Maxxis
The Roxxzilla is the tire Kyle Chaney ran when he became the first side-by-side driver to win the 4400 class at King of the Hammers. That is not marketing. That is a race result, and it is the shortest possible answer to why Maxxis is the default tire brand in the UTV aftermarket.
Maxxis builds nineteen distinct UTV and side-by-side tires, and they are genuinely different products rather than one casing with different tread stamped on it. Roxxzilla for rock, in a standard compound and a stickier competition compound. Bighorn, Bighorn 2.0, Bighorn 3.0 and Bighorn Radial for all-terrain, each a different construction. Carnivore and Rampage for light-truck-inspired 8-ply durability. Zilla, Maxxzilla, Maxxzilla Plus and Mudzilla for mud. Ceros and Liberty for hardpack and racing. Coronado and Workzone for utility work.
We stock the Maxxis UTV lineup in 11, 12, 14 and 15-inch fitments for Polaris Ranger and RZR, Can-Am Defender and Maverick, Honda Talon and Pioneer, Kawasaki Teryx and KRX, Yamaha Wolverine and YXZ, CFMOTO UForce and ZForce, and more. Tire buying goes wrong in specific and predictable ways: wrong rim width for the section width, a diameter your clutching cannot pull, a front and rear size mismatch on a machine that needs matched rolling diameter. We are the fitment experts on this. Call us at (414) 219-0509 Monday through Friday, 8am to 6pm Central, or Saturday 9am to 3pm. Text us at (920) 644-5280.

BUYER'S GUIDE: How to Choose Maxxis UTV Tires
Maxxis makes more UTV tires than anyone, which is a good problem right up until you have to pick one. Five of them have "zilla" in the name. Four of them are called Bighorn.

Every Maxxis Tire With "Zilla" In The Name, Explained
Five tires, one suffix, four completely different jobs. This is the single most common source of confusion on this brand.
| Tire | What it actually is | Terrain |
|---|---|---|
| Zilla | The lightweight one. Mud-slinging tread that still rides smoothly on the way to the mud | Mud plus trail |
| Maxxzilla | Deeper, more aggressive lugs than the Zilla | Serious mud |
| Maxxzilla Plus | The most aggressive of the mud Zillas | Deep mud |
| Mudzilla | Dedicated mud tire, the classic paddle-style bite | Mud only |
| Roxxzilla | Not a mud tire at all. 8-ply rock-crawling radial | Rock and desert |
The one to burn into memory: Roxxzilla is a rock tire. The name follows the Zilla family, the purpose does not. If you buy a Roxxzilla expecting mud performance you will be disappointed, and if you buy a Maxxzilla for rock crawling you will tear lugs.
Every Maxxis Tire Called "Bighorn," Explained
Four Bighorns, and they are not trim levels of each other.
| Tire | What changed | Best for |
|---|---|---|
| Bighorn Radial | The original. Non-directional tread, radial construction, 6-ply-rated | All-terrain riders who want the proven one |
| Bighorn 2.0 | Same tread pattern with slimmer lugs and lighter weight. The lightest, most versatile racing tire in the Bighorn family | XC and off-road racing. Tire of choice for champions Hunter Miller and Kyle Chaney |
| Bighorn 3.0 | The current-generation all-terrain Bighorn, 6-ply radial. 25/32" tread, front and rear specific, 26" to 29" | General all-terrain riding |
| Bighorn (bias) | The non-radial version still found in some sizes | Budget-conscious replacement |
How to choose between them. If you race or want the lightest rotating mass, Bighorn 2.0. If you want the all-around trail tire most Bighorn buyers actually want, look at Bighorn 3.0 or the Radial. Unsprung rotating weight matters more on a UTV than most people expect, and it is the entire reason the 2.0 exists.
Roxxzilla: The Rock-Crawling Spec Sheet
The Roxxzilla is the most searched tire in the Maxxis UTV line, and it earns it. Here is the complete size and spec run straight from Maxxis.
Why it wins on rock
- 8-ply-rated radial construction. Sidewall strength for airing down and for sharp rock edges.
- Two compounds. Sizes marked with an asterisk in Maxxis part numbers are the competition sticky compound. Unmarked is standard. Sticky grips harder and wears faster. Standard lasts longer and still climbs.
- Race-proven. Tire of choice for Kyle Chaney, the 2025 King of the Hammers 4400 class champion, and the first side-by-side to win that class outright.

Asterisk denotes competition sticky compound.
Shop the Roxxzilla in 14-inch once you have your size, or call us and we will confirm it against your machine.
Two things riders miss on this chart. First, the 35-inch sizes measure 34.5 inches, not 35, which matters when you are calculating clearance against a lift. Second, max pressure is only 18 PSI across the entire line. This is a low-pressure tire by design. Overinflating a Roxxzilla defeats the compound and the carcass flex that make it work.
Understanding Ply Rating, Radial Construction and Tread Depth
Three specs decide most of what a tire will do, and they trade against each other.
Ply rating
6-ply-rated tires are lighter and ride softer. Less rotating mass means better acceleration and less strain on your clutch and belt. Bighorn 2.0, Bighorn 3.0, Ceros, Zilla and the Maxxzillas are 6-ply.
8-ply-rated tires resist punctures and cuts far better and carry more load. They also weigh more and ride stiffer. Roxxzilla, Carnivore, Rampage, Liberty and Coronado are 8-ply.
The honest tradeoff: 8-ply is the right answer for rock, roots, desert and heavily loaded utility machines. 6-ply is the right answer for trail riding, racing and anywhere clutch life and ride quality matter more than puncture resistance. Buying 8-ply for a stock trail machine adds weight you will feel and puncture protection you may never need.
Radial versus bias
Radial casings flex more independently from the tread, which means a bigger contact patch, better ride quality and better heat management at speed. Most of the current Maxxis UTV line is radial. Bias-ply tires are stiffer and typically cheaper, and they still have a place on lower-speed utility machines.
Tread depth, and why the rock tire has less of it
This one surprises people. Bighorn 2.0 runs 23/32 to 25/32 inch of tread depth, and Bighorn 3.0 runs 25/32 inch. Roxxzilla runs 19/32 inch. The rock tire has shallower tread than the all-terrain tire.
That is deliberate. Deep lugs flex and squirm on rock, and flex is exactly what you do not want when you are trying to hold a line on a ledge. Rock tires get grip from compound and casing, not from lug depth. Mud tires get grip from lug depth, because they need to dig and clean out. Depth is not a quality measure. It is a terrain measure.
Sizing a Maxxis Tire Without Breaking Your Machine
Match the rim width to the section width. Maxxis publishes a recommended rim size for every tire. A 14x7.0 recommendation on a 30x10.00R14 is not a suggestion. Mounting a wide tire on a narrow rim balloons the sidewall and hurts stability.
Watch the diameter jump. Going from a 28-inch OEM tire to a 32-inch Roxxzilla is a four-inch increase, and that changes effective gearing at the wheel. Expect slower acceleration, more belt heat and more strain on the clutch. Above roughly 30 inches on most machines, a clutch kit or gear reduction stops being optional.
Check front and rear sizing. Many Maxxis sizes are position-specific. Bighorn 3.0 is explicitly front and rear specific, and Bighorn 2.0 lists distinct front and rear sizes with different section widths in the same diameter. Running the wrong one front to rear can bind the drivetrain on machines with tight rolling-diameter tolerance.
Confirm clearance. Section width plus a lift kit does not always equal fitment. Fender flares, A-arm geometry and steering lock all get involved.
From the shop: the single most common tire return we process is a size that fits the wheel but not the machine. Rim width and bolt pattern are the easy part. Turning radius at full lock with a 32-inch tire and a two-inch lift is the part people find out about in the driveway. Send us your year, model, wheel size, lift and where you ride, and we will tell you the largest tire that actually works.
Maxxis UTV Tire Pricing
Tire pricing is per-tire unless a listing states otherwise, and a set is four. That math catches people, so plan for it.
The value end, roughly $140 to $200 per tire. Mudzilla and Zilla in smaller diameters, Bighorn 2.0 in 11 and 12-inch fitments. Real Maxxis construction at the size where a UTV tire costs the least.
The core of the range, roughly $190 to $300 per tire. This is where most Maxxis buyers land: Bighorn 2.0, Bighorn 3.0 at $213 to $294, Bighorn Radial, Ceros, Carnivore at $274 to $311, Coronado, Maxxzilla and Maxxzilla Plus in common 12 and 14-inch sizes. Full radial construction and the tread pattern you actually want for your terrain.
The premium end, roughly $300 to $415 per tire. Roxxzilla, Liberty, Rampage and the largest Carnivore and Bighorn Radial sizes. Eight-ply rock and race construction in 14 and 15-inch fitments, and the sticky-compound Roxxzillas.
Free shipping applies on orders over $250, which a set of four clears in every case. Affirm financing is available at checkout, which is worth knowing when a set of Roxxzillas runs past a thousand dollars. Our Best Price Guarantee means if you find the same tire cheaper, we will match it.
About Maxxis
Maxxis is the powersports tire brand you see on more UTVs than any other, and the company behind it is considerably bigger than the UTV category. Maxxis International builds tires for automotive and light truck, bicycle, motorcycle, ATV and side-by-side, kart, trailer, lawn and garden, and industrial equipment. The UTV lineup sits inside a company with genuine scale in rubber compounding and casing design, which is a large part of why a Maxxis UTV tire holds up.
Racing is the proof. Maxxis runs contingency programs across ATV, side-by-side and moto, and sponsors athletes including King of the Hammers 4400 champion Kyle Chaney and Hunter Miller. When the Roxxzilla page says it is the best rock-crawling tire on the market, there is a race result behind the claim.
OEM fitment is the other proof. Polaris specifies the Rampage Fury as original equipment on the RZR Pro R and Turbo R. Yamaha specifies the Carnage on the YXZ 1000R SS XT-R. Honda uses the MU9H on the Talon. Polaris uses the MU511 and MU521 on select Ranger models. Machine manufacturers do not hand a tire contract to a brand that warranties poorly.
Maxxis publishes a full powersports catalog and an ATV/SxS OEM fitment guide on their own site, and tire registration and warranty details run through Maxxis directly.

Maxxis UTV Tire FAQ
What is the best Maxxis tire for rock crawling? The Roxxzilla. It is 8-ply-rated radial, available in standard and competition sticky compound, and it was the tire on Kyle Chaney's machine when he became the first side-by-side driver to win the 4400 class at King of the Hammers. Sizes run 30, 32, 35 and 37-inch across 14, 15 and 17-inch rims.
What is the difference between Roxxzilla standard and competition compound? Compound only. The competition version, marked with an asterisk in the Maxxis part number, uses a softer sticky rubber that grips rock harder and wears faster. Standard compound lasts longer on mixed terrain. If your machine sees trail miles between rock sections, buy standard. If it is a dedicated crawler, buy sticky.
Is the Roxxzilla a mud tire? No. Despite the Zilla name it is a rock and desert tire. For mud, look at Zilla, Maxxzilla, Maxxzilla Plus or Mudzilla.
What is the difference between Bighorn 2.0 and Bighorn 3.0? Bighorn 2.0 is the lightweight racing-oriented version, with the original tread pattern reworked with slimmer lugs. Maxxis calls it the lightest and most versatile racing tire in the Bighorn family. Bighorn 3.0 is the current-generation all-terrain Bighorn, with 25/32-inch tread depth and front and rear specific sizing from 26 to 29 inches. Both are 6-ply-rated radials. Race or minimize rotating weight, buy 2.0. General trail riding, look at 3.0.
Are Maxxis tires 6-ply or 8-ply? Both, depending on the model. Bighorn 2.0, Bighorn 3.0, Ceros, Zilla and the Maxxzillas are 6-ply-rated. Roxxzilla, Carnivore, Rampage, Liberty and Coronado are 8-ply-rated. Six-ply is lighter and easier on your belt and clutch. Eight-ply resists punctures better and carries more load.
Do I need a clutch kit with bigger Maxxis tires? Usually yes, past about 30 inches on most machines. A larger tire changes effective gearing at the wheel, which means more belt heat, slower acceleration and more clutch strain. Going from a 28-inch OEM tire to a 32-inch Roxxzilla is a significant jump. Tell us your machine and target size and we will tell you honestly whether you need clutching.
What pressure should I run in Maxxis UTV tires? Check the max PSI stamped on your specific size, because it varies widely across the line. Roxxzilla is rated to a maximum of 18 PSI in every size. Some Bighorn 2.0 sizes are rated as low as 7 PSI and others as high as 32. Max PSI is a ceiling, not a target. Most riders run well below it, and rock crawlers run lower still.
Why does the rock tire have less tread depth than the trail tire? Because deep lugs flex on rock, and flex costs you grip and precision. Roxxzilla runs 19/32 inch. Bighorn 2.0 runs up to 25/32 inch. Rock tires get grip from compound and casing. Mud tires get it from lug depth. Deeper is not better, it is different.
Does a 35-inch Maxxis tire actually measure 35 inches? Not exactly. The 35x10.00R14 and 35x10.00R15 Roxxzillas both measure 34.5 inches overall diameter. Use the published diameter rather than the size name when you are calculating clearance.
Are Maxxis tires original equipment on any UTVs? Yes, on several. The Rampage Fury ships on the Polaris RZR Pro R and Turbo R, the Carnage on the Yamaha YXZ 1000R SS XT-R, the MU9H on the Honda Talon, and the MU511 and MU521 on select Polaris Ranger models.
Do Maxxis UTV tires come with a warranty? Maxxis handles powersports tire warranty directly and publishes terms and a tire registration process on their own site. Our own 90-day return policy applies to unused tires, and mounted tire-and-wheel sets carry their own terms. Call us before mounting if you have any doubt about fitment, because a mounted tire is no longer returnable.
