Buyer's Guide: Factory Specs For The Polaris RZR Tire Size, Wheel Size, Wheel Offset, And Bolt Pattern

Nov 14th 2020

For first-time UTV owners, the amount of information there is to learn about Polaris RZR tires and wheels can seem overwhelming at first. Even experienced riders may not hold all there is to know about RZR tires and rims in the forefront of their minds at all times. But regardless of the particular Polaris RZR year and edition that you own, be it an RZR Turbo, RZR Pro, RZR XP, or anything else, there are a few Polaris RZR stock tire and wheel specs that you should know when making considerations about adjusting, augmenting, or modifying your machine. Furthermore, if you’re simply looking into replacement factory RZR tires / wheels, a spare tire for your RZR, or stock-style Polaris RZR lug nuts, knowing the pertinent details about your side-by-side will save you from getting the wrong parts, replacements, and aftermarket upgrades!  

Stock Rim Bolt Pattern For The Polaris RZR Lineup

Aside from the youth-size Polaris RZR 170 — which has a bolt pattern of 4/110 — all other Polaris RZR editions have a wheel bolt pattern of 4/156. This includes both the Polaris RZR 1000 and RZR 4 1000, as well as the RZR XP Turbo, the RZR Pro XP, and the 800, 900, and 570 RZR models. Even the one-seater Polaris RS1 uses a 4/156 bolt pattern, which greatly simplifies things with consistency across almost all Razor vehicles. While you can use wheel adapters to fit non-conforming rims onto your RZR, with so many options available, why would you?

Stock Lug Nut Specs For The Polaris RZR Lineup

There are two main variations of stock lug nut sizes that Polaris uses for its RZR-branded side-by-sides — with the RZR 170 again being the outlier and using 10mm x 1.25 lug nuts. Vehicles like the Polaris RZR 1000, Polaris RZR Turbo, and Polaris RS1 have stock lug nuts that measure 12mm x 1.5, while vehicles such as the 2011-2014 Polaris RZR 900 and RZR 4 900 as well as the RZR 800, RZR S 800 and RZR 570 have stock lug nuts that measure 3/8” x 24 — with the latter number indicating that there are 24 threads for every inch of length. 

If you’re running aftermarket rims, you will likely need to use thin-wall lug nuts or spline-drive lug nuts, because even if the lugs themselves fit through the rims, you might not be able to fit a socket around them to ensure proper tightness. 

Stock Tire And Wheel Sizes For The Polar RZR Lineup

The Polaris RZR 1000, Polaris RZR 4 1000, Polaris RS1, and Polaris RZR XP Turbo all come stock with the same size tires and wheels, which measure 29x9-14 in the front and 29-11-14 in the rear. The first number set is the diameter and width of the tire -- measured in inches -- and the second number is the diameter of the rim. For the 2011-2014 Polaris RZR 900 and four-door RZR 900, the stock tire and rim size is 27x9-12 in the front, and 27x11-12 in the rear — although some models come stock with wider 27x12-12 rear tires. 

As one might expect, the stock Polaris RZR tire and rim size gets smaller as you progress downward on the horsepower scale. The Polaris RZR 800 and 800 S come with 26x9-12 front tires and wheels, and 26x12-12 rear tires and wheels (however some models have 27” stock tires). Moving down the CC ladder even further, the Polaris RZR 570 comes stock with 25x8-12 fronts and 25x10-12 rears, while the youth-size RZR 170 has 19x7-8 front rims and tires with 20x10-9 rear rims and tires.  

When comparing stock Polaris RZR tire and wheel sizes to those of aftermarket RZR tires and wheels, it should be noted that some run slightly smaller in diameter, while others run true to size. A set of 28” Roctane tires, for example, will be noticeably taller than a set of 29” Bighorn tires, whereas a set of aired-down 30” Terrabite tires will measure in at around 28-3/4” at 12psi.

Stock Wheel Offset For The Polaris RZR Lineup

The factory Polaris RZR rims measure at 5.44 + 0.56, giving them a stock offset of 6+1 or 5+2. The offset your Polaris RZR wheels have is the length from the mounting surface on the hub to the centerline of the wheel. The hub mounting surface on rims with no offset are flush with the wheel’s centerline, whereas wheels with a negative offset are extended further outward, and wheels with a positive offset are positioned further inward underneath the vehicle.  

If you’re considering Polaris RZR wheels with non-stock offsets or backspacing, remember that when you alter the offset, you also change the inclination of the king pin, which will affect the handling of your UTV. A 4+3 offset, for example, will give you a lot of feedback through the steering wheel, making your steering system feel heavier. A 4+3 wheel offset will also put more stress on the steering components and wheel bearings. Because of this, we’d suggest sticking as close to stock as possible. After all, there’s a reason why Polaris chose to use the backspacing that they do!

Closing Remarks

A large number of riders choose to deviate from Polaris RZR stock tire and wheel specs. And with accessories like wheel spacers, lift kits, rim adapters, and forward a-arms, the ability to alter the size and style of your Polaris RZR tires and wheels has become increasingly easy to do. We’re not suggesting that swapping out your stock tires and rims is a bad idea, but rather, we are simply recommending that you do a bit of research before altering your stock Polaris RZR tires and wheels!
