overall width of your rig.
  • When the hub is placed toward the inner half of the of the wheel, like the 3+5 offset, the more the wheel sticks out beyond the fender; this will increase the overall width of your rig or “widen your stance”, improve its stability and create room for larger tires.
  • When the hub is placed center of the wheel the numbers are equal; this means the wheel is not offset one way or another. This will make a difference to your rig if you’re currently running stock wheels, most OEM wheels have a positive offset.

MSA Offroad Wheels does things a little differently, they measure their wheels in millimeters and identify offsets with three terms, Zero, Negative and Positive. The positive or negative number is the measurement in millimeters from the centerline of the wheel to the hub mounting surface. For example: +10mm or -47mm.  Although not as easy to understand as 5+2 or 4+3, the  +/-mm offset provides a more precise measurement.
  • Zero Offset – The hub mounting surface is even with the center line of the wheel.
  • Positive – The hub mounting surface is toward the front or outer half of the wheel.
  • Negative – The hub mounting surface is toward the back or inner half of the wheel.

Before you buy, it’s good to know what you have; here is an example of the offsets on the stock RZR XP1K wheels in both inches and millimeters. Your owner’s manual or your local UTV dealer are good resources for information on stock measurements; if all else fails you can always try Google, the internet is a great resource and you’re probably not the only guy out there with these kind of questions.

2015 Polaris RZR XP 1000 stock wheel specs:

Front: 14×6 with a 5+1 or +53mm offset
Rear: 14×8 with a 6.5+1.5 or +63.5mm offset

Now that offsets are cleared up, choosing wheels should be easy, but if your still scratching your head on what kind of bolt pattern you have look no further, you can determine what your bolt pattern is by the following how to image.
