HOW POLARIS MEASURES "VEHICLE WIDTH"

Own a Polaris Xpedition or thinking about picking one up soon, and you're trying to wrap your head around stock width vs adding custom wheels and tires? We put together this fitment guide to ensure you know exactly what your stock Polaris Xpedition wheels are, and what you can expect if you increase or decrease your OEM offset/backspacing.

FACT: When you see a vehicle width measurement on the Polaris website for any model, it is crucial to understand where that measurement is taken. When you see a width of 64" for the Polaris Xpedition, Polaris is specifically measuring from the driver's side hub to the passenger's side hub, NOT tire sidewall to tire sidewall. This measurement does not account for wheel thickness/width, and, more importantly, tire width. All added up, your stock wheels and tires actually increase the total width by over three inches compared to Polaris' hub-to-hub measurement, making your overall Xpedition vehicle width 67" straight from the factory.

2026 Polaris Xpedition Specs

The Polaris XPEDITION is a specialized "adventure" side-by-side (SxS) designed for overlanding and multi-day backcountry trips. Introduced in 2023, it combines the all-terrain performance of a sport SxS with the comfort, cargo capacity, and climate-controlled environment typically found in pickup trucks or SUVs. Use the width table below to determine your preferred wheel offset.

Engine: Powered by a 999cc ProStar 1000 Gen 2 parallel-twin engine producing 114 horsepower.
Performance: Features a 200+ mile fuel range and 2,000 lb towing capacity.
Suspension: Equipped with FOX 2.0/2.5 Podium QS3 shocks providing 14–15 inches of travel and 14 inches of ground clearance.

WHAT IS A WHEEL HUB

A wheel hub is the central component connecting your vehicle's wheel to the axle and suspension, allowing the wheel to rotate freely while supporting the vehicle's weight. The hub features studs for attaching the wheel. The Xpedition has a 5x114.3 bolt pattern (PCD), meaning the hub has five studs that correspond to the five lug holes on your wheels.

Why specific measurement matters

Factoring overall vehicle width is a decades-old battle. Polaris measures hub-to-hub for stock vehicle width, while other manufacturers measure the actual overall vehicle width (sidewall to sidewall). This confuses plenty of people in the offroad industry, particularly those who already own a toy trailer or plan to store their UTV in a garage with limited space.

Let's dive into the factors, variables, and scenarios that make measuring overall vehicle width a mess:

Measuring vehicle width under load compresses the suspension, pushing the wheels and tires outward, away from the vehicle. Consider your width measurement before and after lifting the UTV off the ground with a shop lift. Ever notice how tall your vehicle is after a tire rotation? That's because the suspension is not compressed to real-world operation.
Modifying your suspension or hub assembly can drastically affect your overall width.
Adding sprung weight to your vehicle can affect the width measurement. (lightbars, armor, skid plates, etc)
Increasing or decreasing wheel offset/backspacing will affect your vehicle's width.

What is OFFSET VS BACKSPACING?

Wheel offset measures the distance from the wheel's centerline to its mounting surface, while backspacing measures the distance from the mounting surface to the back edge of the wheel. Both determine how a wheel fits on a vehicle, but offset is more precise because it is measured in millimeters (mm). Offset can be positive or negative. In contrast, backspacing is measured in inches and is always a positive number. A positive offset, or greater backspacing, pushes the wheel further inward, closer to the suspension, while a negative offset, or smaller backspacing, pushes the wheel outward, away from the vehicle.

WHEEL OFFSET COMPARISON

The background image illustrates how changing your wheel's offset can significantly affect your UTV's width. The Xpedition on the left features the V16 15x7 +35mm. The Xpedition on the right features the V16 15x8 -12mm (4+4) wheel. Notice how much more of the hub is sucked into the wheel on the left in comparison to the wheel on the right. A low or even negative offset pushes your wheels out from your vehicle, giving you an aggressive, wide stance.
