Choosing replacement ATV or UTV tires starts with fit, load limits, and terrain, not tread appearance alone. The TRIBLE SIX 20×11-9 tires are a set of two tubeless, 6-ply-rated bias tires made for 9-inch rims and mixed off-road use. Their wide profile and 13 mm tread are useful for loose ground, but the size will not fit every machine and the tires are not intended for highway travel. This review explains the verified specifications, likely strengths, practical limits, and checks you should make before ordering.
Quick Verdict
Rating: 8/10, recommended with fitment caveats
Best For: ATV and UTV owners who need a wide 20×11-9 rear tire for trails, dirt, mud, sand, or property use
Bottom Line: The 6-ply-rated casing, 13 mm tread, and non-directional pattern make this pair a practical mixed-terrain option. The main tradeoff is limited compatibility, so you must confirm rim diameter, rim width, clearance, load needs, and axle placement before buying.

- The size code means a 20-inch overall diameter, 11-inch section width, and fitment for a 9-inch rim diameter.
- The listed 8.5-inch measurement is rim width, which is different from the 9-inch rim diameter in the tire size.
- The tires use bias construction, a tubeless design, a 6-ply rating, and a 13 mm non-directional tread.
- Each tire is listed for up to 340 lb at a maximum of 22 PSI, but your machine manual may require a lower operating pressure.
- They are intended for off-road use and should not be treated as highway tires.

What Are the TRIBLE SIX 20×11-9 Tires?
The TRIBLE SIX 20×11-9 tires are wide, low-profile powersports tires sold as a pair. The listing places them in the ATV/UTV all-terrain category and identifies them as bias-ply, tubeless tires with a non-directional tread. Their 20-inch diameter and 11-inch section width make them most likely to serve as rear tires on machines that already use this exact size.
The main selling point is a combination of width, tread depth, and a 6-ply rating. The 13 mm knobs are intended to find traction on dirt, mud, rocks, and loose trail surfaces, while the broad footprint can help spread the load. These benefits only apply when the tire fits the wheel, clears the suspension and bodywork, and stays within the machine manufacturer’s load and pressure limits.
Who Should Buy It?
Best For
- ATV or UTV owners replacing an existing 20×11-9 tire on a compatible 9-inch wheel
- Riders who use dirt, trail, mud, sand, or mixed off-road surfaces
- Property owners using compatible utility machines or golf carts away from public roads
Skip If
- Your wheel is not 9 inches in diameter or your approved rim width differs from the listing
- You need a DOT-approved highway tire or regularly travel on paved public roads
- Your required load capacity, clearance, or axle position does not match this size
Before You Buy: Do not order by vehicle type alone. Match the full 20×11-9 size, wheel diameter, approved rim width, load requirement, clearance, and front or rear position listed in your owner’s manual or on your current tire.
TRIBLE SIX 20×11-9 Specs and Fitment
The 20×11-9 size code is the first compatibility check. It indicates an overall diameter of about 20 inches, a section width of about 11 inches, and a 9-inch wheel diameter. The separate 8.5-inch figure in the listing refers to rim width, not wheel diameter. Confusing those two measurements can lead to an incorrect purchase.
The tires have a listed load index of 40, a maximum load of 340 lb per tire, and a speed rating of F. Load and speed ratings are limits, not performance targets. Your machine’s placard or owner’s manual should control the final tire choice, inflation pressure, and maximum operating speed.
Because this is a two-tire package, confirm if you are replacing both tires on one axle or trying to build a four-tire set. Mixing tread designs, sizes, wear levels, or constructions on the same axle can change steering and handling. When in doubt, ask a qualified powersports tire installer to confirm the setup.
Tread Design and Traction
The non-directional split-knob pattern lets the tires be mounted without a required forward tread direction, provided all other installation requirements are followed. Open spaces between the knobs can help the tread find edges in dirt and loose soil. The 13 mm depth also gives the tire more usable rubber than a shallow turf pattern.
The wide, relatively flat profile creates a broad contact area. On firm dirt and packed trails, that can support stable forward drive and predictable cornering. In soft sand or loose ground, the footprint may help the tire stay on top of the surface, although actual flotation depends on vehicle weight, pressure, speed, and terrain.
Mud performance will depend on how quickly the tread clears. The pattern is more aggressive than a smooth turf tire, but it is not described as a dedicated deep-mud design. Buyers who spend most of their time in thick mud may prefer taller, more widely spaced lugs.
Ride Comfort, Load Capacity, and Durability
A 6-ply rating gives the casing more resistance to cuts and punctures than a lighter-duty tire of the same general type, but it does not make the tire puncture-proof. Sharp rocks, metal, roots, sidewall pinches, and incorrect pressure can still cause damage. Inspect the tread and sidewalls before each ride, especially after impacts.
The listed 340 lb capacity applies per tire under the listing’s stated conditions. Two tires do not automatically give every machine a 680 lb usable payload because axle ratings, vehicle weight, passengers, cargo, wheel capacity, and suspension limits also matter. Never use tire capacity to override the vehicle manufacturer’s limits.
Bias construction can provide a sturdy feel and useful sidewall support for low-speed off-road use. The tradeoff is that bias tires may feel firmer and create more rolling resistance than some radial alternatives. Ride comfort will also change with inflation pressure, terrain, and vehicle suspension.
How It Performs in Real Use
[Products Worth Considering]
This flat-free TICONN wheelbarrow tire features durable polyurethane foam construction that never needs inflation, helping prevent punctures and reducing maintenance on rough outdoor terrain. With a 300 lb max load capacity and stable steel rim design, it supports safer transport for yard work and hauling tasks. An adapter kit with ball bearings and nylon spacers is included for easier fit and customization across common wheelbarrow and cart axle setups.
Replace or upgrade your zero-turn lawn mower tires with a universal fit flat-free tire and wheel assembly in a convenient 2-pack. Smooth tread front-caster style helps turning with reduced turf damage, while flat-free design eliminates the maintenance and downtime of air-filled flats. The included adapter kit supports 5/8-inch axles and hub lengths from 3.4 to 5 inches for compatibility across most ZTR mowers.
TireJect Off-Road Tire Sealant Kit provides 5-in-1 sealing to help fix tread punctures up to 3/8", sidewall punctures up to 3/8", bead leaks, slow leaks, and minor dry rot on low-speed tires. It permanently seals with liquid rubber, recycled tire particles, and Aramid fibers, making it ideal for flats caused by thorns, nails, and screws. The included dispensing cap attaches to the valve stem for a no-mess installation, along with a metal valve core remover tool and valve stem cap. This kit is for off-road use only.
On Packed Trails and Dirt
The broad 11-inch section and split-knob tread are well suited to machines that need steady rear traction on packed dirt. You should expect the tire to favor controlled, low-speed off-road use rather than fast pavement handling. Correct pressure is critical because overinflation can reduce the contact patch and make the ride harsher.
In Mud and Loose Soil
The 13 mm tread can bite into softer surfaces, and the open knob layout gives mud and loose soil room to move. It should handle moderate mud better than a shallow turf tire. For deep, sticky mud, a dedicated mud tire with taller and more widely spaced lugs may clear more effectively.
On Rocks and Uneven Ground
The 6-ply-rated casing and bias construction are useful where puncture resistance and sidewall support matter. You still need to avoid sharp impacts and check for cuts after rocky rides. Do not lower pressure below the vehicle or tire guidance in an attempt to gain traction, because excessive deflection can damage the bead or sidewall.
For Utility and Property Use
On compatible golf carts, lawn equipment, or utility machines, the wide footprint can provide stable movement over dirt, gravel, and unpaved property. The tread may mark soft turf more than a dedicated lawn tire, especially during tight turns or when the ground is wet. Confirm that the tire’s size, load rating, and tread aggressiveness suit the surface you need to protect.
Fit, Installation, and Pressure Tips
- Read the sidewall and manual: Match the complete size and follow your machine manufacturer’s approved tire specifications.
- Check wheel dimensions: These tires require a 9-inch rim diameter, and the listing states an 8.5-inch rim width.
- Confirm clearance: Measure space around the suspension, fender, chain, brake parts, and bodywork before changing from another size.
- Replace axle pairs when appropriate: Similar tread depth and construction on the same axle help keep handling balanced.
- Use proper mounting equipment: Tire beads can be damaged or can seat violently. Professional installation is the safer choice if you lack tire-mounting tools and training.
- Set cold pressure correctly: Treat 22 PSI as the listed maximum, not an automatic operating target. Use the vehicle manufacturer’s pressure guidance.
- Recheck after installation: Inspect bead seating, leaks, lug torque, clearance, and pressure before riding.
Pro Tip: Photograph the current tire sidewall and wheel markings before ordering. This gives you a quick record of size, construction, load data, and rim information to compare with the listing.
Compatibility and Safety
These tires are intended for off-road ATV/UTV use and are not presented as highway tires. Do not use them on public roads unless the tire markings, vehicle approval, and local laws clearly allow it. A speed rating does not make an off-road tire road legal.
Never exceed the tire, wheel, axle, or vehicle limits. Use the lowest applicable limit when specifications differ. After mounting, check pressure when the tires are cold, inspect for leaks, and stop using any tire with exposed cords, deep cuts, bulges, bead damage, or repeated pressure loss.
Store unused tires in a cool, dry place away from direct sunlight, electric motors, solvents, fuel, and ozone sources. Outdoor exposure can speed cracking and aging. Even tires with deep tread should be replaced when age or damage makes them unsafe.
Pros and Cons
Pros
- Sold as a matched set of two tires
- 6-ply-rated bias construction for off-road durability
- 13 mm non-directional tread for mixed dirt, trail, mud, rock, and sand use
- Tubeless design simplifies compatible wheel setups
- Wide 11-inch section creates a broad contact area
Cons
- Fits only compatible 9-inch wheels and approved rim widths
- Not intended for highway travel
- Mixed-terrain tread may not match a dedicated deep-mud or turf tire
Is It Worth the Price?
The TRIBLE SIX pair is worth considering when you need two 20×11-9 tires and value a 6-ply rating, deep tread, and broad mixed-terrain use. Buying a pair can make axle replacement simpler than sourcing two separate tires, and the verified specifications cover the main details needed for an initial fit check.
Value drops quickly if the fit is wrong or your terrain requires a specialized tread. It is not the best choice for buyers who need road legality, a dedicated deep-mud tire, a turf-friendly pattern, or a different rim width. Compare the current price with installation costs and similar 20×11-9 pairs before deciding.
How It Compares to Alternatives
SunF A027 and A035 tires are common alternatives in the same 20×11-9 size, while the Maxxis Razr is a better-known sport-oriented option. Compare ply rating, tread shape, load limits, package quantity, and approved rim width rather than choosing by size alone.
The TRIBLE SIX set makes the most sense when you want a two-tire package with a non-directional mixed-terrain pattern. A more specialized mud, racing, or turf tire may be better when one surface dominates your use.
Frequently Asked Questions
Does 20×11-9 mean the tire fits an 8.5-inch rim?
No. The final number in 20×11-9 identifies a 9-inch rim diameter. The listing separately gives an 8.5-inch rim width, so you need to confirm both diameter and width.
Are the TRIBLE SIX 20×11-9 tires tubeless?
Yes, the listing identifies them as tubeless tires. Your wheels must also be compatible and in good condition for a reliable tubeless seal.
How many tires are included?
The product is listed as a set of two tires. Confirm the package quantity on the Amazon page before checkout because marketplace listings can change.
What pressure should you use?
The listing gives 22 PSI as the maximum. Your actual cold operating pressure should follow the vehicle manufacturer’s guidance and must not exceed the lowest applicable tire, wheel, or vehicle limit.
Can you use these tires on paved roads?
They are intended for off-road use and are not described as highway tires. Occasional private-property pavement is different from public-road use, so check tire markings, vehicle approval, and local rules.
Will they fit every ATV, UTV, lawn mower, or golf cart?
No. Vehicle category alone does not confirm fit. Match tire size, rim dimensions, clearance, load capacity, axle position, and manufacturer approval before ordering.
Are these dedicated mud tires?
No, the listing presents them as all-terrain mud and trail tires. Their 13 mm tread should suit mixed surfaces, but a dedicated deep-mud tire may clear thick mud more effectively.
How should you store unused tires?
Keep them cool, dry, and out of direct sunlight. Avoid ozone sources, fuels, oils, and solvents, and inspect the rubber for cracking or deformation before installation.
The Bottom Line
The TRIBLE SIX 20×11-9 pair is a solid option for compatible ATV and UTV owners who need wide, 6-ply-rated tubeless tires for mixed off-road terrain. Skip it when you need highway approval, a different wheel specification, or a highly specialized mud or turf tread. Its strongest points are the complete two-tire package and verified off-road specifications, while exact fitment remains the key limitation.
