The best fit for you
- For a standard ATV owner: If you need a reliable full set for a typical ATV, the XT400's 10-ply radial construction and 32x10-14 size fit most mid-size machines. See pick 1
- For a large UTV or heavy rig: When you run a bigger vehicle with taller clearance, the XT400W full set in 44x12-24 gives you the same 10-ply strength in a much larger footprint. See pick 2
- For a staggered or mixed fit: If your ATV uses different front and rear widths, the SS360's set of two 32x10-15 and two 32x12-15 is ready to bolt on. See pick 6
- For replacing only two tires: When only the front or rear axle needs new rubber, the XT400W pair gives you two 44x12-24 tires without paying for a full set. See pick 7
Our 7 picks
1 Best overall
The XT400 is the most balanced choice in the System 3 range: a 10-ply radial in the common 32x10-14 size, supplied as four tires. It beats the 8-ply options on toughness while staying in a size that fits most ATVs without lift kits.
Pros
- 10-ply construction
- Radial tire construction
- Full set of four tires
- 32x10-14 size
Cons
- Only available in 32x10-14 size
- No pair option for just two tires
Good fit if
- ATV owners who want a heavy-duty tire in a standard size
- Riders who do mixed trail and mud work
Skip if
- You need a 15-inch wheel diameter tire
- You operate a larger UTV that demands a bigger footprint
Verdict: A straightforward, high-ply full set that covers the majority of ATV applications.
2 Best for large UTVs
The XT400W in 44x12-24 is the biggest tire in the pool, retaining the 10-ply radial construction while adding 12 inches of width and a 24-inch rim. That combination suits heavy UTVs and side-by-sides that need extra ground clearance.
Pros
- 10-ply construction
- 44x12-24 size for large machines
- Full set of four tires
Cons
- Requires 24-inch rims
- Large size may not fit stock UTVs
Good fit if
- Owners of full-size UTVs and side-by-sides with 24-inch rims
- Drivers who frequently cross deep mud or rock
Skip if
- Your vehicle uses 14 or 15-inch rims
- You need a lighter tire for utility work
Verdict: The maximum-size System 3 tire for serious off-road duties.
3 Best 8-ply all-rounder
The XTR370 offers a 33x10-15 size with 8-ply radial construction, a good compromise between weight and durability. It's narrower than the XC450, which helps fit most ATVs without spacers.
Pros
- 8-ply construction
- Radial tire construction
- Full set of four tires
- 33x10-15 size
Cons
- Only in 33x10-15 size
- No pair option
Good fit if
- Riders looking for a capable trail tire without extra weight
- ATVs with 15-inch rims and moderate power
Skip if
- You need a 10-ply tire for rocky, high-impact trails
- Your vehicle requires a 14-inch rim
Verdict: A dependable middle-ground choice for everyday off-roading.
4 Best 10-ply for 35-inch wheels
Full set of System 3 XC450
- Vehicle
- ATV and UTV
$1,124.80 price as of 2026-10-05 05:43 UTC (Details) Typical price: $1,205.08, 7% off
The XC450 pairs a 35x10-15 size with 10-ply radial construction, giving you the largest diameter in the 15-inch rim group while keeping the same width as the XCR350. That extra ply count makes it the sturdier option for heavier loads.
Pros
- 10-ply construction
- Radial tire construction
- 35x10-15 size fits many lifted ATVs
- Full set of four tires
Cons
- Only in 35x10-15 size
- Large diameter may require suspension or clearance modifications
Good fit if
- ATV owners who prioritize toughness over light weight
- Riders who tackle rocky trails and deep mud
Skip if
- Your ATV has stock suspension that won't clear a 35-inch tire
- You want a lighter tire for better acceleration
Verdict: The burliest 15-inch System 3 tire in this lineup.
5 Best 8-ply 35-inch value
The XCR350 gives you the same 35x10-15 dimensions as the XC450 but drops to 8 plies, which typically makes it lighter and easier on the driveline. It's a solid choice for riders who want big tires without the added weight of a 10-ply.
Pros
- 8-ply construction
- Radial tire construction
- 35x10-15 size for maximum clearance
- Full set of four tires
Cons
- Only in 35x10-15 size
- No pair option for two-tire replacements
Good fit if
- ATV owners who want a large tire but still need light steering effort
- Trail riders who don't constantly run over sharp rocks
Skip if
- You carry heavy loads and need the extra ply strength
- Your vehicle is underpowered for a 35-inch tire
Verdict: A balanced 35-inch tire that trades a little durability for easier handling.
6 Best staggered set
Full set of System 3 SS360 32x10-15 and 32x12-15 ATV Tires
- Vehicle
- ATV and UTV
$955.76 price as of 2026-10-05 05:43 UTC (Details)
The SS360 is the only tire in the pool that comes with two different widths: two 32x10-15 and two 32x12-15. That makes it a direct fit for ATVs that run a wider rear track, saving you from buying two separate sets.
Pros
- Includes two narrower front tires and two wider rear tires
- Full set of four tires
- 32x10-15 and 32x12-15 sizes
Cons
- Size mix is not configurable
- Ply count not stated by the seller
Good fit if
- ATV owners with staggered wheels who want a matched set
- Riders who prefer a wider rear footprint for stability
Skip if
- Your machine uses the same width on all four corners
- You need a specific tire strength specification
Verdict: A practical solution for staggered fitments straight out of the box.

- Vehicle
- ATV and UTV
- Sold as
- Set of 2
$974.02 price as of 2026-10-05 06:08 UTC (Details)
When you only need to replace two tires on a big UTV, this pair of XT400W 44x12-24 tires offers the same 10-ply radial construction as the full set but at a lower initial outlay. It's the only pair option in the entire System 3 pool.
Pros
- 10-ply construction

- Available as a pair of two tires
Cons

How the picks were chosen
We identified 7 System 3 Off-Road tire listings in the catalogue, all for ATV and UTV use. From those, we shortlisted every one, since the pool holds fewer than 12. We compared each listing's stated specifications: ply count (8 or 10), radial versus bias construction, tire dimensions, and whether the set includes two or four tires. We also checked that the seller lists the set size clearly. Prices are read from the store at the time the page loads; they are not part of the comparison. No tire in this guide has been tested or measured by us; all claims are based on the maker's published information and the listing text.
Picking the right one for you
Ply count: 8 vs 10
The ply count is the number of layers in the tire's carcass construction. The pool includes 8-ply tires (XTR370, XCR350) and 10-ply tires (XT400, XT400W, XC450). The SS360 listing does not state its ply count. A higher ply count generally means a more robust carcass, but the actual performance depends on many factors; we do not have independent test data.
Radial versus bias construction
All System 3 tires in this pool use radial construction, where the ply cords run perpendicular to the tread centerline, as defined by FMVSS No. 109. Radials typically provide a smoother ride and longer tread life at speed compared with bias tires, but the difference is not tested here.
Tire size and rim fit
Tire sizes like 32x10-14 are written as overall diameter x section width - rim diameter. The first number is height, the second is width, and the third is the wheel size. Always match the rim diameter to your wheel; a 14-inch tire needs a 14-inch rim. Also check the width and height against your vehicle's clearance and suspension travel. The 44x12-24 XT400W is the largest size and may require a lift; the 32x10-14 and 33x10-15 sizes fit stock ATVs. Measure before you buy to avoid rubbing.
Full set versus pair
A full set of four tires is the simple way to equip a vehicle, but some riders only need two when an axle wears out faster. The pool includes one pair option: the XT400W in 44x12-24. If you're replacing just front or rear, a pair is more budget-friendly. For staggered fitments, the SS360 provides two different widths in one package. Decide whether you want all four new tires or just the worn axle, and confirm the set size (quantity) in the listing.
Vehicle compatibility
Every tire here lists 'ATV and UTV' as its intended use, but not every tire fits every machine. The largest sizes (44x12-24) are meant for big side-by-sides; standard ATVs usually run 14- or 15-inch rims with widths around 10 or 12 inches. Check the tire's dimensions against your manufacturer's recommended tire size, which you'll find in the owner's manual or on the vehicle placard. Over-sizing can stress drivetrain parts, while under-sizing reduces ground clearance. Regulatory standards like FMVSS No. 110 cover tire selection for light vehicles, but ATV-specific fitment depends on the vehicle design.
Set quantity and packaging
The listing identifies whether the product is a 'full set' of four tires or a 'pair' of two. The XT400, XT400W full set, XTR370, XC450, XCR350, and SS360 all come as sets of four. The only pair is the XT400W pair. If you need a complete set, a full-set listing saves you from mixing batches and potentially getting mismatched wear. If you only need two, a pair is efficient. Always confirm the quantity in the product name before ordering to avoid surprises.
Questions
What does 10-ply mean in a System 3 tire?
Ply count is a measure of the tire's structural strength, originally based on the number of fabric layers. A 10-ply tire is built to carry heavier loads and resist punctures better than an 8-ply, but it also weighs more and can ride stiffer. All System 3 tires in this pool except the XTR370, XCR350, and SS360 are 10-ply; the SS360 has no ply count stated.
Are these tires radial or bias?
Every tire in the System 3 off-road lineup shown here is radial, meaning the ply cords run at approximately 90 degrees to the tread centerline. The product names include the word 'Radial.' Radial tires typically provide more flexible sidewalls, better ride comfort, and more even tread wear compared to bias designs.
What do the numbers in a size like 32x10-14 mean?
The first number is the overall diameter in inches (32), the second is the section width (10), and the third is the rim diameter (14). So a 32x10-14 tire is 32 inches tall, 10 inches wide, and fits a 14-inch wheel. Always match the rim diameter to your wheel, and check the width and height for clearance.
Can I buy a single tire or must I buy a set?
The pool contains only full sets of four or one pair of two. There is no single-tire listing. If you only need one tire, you would likely have to buy a pair and keep the spare. The pair option is the XT400W in 44x12-24; every other tire is sold as a set of four.
Are these tires street-legal?
The listings state 'ATV and UTV' use, which includes off-road terrain. Street legality depends on your state's regulations and whether the tire meets any required DOT markings, which are not specified in the listings. Check local laws before using them on public roads.
