SunF Power.II 19×7-8 ATV Tire Review
SunF Power.II 19×7-8 ATV Tire Review
Choosing a small ATV or UTV tire is mostly about fit, tread style, and load safety. The SunF Power.II 19×7-8 is a compact A051 all-terrain tire sold as a set of two for machines that use a 19-inch tire on an 8-inch wheel. This review looks at its verified specs, off-road traction, fitment limits, buyer feedback, and the situations where this 6-ply tubeless set makes sense. It is a strong value pick for trail grip, but you should check sizing and load details before using it on a heavier setup.
Quick Verdict
Rating: 8.4/10, recommended with fitment and load-rating caveats
Best For: Small ATVs, UTVs, mini bikes, go-karts, quads, and utility machines that need a 19×7-8 all-terrain replacement tire.
Bottom Line: The SunF Power.II 19×7-8 gives you a deep 16 mm, non-directional tread and a 6-ply tubeless casing in a two-tire set. The main tradeoff is that fitment and load data need careful checking before you mount it.
Before You Buy: Confirm the 19×7-8 tire size, 8-inch rim diameter, 5.5-inch rim width, wheel clearance, and your machine’s load needs. The Amazon feature table lists 220 lb load capacity, while the product description shows a conflicting Max Load value, so check the current listing and tire sidewall before heavy-duty use.

What Is the SunF Power.II 19×7-8?
The SunF Power.II 19×7-8 is the SUNF A051 Power II all-terrain tire in a compact 19×7-8 size. It is sold as two tires for off-road machines that use an 8-inch wheel and a 7-inch section-width tire.
The main appeal is the mix of 6-ply construction, tubeless design, 16 mm tread depth, and non-directional tread. That makes it more trail-focused than a basic turf tire, while still staying small enough for many mini bikes, go-karts, youth quads, and compact ATV or UTV setups.
Who Should Buy It?
Best For
- Riders replacing two 19×7-8 off-road tires on a compatible 8-inch wheel.
- Small ATV, UTV, mini bike, quad, go-kart, or utility setups that need more bite than a smooth turf tire.
- Buyers who want a value-focused 6-ply tubeless tire for dirt, grass, loose ground, and light mud.
Skip If
- Your machine needs a different tire size, rim diameter, rim width, or load rating.
- You mostly drive on pavement and want a quieter, smoother street-style tire.
- You need a gentle turf tire that will reduce lawn marking during tight turns.
Fit and Compatibility
The most important spec is the tire size: 19×7-8. In that format, 19 is the approximate tire diameter, 7 is the section width, and 8 is the wheel diameter. The listing also shows a 5.5-inch rim width, so do not treat the 8-inch number as rim width.
This tire can work only when the wheel, bead seat, fender clearance, suspension clearance, and vehicle manual all support this size. If you are replacing worn stock tires, match the sidewall size first and then check load needs, not just brand or tread style.
Pro Tip: Before ordering, take a photo of your current tire sidewall and rim markings. Compare the size, ply rating, rim diameter, and clearance with the Amazon listing and your vehicle manual before mounting.
Tread and Traction
The A051 Power II tread is listed as non-directional. That is useful because it is not built around a one-way arrow pattern, but it still needs proper mounting, bead seating, and inflation. A tire shop or experienced installer can help if you are not used to small ATV tire mounting.
The 16 mm tread depth is the main reason to consider this tire. The blocks and shoulder area are aimed at loose ground, grass, trail dirt, light mud, and turns where a smoother tire can slide. SUNF also highlights shoulder traction, which helps when the machine leans or scrubs during off-road maneuvers.
Build Quality and Durability
The 6-ply rating is a practical upgrade if you ride over rocks, roots, ruts, and packed dirt. It does not make the tire damage-proof, but it gives the casing more toughness than many lighter-duty replacement tires.
The tubeless design also fits the way many ATV and utility tires are used. You still need the correct compatible rim, a clean bead area, safe inflation, and a pressure check before riding. Do not exceed the listed 7 PSI maximum pressure.
Ride Feel on Hard Surfaces
This is an off-road tread, so it will not feel like a smooth pavement tire. On packed ground, concrete, or asphalt, you may notice more tread vibration, more steering texture, and more noise than you would get from a turf or street-style tire.
That tradeoff is normal for a more aggressive all-terrain pattern. If your riding is mostly trails, yards, fields, or loose ground, the extra bite can be worth it. If most of your use is paved paths or hard shop floors, a smoother tread may be easier to live with.
Load Capacity and Safety
The Amazon feature table lists 220 lb load capacity, load index 28, and speed rating F. The same listing’s product description also shows a conflicting Max Load value. Because tires are safety parts, you should verify the current listing, tire sidewall, and vehicle manual before using this set for hauling, towing, steep terrain, or heavier riders.
Also check pressure with a low-pressure tire gauge. ATV tires run at much lower pressure than car tires, and this listing shows a 7 PSI maximum. Overinflation can affect ride quality, bead seating, traction, and safety.
Installation and Maintenance
Small 6-ply ATV tires can be stiff during mounting. Use the right tire-mounting tools, bead lubricant, and safe inflation steps. If the bead does not seat evenly, stop and get professional help instead of forcing more pressure into the tire.
After installation, inspect the bead line, check for slow leaks, and confirm that the tire clears the fender, frame, brake parts, and suspension through steering and suspension movement. During regular use, remove stones from the tread and check pressure before rides.
How It Performs in Real Use
For Dirt Trails and Loose Ground
The SunF Power.II makes the most sense on dry dirt, loose paths, gravelly spots, and uneven trail surfaces. The deep, non-directional tread gives the tire more bite than a flat turf pattern, especially when starting, stopping, or turning on soft ground.
For Grass and Yard Utility Use
On grass, the added traction can help if your machine slips with smoother tires. The tradeoff is lawn wear. Sharp turns, spinning, or sliding can mark or tear turf more easily than a softer lawn-focused tire.
For Light Mud or Snow
The 16 mm tread depth can help in light mud, damp soil, and shallow snow. It is not a dedicated mud tire or winter tire, so deep mud, icy surfaces, and steep wet slopes still require caution and the right vehicle setup.
For Pavement and Hardpack
On pavement or very hard surfaces, expect a firmer and more textured ride. The tire can handle short hard-surface crossings, but buyers who ride mainly on pavement should compare a less aggressive tread.
What Buyers Are Saying
At review time, the Amazon listing showed strong buyer feedback for this SUNF A051 Power II tire set. Many buyers mention traction, value, and a more aggressive look as the biggest positives.
- Praise: Buyers often mention better grip in mud, snow, grass, loose rock, and hill use.
- Praise: Several reviews describe the tires as a strong value compared with other replacement options.
- Praise: The aggressive tread and small-machine fit are common reasons buyers choose this set.
- Watch-out: Some buyers mention a bumpier or noisier ride, and aggressive tread can be rough on lawns.
Pros and Cons
Pros
- 6-ply tubeless construction gives you a tougher casing for off-road use.
- 16 mm tread depth helps on dirt, grass, loose terrain, and light mud.
- Non-directional A051 tread is practical for mixed trail and utility use.
- Sold as a two-tire set, which is useful when replacing both tires on an axle.
- Multiple listing details confirm the 19×7-8 size, 8-inch rim diameter, and 5.5-inch rim width.
Cons
- Rims are not included, so you need compatible wheels already installed or purchased separately.
- Load information is not perfectly consistent across the listing, so load-sensitive use needs extra checking.
- Aggressive tread can feel louder or bumpier on hard surfaces and may damage delicate turf.
Is It Worth the Price?
The SunF Power.II 19×7-8 is worth considering if you want a value-focused off-road tire set rather than a premium tire line. Its value comes from the two-tire count, 6-ply rating, tubeless construction, and deep tread.
You will get the most value from it if your machine already uses the 19×7-8 size and you ride mainly on dirt, grass, trails, or mixed off-road surfaces. It is not the best fit if you need a quiet pavement tire, a lawn-friendly turf tire, or fully clear load data for heavy utility work.
How It Compares to Alternatives
If you want another SUNF tire in the same general size range, compare the SunF A027 19×7-8 for a sport-style tread or the SunF A021 19×7-8 for firmer hardpack use. If you want another budget all-terrain option, a Ktaxon 19×7.00-8 6-ply set may also be worth comparing.
The Power.II A051 makes the most sense if you want a compact, aggressive, non-directional all-terrain tread with a 6-ply tubeless build. Alternatives may be better if you need a smoother hard-surface ride, a softer turf pattern, or a different tire profile.
Frequently Asked Questions
Does the SunF Power.II 19×7-8 come as one tire or two?
The Amazon listing is for a set of two tires. Rims are not included, so you need compatible 8-inch wheels separately.
What rim size fits the 19×7-8 tire size?
The 19×7-8 size uses an 8-inch rim diameter. The listing also shows a 5.5-inch rim width, so confirm rim width, bead seat, and clearance before mounting.
Is the SunF Power.II A051 directional?
No. The A051 Power II tread is listed as non-directional, which means it is not built around a one-way directional tread pattern.
Can this tire be used on the front or rear?
The listing does not limit the tire to front-only or rear-only use. Fit depends on your vehicle’s tire size requirements, axle setup, rim size, clearance, and load needs.
Is it good for pavement?
It can handle short hard-surface use, but it is mainly an off-road tire. On pavement, expect more tread feel and noise than a smoother street or turf tire.
What PSI should you use?
The listing shows a 7 PSI maximum pressure. Follow the tire sidewall, product listing, and your vehicle manual, and use a low-pressure gauge made for ATV tires.
Why does the load rating need extra checking?
Amazon’s feature table lists a 220 lb load capacity, but the product description includes a conflicting Max Load value. Check the current product page and tire sidewall before using it for heavy riders, cargo, towing, or steep terrain.
Who should skip this tire?
Skip it if your machine does not use the 19×7-8 size, if your wheels are not compatible, or if your use case depends on a clearer load rating. You should also compare a smoother tire if your riding is mostly pavement or delicate lawn use.
The Bottom Line
The SunF Power.II 19×7-8 ATV tire is a smart buy if you need a compact, 6-ply, tubeless, off-road tire set with strong traction on dirt, grass, loose ground, and light mud. Skip it if you need a quiet pavement tire, a gentle turf tire, or a different size. Its main strength is value-focused trail grip, while its main limitation is the need to verify fitment and load details before use.
