System3 UTV Tires 2025: Full Breakdown of the RR600, RX600, and SS365
I’ve been around this industry long enough to know when a company is simply releasing another SKU and when they’re making a real move. The System 3 UTV tires 2025 lineup is a move. It’s the kind of shift that comes from people who’ve spent years on the road, in the dirt, and deep in the dunes. I’ve known Mark Quintero for over thirteen years, and during the interview for this piece, I could hear the same thing I heard back when we were grinding as reps: pride, purpose, and a willingness to build products that solve problems riders face in the real world.
This year, System 3 dropped three new tires built for the machines that are rewriting the UTV horsepower game. The RR600, RX600, and SS365 aren’t small updates. They’re a full recalibration of what UTV tires need to be for platforms like the Maverick R, RZR Pro R, and Kawasaki Teryx H2. And since System 3 uses some of our Dirtbag Brands mirrors in their footage, it’s clear we both build for the same customer: riders who push machines past the polite limits.
Below is a full breakdown of each tire, how they’re built, where they shine, and why these releases matter for anyone who rides hard enough to appreciate real engineering.
Inside the Interview With Mark Quintero
When I sat down with Mark Quintero for this interview, the conversation felt less like a formal rundown and more like two veterans talking shop after years in the trenches. Mark didn’t lean on buzzwords or polished talking points. Instead, he explained how System 3 earned its reputation by doing the work that most brands skip. They traveled with reps, supported distributors on the ground, and stood shoulder-to-shoulder with the people who actually sell and ride on their products.
That kind of commitment shapes everything they build, and you can hear it when Mark talks about the RR600, RX600, and SS365. His focus on durability, predictability, and real performance isn’t marketing polish. It’s the voice of someone who has watched riders break parts, push limits, and demand more from their machines.
Mark’s perspective is backed by serious seat time—he spent ten years racing alongside Factory Can-Am/Monster Energy driver Matt Burroughs.
That decade in the pits and passenger seats of championship-winning machines (like Burroughs’ #1928 SCORE UTV) taught him exactly what fails when you push a UTV to the limit. That race-bred DNA is obvious in the new RR600; it’s built to survive the same brutal Baja miles that Mark and Matt spent years conquering.

RR600 — Race Ready Hard Terrain
If one tire sets the pace for 2025, it’s the RR600. System 3 calls it “Race Ready,” but that doesn’t fully capture how serious this tire is. The RR600 is built for riders who treat the desert like a proving ground. It targets the same high-horsepower crowd that feeds the Pro R, Maverick R, and the new Kawasaki Teryx H2.
What stands out first is the carcass. The RR600 uses System 3’s strongest 10-ply construction ever, and they didn’t just layer more material for strength. They upgraded the ply cords, added staggered sidewall belts, and built an oversized bead apex that gives the tire extreme puncture resistance without turning it into a brick. This tire flexes just enough to keep traction consistent, yet it refuses to fold under load.
One thing Mark emphasized in our interview is steering predictability. When you run high PSI in desert conditions, most tires start losing footprint. The RR600 doesn’t. It holds a wide, stable contact patch even when you’re hammering across rough terrain. That translates to smoother breakaway characteristics and a sense of control you notice within the first quarter mile.
The RR600 has also been Baja-tested for hundreds of miles. That matters, because Baja doesn’t care about marketing lines. It exposes weak compounds, overheated sidewalls, and anything that wasn’t engineered with respect. The RR600 came back from that testing cycle with its identity solidified: razor-sharp handling, real durability, and enough load capacity to serve the biggest UTVs in the game.
Sizes available:
- 33×10-15
- 35×10-15
This is the kind of tire riders combine with billet parts that stay planted at speed. It’s no surprise that some of System 3’s RR600 content includes Dirtbag Brands mirrors. Both products share the same mandate: survive the desert without drifting, rattling, or giving up when everything else starts shaking apart.

RX600 — Rally Cross Steering Precision
Where the RR600 is the desert bruiser, the RX600 is the precision tool. System 3 built this one to satisfy the riders who want rally-style speed without sacrificing stability. It uses a rally-inspired knobby tread that feels sharp on the first rotation and stays consistent as the terrain changes.
The design includes three circumferential tread voids that channel sand, gravel, and hardpack debris away from the contact patch. Additionally, the staggered horizontal grooves create controlled forward bite, giving the RX600 a calm, predictable feel when drifting or cutting lines across technical terrain.
This tire’s carcass is every bit as serious as the RR600. It’s a 10-ply rated, reinforced construction that handles the massive load of the Pro R and Maverick R without flinching. The difference is how smooth this tire feels on hardpack. During my conversation with Mark, he mentioned that the RX600 is the quietest all-terrain tire they’ve ever produced. After seeing the profile and lug layout, I believe him. Everything about the tread pattern aims at reducing noise and vibration while keeping forward grip consistent.
For riders who bounce between dunes, hardpack, fire roads, and washes, the RX600 might be the most versatile tire System 3 has released to date. It’s light enough to feel lively, strong enough to survive real punishment, and predictable enough to help drivers stay in control when the terrain changes faster than expected.
Sizes available:
- 32×10-15
- 33×10-15
- 35×10-15
- 37×10-15
Machines that run the RX600 usually demand stable components everywhere. Because of that, many riders pair these setups with billet accessories that won’t vibrate loose. It’s the same crowd running our vibration-free IronSight clamps, because speed exposes weak parts fast.

SS365 — Second-Gen Sand & Snow Evolution
A lot of companies claim to build sand tires. Few actually understand what sand demands. The SS360 became a favorite in Glamis, St. Anthony, Coos Bay, and Little Sahara because it floated, pulled hard, and didn’t punish non-turbo machines. So when System 3 announced the SS365, I wanted to know what they changed and why.
Mark didn’t hold back. The SS365 is a full second-generation redesign over the SS360, built specifically for the torque and weight of new high-horsepower platforms. Riders upgrading to the Pro R, Maverick R, and now the Kawasaki H2 know exactly why this matters. These machines will shred underbuilt sand tires, and they expose weaknesses fast. The SS365 was engineered to meet that challenge.
The rear tires are the stars of this release. At 13 inches wide, with a flatter profile and deep 22 mm paddle depth, they generate serious thrust while staying on top of the sand. The increased tread void helps the tire scoop without digging trenches. That combination gives riders the controlled wheel-speed they need when cresting bowls or powering through steep dune faces.
The front tires complement the rears with a center rib and 15 mm tread depth built for sharp directional control. Because many riders run 4WD in the dunes, System 3 engineered both the front and rear patterns to pull together. The result is smoother climbs, easier transitions, and far more predictable steering when side-hilling or dropping into technical pockets.
Additionally, the SS365 uses a lightweight 2-ply carcass that improves floatation and reduces vehicle stress. Sand riders know how quickly heavy paddles can rob acceleration or cause suspension fatigue. The SS365 avoids those problems by combining aggressive paddle geometry with low rotating mass.
Sizes available:
(From your provided chart)
- 32×11-15 (0.60 tread)
- 32×13-15 (0.85 tread)
- 33×11-15 (0.60 tread)
- 33×13-15 (0.85 tread)
- 35×11-15 (0.60 tread)
- 35×13-15 (0.85 tread)
It’s no shock that many dune riders running these tires also choose our Mirror-01 round roll bar mirrors, because visibility and vibration control matter more on sand than almost anywhere else. The dunes demand clarity and commitment. They reward products built to handle real movement, real terrain, and real horsepower.
Conversation With Mark Quintero — Real Roots in the Field
During our interview, Mark talked about something the industry tends to forget: supporting reps on the ground. Long before fancy marketing budgets and influencer content, System 3 built their reputation by showing up. They ride with reps, they traveled with distributors, and they supported Western Power Sports directly. That work created trust. Trust created momentum. Momentum created this new lineup.
When Mark said they had “really listened to enthusiasts, and the market,” it didn’t come from ego. It came from years of riding in the dirt with the same people who sell and service these products today. I’ve walked those aisles, met those dealers, and lived that pace. When a company stays rooted and keeps showing up, the results echo into the products. The RR600, RX600, and SS365 all carry that DNA.
Why These Tires Matter for Riders in 2025
The horsepower arms race isn’t slowing down. Machines like the Maverick R, Pro R, and H2 are rewriting what a “stock” UTV can do. Tires either rise to match that trend or get left behind.
System 3 chose to rise.
Each of the three 2025 releases serves a different purpose, yet they overlap in one crucial area: durability. Riders want confidence when they hit the desert at speed, climb dunes, or carve through technical terrain. They want traction that stays consistent and handling that doesn’t fall apart when the machine hits full load.
That’s why this lineup hits so hard. The tires feel like they were engineered by people who actually ride instead of committees who only look at sales charts.
Tying It Together for Real Riders
When you combine serious tires with serious components, the whole machine changes. Riders who run RR600s or RX600s usually care about stability, steering accuracy, and accessories that don’t drift or rattle. Dune riders who bolt on SS365s care about floatation, sightlines, and predictable control when the terrain can change instantly.
As someone who has built Dirtbag Brands from the ground up, I see the crossover clearly. Our mirrors show up in System 3’s footage for a reason. We both design for the same rider: the one who refuses to settle for equipment that breaks down when the terrain gets real.
