Premium 33-Inch UTV Tires for 15-Inch Wheels

Upgrade your SxS with the ultimate performance boost. Our curated collection of 33-inch UTV tires is engineered for riders who refuse to compromise on ground clearance, traction, or trail durability. Whether you’re piloting a Polaris RZR Pro R, Can-Am Maverick X3, or Kawasaki KRX 1000, stepping up to a 33" diameter is the single best way to conquer deeper ruts, scale steeper rock faces, and dominate the desert.

Choosing the Right Fitment: 33x10R15 vs 33x9.5R15

33x10R15: The "Gold Standard"

The 10-inch wide tire is the industry favorite for maximum stability. By providing a larger contact patch, this size offers superior footprint for technical rock crawling and predictable tracking across high-speed desert floors. It is the go-to choice for riders wanting a planted, aggressive feel on all terrains.

33x9.5R15: The "Skinny" Racer

Preferred by competitive racers and trail enthusiasts looking to reduce rotating mass. The 9.5-inch width saves precious horsepower, reduces stress on your drivetrain, and provides laser-sharp steering response in tight, technical wooded trails. It’s the ultimate choice for agility and weight savings.

Frequently Asked Questions: 33" UTV Tires

What is the difference between 33x10R15 and 33x9.5R15?
The primary difference is the width and weight. A 33x10R15 tire provides a larger contact patch, offering better stability in rocks and high-speed desert sections. The 33x9.5R15 "skinny" tire is lighter (saving 2-5 lbs), which reduces rotating mass for faster acceleration and provides more precise steering response in tight trails.
Do I need a clutch kit for 33-inch UTV tires?
For most 1000cc+ machines (like the RZR XP or Maverick X3), a 33-inch tire is a manageable upgrade. However, to preserve your belt life and regain low-end "grunt" lost to the larger diameter, a clutch kit or gear reduction is highly recommended, especially for technical rock crawling or heavy mud.
Will 33" tires rub on my stock UTV?
On modern "Wide" machines like the RZR Pro R, Turbo R, and Kawasaki KRX 1000, 33-inch tires usually fit with zero modifications. For older models or 64-inch wide machines, you may experience slight rubbing at full steering lock; this can often be solved with a small lift or high-clearance A-arms.
Are these 33-inch SxS tires DOT approved?
No, they are not. Due to Federal NHTSA laws, tires designed for off road use are not allowed to be marked "DOT". However, there are a good number of tires that are manufactured to DOT standards and use Segmented Mold, Steel Belted Radial construction. See our Premium Automotive Grade UTV Tire Collection to browse these options. These include models from Kenda, Federal, Broad Peak, XComp, Atturo, Dragonfire, Valor, and Obor. Always check the specific sidewall markings for DOT certification.
What is the best ply rating for 33" rock crawling tires?
For sharp rocks and jagged terrain, we recommend an 8-ply or 10-ply radial construction. Tires like the BFGoodrich KM3 or System 3 XCR350 offer reinforced sidewalls that resist pinch flats and punctures far better than standard 6-ply OEM tires.
