Tusk
The Tusk Terrabite is an 8-ply radial with three-quarters of an inch of tread and a truck-style pattern, and it is the reason most riders find this brand in the first place. It rides quietly on hard pack, holds up under a loaded machine, and costs less than the premium tires it gets compared to.
If you have been searching for both Tusk and Rocky Mountain ATV and wondering whether they are the same thing: they are connected. Tusk is the house brand, Rocky Mountain ATV/MC is the company behind it, and riders use the two names interchangeably. Search either one and you are looking for the same parts.
We stock the UTV side of the Tusk catalog in depth: Terrabite and Megabite tires, Tusk wheels and beadlocks, windshields in clear, smoked and glass, aluminum roofs, Barrier doors, axles, spare tire carriers, universal tool and repair kits, skid plates, lighting, turn signal kits and light bars. Tusk also builds a large dirt bike and street catalog. We focus on what fits a side-by-side.
Fitment on this brand splits in ways that catch people: tire sizes vary by machine and by trim, wheel bolt patterns are not interchangeable, and windshield mounting differs by cage profile. We are the fitment experts here. Call us at (414) 219-0509 Monday through Friday, 8am to 6pm Central, or Saturday 9am to 3pm. Text us at (920) 644-5280. Tell us your year, model and current tire size and we will match it before you order.

BUYER'S GUIDE: Tusk / Rocky Mountain ATV (UTV) Parts and Accessories
Tusk covers most of a UTV, so this guide is ordered the way people actually buy: tires first, then wheels, then the cab, then the hard parts and the smaller upgrades.
Tusk and Rocky Mountain ATV: What the Relationship Actually Is
Worth clearing up, because the naming confuses a lot of buyers.
Tusk is a house brand. It is developed and sold by Rocky Mountain ATV/MC, a powersports company based in Payson, Utah. Where most aftermarket brands are independent manufacturers selling through many retailers, Tusk exists as one company's own line.
Riders use both names for the same thing. Someone might say they run "Tusk Terrabites" or "the Rocky Mountain tires." Both refer to the same product. If you searched either term to get here, you are in the right place.
What that means practically. House brands cut out a layer of margin, which is why Tusk pricing tends to sit below independent brands offering comparable construction. The Terrabite is the clearest example: 8-ply radial construction at a price point where a lot of competing tires are 6-ply.
Tusk Terrabite: The Tire That Built the Brand
The Terrabite is Tusk's flagship, the most-searched product in the line, and our best-selling Tusk item. It carries over 1,300 customer ratings averaging 4.8 out of 5, which is a larger review base than most UTV tires accumulate. Here is what it actually is.
Construction and specs
| Spec | Detail |
|---|---|
| Construction | Radial, 8-ply rated |
| Tread depth | 3/4 inch |
| Tread pattern | Truck-style, non-directional |
| Terrain rating | Medium to hard |
| Load rating | Up to 1,000 lb at 22 PSI, varies by size |
| Shoulder | Aggressive shoulder and sidewall tread for protection and bite |
| Sizes | 24 sizes across 12", 14", 15" and 16" rims, from 25x8-12 to 35x10-16 |
Available sizes by rim diameter:
- 12": 25x8-12, 25x10-12, 27x9-12, 27x11-12
- 14": 26x9-14, 26x11-14, 27x9-14, 27x11-14, 28x10-14, 29x9-14, 29x11-14, 30x10-14, 31x10-14, 32x10-14, 33x10-14
- 15": 28x10-15, 30x10-15, 31x10-15, 32x10-15, 33x10-15, 34x10-15, 35x10.5-15
- 16": 32x10-16, 35x10-16
That is genuinely broad coverage, and it is part of why this tire shows up on so many different machines. Twenty-four sizes means most riders can stay stock-size or step up without changing wheels.
Weight by size, and why it matters
| Size | Weight |
|---|---|
| 27x9.00-12 | 28.3 lb |
| 32x10.00-14 | 39.6 lb |
| 32x10.00-15 | 39.8 lb |
Going from a 27 to a 32 adds roughly 11 pounds per corner. That is 44 pounds of rotating mass on the machine, and your clutch and belt will feel it. Above about 30 inches on most machines, a clutch kit stops being optional.
One thing worth saying plainly about pressure. The 1,000 lb load rating is quoted at 22 PSI, and that number is a maximum, not a recommendation. Running 22 PSI on a trail machine gives you a harsh ride and a small contact patch. Check your owner's manual for the recommended pressure and treat the sidewall number as a ceiling.
Where the Terrabite is the right buy, and where it is not
Right buy: hard pack, gravel, ranch and desert riding, loaded utility machines, hunting rigs, anyone who wants one tire that does most things and lasts. The truck-style tread is quiet on hard surfaces and the 8-ply carcass handles weight.
Wrong buy: deep mud. The Terrabite is a medium-to-hard terrain tire. Its tread is designed to hold a surface, not to dig and clean out. For mud, look at the Megabite.
Terrabite, Aramid Terrabite and Megabite: Which One
Three names, and the difference is not obvious from a product title.
| Tire | Construction | Built for |
|---|---|---|
| Terrabite | 8-ply radial, 3/4" tread | All-terrain. Hard pack, gravel, desert, ranch. The default |
| Aramid Terrabite | 10-ply rated | The same tread mission with a heavier-duty carcass. For loaded machines and sharp terrain where sidewall punctures are the problem |
| Megabite | Radial | Mud and soft terrain. The aggressive-tread option |
How to pick. Most riders want the standard Terrabite. Step up to the Aramid version if you are running a heavy utility machine, hauling regularly, or riding sharp rock where you have punctured tires before. Choose the Megabite if mud is the reason you are shopping, not an occasional condition.
From the shop: the most common Tusk tire mistake we see is a Terrabite bought for a mud machine. It is a genuinely excellent tire and it will disappoint anyone who spends weekends in bottomless holes. Tell us where you ride and we will point you at the right one, even when that means the cheaper tire.
Tusk Wheels
Tusk builds wheels to pair with their tires, including beadlock options. The specs that decide fitment are the same on any brand:
Bolt pattern. Four-lug patterns like 4x137 and 4x156 are not interchangeable. This is the most common wheel-fitment error we see.
Offset and backspacing. Offset determines where the wheel sits relative to the hub. More offset pushes the wheel out, widening your stance and adding leverage on bearings and CV joints. Less offset tucks it in and can rub at full steering lock.
Load rating. Utility machines that haul and tow need the rating checked, not assumed.
Beadlocks. A beadlock clamps the tire bead mechanically so you can run low pressure without unseating a bead. Rock crawlers and low-pressure riders want them. Most trail and utility riders do not need one, and they add cost plus a ring of bolts that must be torqued evenly to spec.
Tusk also sells tire and wheel packages mounted and ready to bolt on, which removes the mounting cost and the risk of a mismatch between rim width and section width.
Tusk Windshields: Clear, Smoked and Glass
Three material choices, three different jobs.
Clear polycarbonate. Maximum visibility, lightest, best impact resistance. The default for most riders. Polycarbonate scratches more easily than glass, which is the tradeoff.
Smoked polycarbonate. Same impact resistance with tint. Cuts glare and low sun, and hides cab clutter. Worth knowing that smoke reduces light transmission at dusk and at night, which matters if you ride after dark.
Glass. Best scratch resistance by a wide margin, and the only option that supports a proper wiper. Heavier, so plan on two people for installation, and it is the one material that will crack rather than flex under a hard branch strike.
Full, half and flip. Full windshields seal the cab for cold and dust. Half windshields divert air over your head while keeping the open-cab feel. Flip and vented designs give you both from the driver's seat, which is the right answer for anyone riding across seasons in the upper Midwest.
Tusk Roofs and Doors
Roofs. Tusk aluminum roofs are laser-cut and black powder coated, with anti-vibration gaskets at the mounting points. The gasket detail matters more than it sounds: an aluminum roof bolted directly to a cage drums and rattles at speed, and the gasket is what keeps a metal roof from being louder than a plastic one.
Barrier doors. Built on a solid steel frame with aluminum door skins. Steel frame means the door holds its shape and latches consistently over time, which is where cheaper doors fail. Aluminum skins keep the weight down.
Full doors close the cab for cold and dust. Half doors keep mud and brush out while leaving the cab open.
Tusk Axles
Axles are a wear item on any machine that sees real use, and they are where an OEM replacement gets expensive fast. Tusk axles are direct-fit replacements, which means no modification and no guesswork on length.
Two things to check before ordering: your machine's trim, because axle length varies within the same model year across trims on several Polaris and Can-Am platforms, and whether your machine is lifted, because a lift changes the operating angle and a taller lift may call for a heavier-duty axle than stock.
From the shop: boots are the most common failure point on any axle, from any brand. A torn boot slings out the grease, dirt gets into the CV, and the joint fails weeks later. Check boots at the same interval you check tire pressure, and replace a torn one immediately rather than waiting for the noise.
Tusk Tire Carriers, Tool Kits and Skid Plates
Spare tire carriers. The accessory riders skip until the first time they are three miles out with a flat. A carrier that mounts to the bed or cage keeps the spare secure and out of your cargo space.
Universal tool and repair kits. Tusk builds compact kits designed to live in the machine rather than in the garage. The value is not the individual tools, it is that everything needed for a trailside repair is in one roll instead of scattered across a toolbox at home. Pair one with a tire plug kit and a portable compressor and most trail failures become a twenty-minute delay instead of a recovery.
Skid plates. Full-coverage protection for the frame, engine and drivetrain. If you ride rock, roots or stumps, a skid plate is cheaper than the component it protects. Check whether the kit covers the full belly or just the center section, and whether it includes A-arm guards, since those are usually sold separately.
Tusk Lighting, Turn Signals and Light Bars
Light bars. Choose by beam pattern first, not by lumens. A spot beam throws distance and is what you want at speed. A flood beam lights width and is what you want at low speed on tight trail. Combo bars split the difference. Mounting position matters as much as the bar: a roof-mounted bar over a windshield reflects glare back at you unless the windshield is down.
Turn signal kits. The core of most street-legal builds. A complete kit gives you front and rear signals, a switch and usually a horn. Check whether your state also requires mirrors, a windshield, DOT tires or a license plate light, because requirements vary by state and sometimes by county.
Accessory lighting. Whip lights for dune visibility, rock lights, interior lighting and replacement headlights.
Wiring is where lighting installs go wrong. Plug-and-play kits that use the machine's existing harness are worth paying for over kits that require splicing, and a fused, relayed circuit is not optional on anything drawing real current.
Tusk Pricing
Tusk sits in a specific place in the market and the pricing reflects it: house-brand economics on construction that competes with independent brands a tier up.
Tires. The Terrabite runs $167.19 to $308.74 depending on size, against an MSRP of $175.99 at the small end. That is 8-ply radial construction at a price where a lot of competing tires are 6-ply, and it is the single clearest example of what a house brand buys you. The Aramid Terrabite sits above it for the 10-ply carcass.
One shipping note specific to tires. Terrabites carry a $17.99 shared shipping charge because tires ship oversized. Factor that in when you compare a set of four against another brand, and remember a set is four.
Everything else. Wheels, windshields, roofs, doors, tool kits and lighting span a wide range depending on machine and material. Glass windshields cost more than polycarbonate and weigh more. Beadlock wheels cost more than standard. Framed soft doors cost well below full hard doors.
Free shipping applies on orders over $250, which a set of tires clears comfortably. Affirm financing is available at checkout, and our Best Price Guarantee means if you find the same product cheaper, we will match it.

Tusk FAQ
Is Tusk the same as Rocky Mountain ATV? They are connected. Tusk is the house brand of Rocky Mountain ATV/MC, a powersports company based in Payson, Utah. Riders use both names for the same products, so searching either term will get you to the same parts.
What is the Tusk Terrabite tire? Tusk's flagship all-terrain UTV and ATV tire. Radial, 8-ply rated, with 3/4-inch tread depth and a truck-style non-directional tread pattern. Rated for medium to hard terrain with load ratings up to 1,000 lb at 22 PSI depending on size. It is the tire most people mean when they say they run Tusks.
What is the difference between the Terrabite and the Aramid Terrabite? Carcass construction. The standard Terrabite is 8-ply rated. The Aramid version is 10-ply rated, built for heavier machines and sharper terrain where sidewall punctures are the recurring problem. Same tread mission, tougher casing.
Terrabite or Megabite? Terrabite for all-terrain: hard pack, gravel, desert, ranch and mixed riding. Megabite for mud and soft terrain. The Terrabite is a medium-to-hard terrain tire and it will not satisfy anyone shopping specifically because of mud.
Is the Terrabite good in mud? It handles occasional mud on the way to somewhere else. It is not a mud tire. If mud is why you are shopping, buy the Megabite.
How much does a Tusk Terrabite weigh? It varies by size. A 27x9.00-12 is 28.3 lb, a 32x10.00-14 is 39.6 lb and a 32x10.00-15 is 39.8 lb. Jumping from a 27 to a 32 adds roughly 11 lb per corner, which is enough to warrant a clutch kit on most machines.
Are Tusk parts good quality? For the price, they compete well. The Terrabite is 8-ply radial construction at a price where a lot of competing tires are 6-ply, and the Barrier doors use a steel frame rather than the all-plastic construction common at that price. Being a house brand removes a layer of margin, which is where the value comes from.
Does Tusk make parts for anything besides UTVs? Yes, a large dirt bike, ATV and street catalog including riding gear, brake components, engine parts and tools. We carry the UTV-relevant portion of the line.
What tools should I keep in my UTV? A universal tool and repair kit, a tire plug kit and a portable compressor cover most trailside failures. Add a tow strap and a basic first aid kit if you ride alone or far from the trailhead.
10 Top Selling Tusk / Rocky Mountain ATV ProductsÂ
1. Tusk Terrabite Radial UTV Tire ($167.19–$308.74) — Our best-selling Tusk product and the tire most people mean when they say they run Tusks. Radial 8-ply with 3/4-inch tread and a truck-style pattern, rated medium to hard terrain. Twenty-four sizes from 25x8-12 to 35x10-16 across 12, 14, 15 and 16-inch rims. Over 1,300 customer ratings averaging 4.8 out of 5. Note the $17.99 shared shipping charge on tires.
2. Tusk Aramid Terrabite 10-Ply Tire — Same tread mission as the standard Terrabite with a 10-ply rated carcass instead of 8. The upgrade for heavy utility machines, regular hauling, or sharp rock where sidewall punctures have been the recurring problem.
3. Tusk Teton UTV Beadlock Wheels — Beadlock construction clamps the tire bead mechanically so you can run low pressure without unseating a bead. Torque the ring bolts evenly to spec. Pairs naturally with a set of Terrabites.
4. Polaris RZR Pro R Full Glass Windshield with Vent and 16" Wiper — Glass rather than polycarbonate, which means far better scratch resistance and support for a real wiper. The vent lets you move air without dropping the windshield. Plan on two people for the install, since glass is heavy.
5. Can-Am Maverick R Removable Full Windshield, Clear and Scratch Resistant — Scratch-resistant coating on clear polycarbonate, and removable, so you can seal the cab for cold and dust and pull it for summer. The right answer if you ride across seasons.
6. Honda Pioneer 1000-5 Profile Aluminum Roof — Laser-cut, black powder-coated aluminum with anti-vibration gaskets at the mounts. The gaskets matter more than the spec sheet suggests: they are what keeps an aluminum roof from drumming at speed.
7. Polaris General 4 Framed Soft Upper Doors — Framed soft uppers close the top half of the cab against wind, rain and dust while keeping the weight and cost well below full hard doors.
8. Tusk UTV Tool Roll Kit, 67-Piece with Belt Removal Tools — Built to live in the machine rather than the garage. The belt removal tools are the detail that matters: a thrown belt is one of the most common trailside failures on a UTV, and it is not a repair you can do with a generic socket set.
9. Tusk UTV Cold Weather Seat Heater — Straightforward comfort upgrade for anyone riding through a northern winter. Pairs with a full windshield and a roof to make a machine genuinely usable in the cold.
10. Polaris RZR Plug & Play UTV Signal & Horn Kit — Turn signals and horn in one plug-and-play kit that uses the machine's existing harness, so no cutting or splicing. The core of most street-legal builds. Check your state's full requirement list before you assume signals alone are enough.
