what size are stock rzr wheels?

MaintenanceGary PhillipsJun 28, 2026, 11:54 AM20 replies

I just picked up a used 2018 RZR 900 and the tires are shot. I'm trying to figure out what size the stock wheels are so I can order replacements without messing up the offset or bolt pattern. I've seen conflicting info online—some say 12-inch, others 14-inch. Can anyone confirm the exact specs for this model? I'm mostly trail riding, so I don't want to go too aggressive, but I need something reliable.

Stock RZR 900 wheels are 12x7 with a 4/156 bolt pattern and 4+3 offset. That's what came on mine from the factory. Double-check your year because some early models had different offsets.

I've got a 2016 RZR 900 and mine are 12-inch too. The offset is what matters most—too much and you'll rub. Stick with OEM specs unless you're lifting it.

Actually, I think the 2018 RZR 900 uses 14-inch wheels on some trims. My buddy's 2018 XP 1000 has 14s. You sure you don't have the XP? Check your VIN or call a dealer.

The 900 is definitely 12-inch. I've replaced mine twice. The bolt pattern is 4x156, and the backspacing is 4+3. Don't trust random forums—measure your current wheels to be safe.

I run aftermarket 14s on my 2015 RZR 900, but I had to add spacers to clear the calipers. If you're staying stock, 12s are fine and cheaper. Just get good tires.

You can fit 14s if you want, but the stock wheels are 12x7. The ride height changes slightly, and you'll need to adjust tire pressure. I'd stick with 12s for trails.

Before you buy anything, confirm the year. Polaris changed specs around 2017. My 2019 RZR 900 has 12s, but I've seen 2018s with 14s if they're the Trail model.

I disagree with the guy saying 14s are stock. I have a 2018 RZR 900 S and it came with 12s. The XP models have 14s. Don't mix them up or your speedo will be off.

The offset is 4+3 on stock 12s. If you go with a different offset, you might need wheel spacers or lift kit. I learned that the hard way after rubbing on the sway bar.

I'd recommend checking the tire size on the sidewall of your current tires. It should say something like 27x9-12 or 27x11-12. That'll tell you the wheel diameter.

For trails, stock 12s are great because they have more sidewall flex for comfort. 14s look better but ride stiffer. I switched back to 12s after a season on 14s.

Make sure the bolt pattern is 4x156. Some aftermarket wheels are 4x137 and won't fit without adapters. I almost bought the wrong ones last month.

Jordan SimmonsJun 28, 2026, 11:55 AM

If you're buying used wheels, check for bent rims or cracks. Stock 12s are pretty durable but can bend on rocks. I've had to replace two after hard rides.

Steven BryantJun 28, 2026, 11:55 AM

I run 12s with 28-inch tires and no lift. They clear fine on my 2017 RZR 900. Just watch the offset—too much positive offset will hit the frame at full turn.

Lucas MitchellJun 28, 2026, 11:55 AM

The stock wheels are steel on some models and aluminum on others. Steel are heavier but cheaper to replace. Aluminum are lighter but can crack. Depends on your budget.

Samuel CarterJun 28, 2026, 11:55 AM

I've seen people run 14s from a Polaris General on their RZR 900. They fit with minor trimming. But honestly, just get 12s to avoid headaches.

Bradley ParkerJun 28, 2026, 11:55 AM

Don't forget the lug nuts. Stock wheels use a specific taper. Aftermarket wheels might need different ones. I had to buy new lugs when I switched to Method wheels.

Kyle RussellJun 28, 2026, 11:55 AM

I'd caution against going too wide with tires on stock 12s. A 9-inch wide tire is fine, but 11-inch can rub on the rear trailing arms. Stick with 27x9-12 front and 27x11-12 rear.

Dan WalkerJun 28, 2026, 11:55 AM

If you're only doing trails, the stock 12s are fine. I've got 30,000 miles on mine with no issues. Just replace the tires when they wear out.

Patrick LongJun 28, 2026, 11:55 AM

One more thing—check your wheel bearings while you're at it. Worn bearings can cause vibration that feels like wheel imbalance. I replaced mine and it fixed the wobble.
