Replacing ATV tires is not just a matter of choosing an aggressive tread. You also need the correct front and rear sizes, compatible 10-inch rims, suitable load ratings, and a design that matches where you ride. The MOTOOS 21×7-10 front and 22×10-10 rear ATV/UTV tire set combines four tubeless, bias-construction tires with a non-directional split-knob tread for mixed off-road terrain. It is a practical option for trail, dirt, gravel, sand, and moderate mud use, but you should skip it when your machine calls for different sizes or when you need highway-approved tires.
Quick Verdict
Rating: 8.2/10, recommended with fitment caveats
Best For: ATV and UTV owners replacing a 21×7-10 front and 22×10-10 rear setup for mixed off-road riding
Bottom Line: The MOTOOS set gives you a complete four-tire package, useful tread depth, and a non-directional pattern for varied terrain. Its main tradeoff is limited compatibility, since the tires require the correct 10-inch wheel setup and are not intended for highway use.

Key Takeaways
- You receive two 21×7-10 front tires and two 22×10-10 rear tires for 10-inch rims.
- The 15 mm front tread favors steering bite, while the wider rear tires provide a larger contact area for drive traction.
- The tubeless bias construction and 4/6-ply-rated description make the set suitable for routine trail and utility use.
- The non-directional split-knob pattern is designed for mud, dirt, gravel, sand, and mixed trails.
- Fitment is the deciding factor. Confirm tire size, rim width, clearance, load needs, and manufacturer approval before ordering.
What Is the MOTOOS ATV/UTV Tire Set?
This MOTOOS package is a staggered set of four off-road tires: two narrower 21×7-10 tires for the front axle and two wider 22×10-10 tires for the rear. All four mount on 10-inch rims, use tubeless bias construction, and carry a non-directional tread pattern.
The set is made for riders who want one matched-size purchase rather than ordering front and rear pairs separately. The front tires list a 15 mm tread depth and 205-pound maximum load per tire. The rear tires list an 11 mm tread depth and 374-pound maximum load per tire. MOTOOS also lists an F speed index and 14 PSI for both sizes.
The listing describes compatibility with many ATVs and UTVs, plus select lawn mowers and utility vehicles. That broad description should be treated as a starting point, not a guaranteed fit for a specific make, model, or model year.
Who Should Buy It?
Best For
- Machines already specified for 21×7-10 front and 22×10-10 rear tires
- Riders who use dirt, gravel, sand, mud, and mixed recreational trails
- Buyers who need a complete four-tire set without rims
Skip If
- Your owner’s manual specifies different tire sizes, rim widths, or load ratings
- You need DOT-approved or highway-use tires
- You want wheels included or a pre-mounted tire-and-wheel package
Before You Buy: Read the size molded into your current tire sidewalls and confirm it against the vehicle manual. Matching the 10-inch rim diameter alone is not enough. You also need suitable rim width, fender and suspension clearance, load capacity, and front-to-rear sizing.
Fit and Compatibility
ATV tire sizes are written as overall diameter, tire width, and rim diameter. A 21×7-10 front tire is about 21 inches tall, 7 inches wide, and designed for a 10-inch rim. A 22×10-10 rear tire is about 22 inches tall, 10 inches wide, and also fits a 10-inch rim.
The listing pairs the front tire with a 5.5-inch rim width and the rear with an 8-inch rim width. Before ordering, compare those figures with your current wheels and the approved range in your service information. A tire can share the correct rim diameter but still be too wide, too tall, or unsuitable for the wheel.
Also check clearance at full steering lock and through the suspension’s travel. A taller or wider replacement can rub a fender, brake line, tie rod, or suspension component. On four-wheel-drive machines, using an unapproved size combination can also affect the intended front-to-rear rolling relationship.
Pro Tip: Photograph all four tire sidewalls before shopping. Keep the size, ply marking, load information, and rotation markings visible so you can compare the new set without relying on memory.
Tread Design and Off-Road Traction
The MOTOOS set uses a non-directional split-knob tread. Because the pattern does not require a single rotation direction, mounting is simpler than it is with directional tires. The open spaces between the knobs are intended to find grip on loose surfaces and clear debris as the tire rotates.
The 21×7-10 front tires have 15 mm of listed tread depth. Their narrower profile is suited to steering duties, where predictable response and the ability to cut through loose topsoil matter. The 22×10-10 rear tires are wider and use an 11 mm listed tread depth, giving the driven axle a broader footprint.
This layout makes the set most convincing on mixed trails rather than one specialized surface. It should handle hard-packed dirt, gravel roads, sandy areas, and moderate mud without forcing you into a highly specialized mud or race tread. Deep mud, sharp rock, and high-speed competition may call for a more purpose-built tire.
Construction, Load Ratings, and Durability
MOTOOS lists bias construction and describes the set as 4/6-ply rated. A ply rating is a strength classification, not a literal count of fabric layers. The listing does not clearly assign the 4-ply and 6-ply descriptions to each axle, so inspect the sidewall markings when the tires arrive.
The front tires list a maximum load of 205 pounds each, while the rear tires list 374 pounds each. Do not choose a tire only by adding those numbers together. The vehicle manufacturer’s axle limits, cargo limits, passenger limits, and recommended tire specifications still control what is safe for your machine.
The seller says the casing is designed to resist punctures and abrasions. That is useful for routine trail hazards, but no pneumatic tire is puncture-proof. Sharp rocks, metal, roots, low-pressure sidewall pinching, overloading, and damaged rims can still cause a failure.
Tubeless Design and Tire Pressure
All four tires are listed as tubeless. A tubeless setup removes the inner tube and can make small tread-area punctures easier to service with an appropriate repair method. It still requires a compatible, undamaged tubeless rim, a good valve stem, and a clean bead seat.
The Amazon listing shows 14 PSI for both sizes. Treat that figure as product information, not as permission to ignore your vehicle manual or the tire sidewall. The correct operating pressure can depend on load, terrain, wheel design, and the machine manufacturer’s instructions.
Check pressure when the tires are cold and use an accurate low-pressure gauge. Underinflation can increase sidewall flex, heat, steering effort, and the risk of bead damage. Overinflation can reduce the contact patch and make the ride harsher.

How It Performs in Real Use
Mixed Trail Riding
For trails that alternate between packed dirt, loose gravel, shallow mud, and small sandy sections, the split-knob pattern offers a useful all-around approach. The narrower front pair should help the machine track and turn, while the wider rear pair supports drive traction.
Farm and Utility Work
The wider rear footprint and listed 374-pound rear load rating may suit light utility work when the tire sizes match the machine. You still need to stay within the ATV or UTV’s rated payload and towing limits. These tires do not increase the vehicle’s factory capacity.
Sand and Loose Soil
The wider 22×10-10 rear tires spread the machine’s weight over more tread than the front pair. That can help with forward traction on loose surfaces, but pressure changes should remain within the tire and vehicle manufacturer’s guidance. Very soft dunes may favor dedicated paddle or sand tires.
Mud and Rocky Ground
The open knob pattern can work through moderate mud and uneven terrain, but this is not an extreme mud tire or rock-crawling design. Riders who spend most of their time in deep clay, jagged rock, or high-puncture environments may benefit from a more aggressive tread and a clearly specified heavier ply rating.
Fit and Installation Tips
- Confirm all four sizes: Do not assume the front and rear tires are identical. This set uses 21×7-10 in front and 22×10-10 in back.
- Inspect the wheels: Bent flanges, corrosion, damaged bead seats, and worn valve stems can prevent a reliable tubeless seal.
- Check the sidewall markings: Verify size, load, pressure, ply rating, and any rotation guidance before mounting.
- Use proper mounting equipment: ATV tire beads can be stiff. A qualified tire shop is the safer choice when you lack the correct tools and experience.
- Recheck clearance: Turn the steering from lock to lock and compress the suspension safely to look for rubbing.
- Monitor pressure: Check cold pressure after installation and before rides, especially during the first several heat cycles.
Compatibility and Safety
These are off-road tires and the listing states they are not intended for highway use. Do not treat the F speed index as approval for public-road operation. Road legality depends on the tire, vehicle, equipment, and local rules.
Never exceed the load or pressure molded into a tire’s sidewall. Replace a tire that shows exposed cords, bead damage, deep cuts, bulges, or repeated air loss. When a puncture or rim problem is uncertain, have it inspected by a qualified tire professional.
New tires can change steering effort, ride height, and handling. Ride at a controlled speed until you understand the new response, and recheck lug-nut torque according to the wheel or vehicle manufacturer’s procedure after installation.
Pros and Cons
Pros
- Complete set with two front and two rear tires
- Verified 21×7-10 and 22×10-10 staggered sizing for 10-inch rims
- Non-directional split-knob tread for varied off-road surfaces
- Tubeless bias construction simplifies the basic tire setup
- Useful listed tread depths and separate front and rear load ratings
Cons
- Not intended for highway use
- Rims are not included, and fit is not guaranteed for every ATV or UTV
- The listing’s 4/6-ply wording does not clearly identify the rating of each tire size
Is It Worth the Price?
This MOTOOS package is best viewed as a value-oriented complete replacement set rather than a specialized premium tire. It can offer strong value when you need all four tires in the exact listed sizes. Buying a matched front-and-rear set is convenient, and the tread design is versatile enough for riders who use several kinds of off-road terrain instead of one specialized surface.
The value drops quickly when fitment is uncertain. You may also need to budget for professional mounting, new valve stems, disposal fees, or wheel service. It is worth considering when your machine already uses this size combination and you want a practical all-terrain replacement, but it is not the best fit when you need road legality, extreme mud performance, or rims included.
How It Compares to Alternatives
The SunF A001 and WANDA sport ATV sets are real alternatives available in the same general 21×7-10 front and 22×10-10 rear size combination. SunF is worth comparing when you want a clearly marketed 6-ply option, while WANDA is worth a look when you prefer its cross-country-focused tread design.
The MOTOOS set makes the most sense when you want a non-directional split-knob tread, the listed 15 mm front and 11 mm rear tread depths, and a four-tire package. Compare sidewall ratings, load limits, tread style, seller support, and exact fit before choosing among them.
Frequently Asked Questions
Are rims included with the MOTOOS tire set?
No. The package includes two 21×7-10 front tires and two 22×10-10 rear tires only. You need compatible 10-inch rims, and the listing identifies 5.5-inch front and 8-inch rear rim widths.
Will these tires fit every ATV or UTV?
No. The listing describes broad compatibility, but your machine must support the exact front and rear sizes, rim dimensions, load ratings, and clearances. Confirm fit through the owner’s manual, current tire sidewalls, or a qualified dealer.
Are these tires tubeless or tube-type?
They are listed as tubeless. They need tubeless-compatible rims, sound bead seats, and suitable valve stems to hold air correctly.
What tire pressure should you use?
The product listing shows 14 PSI for both sizes. Check the tire sidewall and your vehicle manual before use, because the correct cold operating pressure must suit the machine, load, wheel, and terrain.
Can you use these tires on highways?
No. The listing states that the tires are not intended for highway use. Choose properly approved tires when your vehicle will operate on public roads.
How many tires arrive in the package?
The set contains four tires: two front and two rear. The seller notes that a multi-tire order may ship in separate packages, so the boxes may not arrive on the same day.
What is the most common buying mistake with this set?
The most common mistake is checking only the 10-inch rim diameter. You must also match the complete tire sizes, wheel widths, vehicle clearance, load needs, and approved front-to-rear combination.
The Bottom Line
The MOTOOS 21×7-10 front and 22×10-10 rear tire set is a solid buy for riders whose machines already use this exact staggered size combination and who spend most of their time on mixed off-road terrain. Its strengths are the complete four-tire package, non-directional all-terrain tread, and clear front and rear specifications. Skip it when you need highway tires, wheels included, or a different size or ply rating.
