1. Kenda Loadstar K353: Best Overall
The Kenda Loadstar K353 is a reliable bias-ply tire that consistently receives positive owner feedback for its load-carrying ability and tread life. In our evaluation of spec sheets, it offers one of the highest load capacities in its class at 715 lbs per tire, making it suitable for heavier trailers. The tread pattern is designed for highway use, and many owners report even wear over thousands of miles.
However, the bias-ply construction can transmit more road vibration, which may be less comfortable for long trips. If you prioritize a smoother ride or frequently tow at high speeds, a radial tire might be a better fit. But for durability and value, the K353 is a top contender.
- Bias-ply design with reinforced sidewalls for stability
- Deep tread pattern for long wear on paved roads
- Meets DOT safety standards
Pros: Excellent load capacity for its size; Durable construction with good puncture resistance
Cons: Stiffer ride compared to radial options
2. Carlisle Trail Wolf ST: Runner Up
Carlisle’s Trail Wolf ST radial tire stands out for its comfortable ride and heat management. Based on owner feedback, it tracks well at highway speeds and runs cooler than many bias-ply options, which can extend tire life. The radial construction also reduces rolling resistance, which may improve fuel efficiency slightly.
That said, its maximum load capacity is identical to the K353, but some owners note that the sidewalls feel less solid when fully loaded. If you carry near-maximum loads regularly, a bias-ply tire might offer more confidence. For most trailer applications, however, the Trail Wolf ST is an excellent choice.
- Radial construction for improved ride comfort
- Enhanced tread compound for heat resistance
- Built-in rim guard protects wheel from curb damage
Pros: Smoother ride than bias-ply tires; Good heat dissipation for highway use
Cons: Slightly less load capacity than some bias-ply rivals
3. Goodyear ST Special Trailer: Premium Pick
The Goodyear ST Special Trailer is a premium bias-ply tire that benefits from Goodyear’s engineering expertise. In our comparison of spec sheets, it offers the same load capacity as others but with a tread compound that resists cracking and ozone damage. Owners often praise its longevity on boat trailers and utility trailers that see moderate use.
However, the higher cost may not be justified for everyone, especially if you only need occasional use. Some users report that the tire is prone to dry rot if not stored properly. If you want a top-tier brand and are willing to pay a premium, this is a solid option; otherwise, you can get similar performance for less.
- Bias-ply with polyester cord body for strength
- Computer-optimized tread design for even wear
- Scuff-resistant sidewall treatment
Pros: Trusted brand with consistent quality; Good tread wear on paved surfaces
Cons: Higher price point than comparable tires
4. Taskmaster Premium ST: Best Value
The Taskmaster Premium ST is a budget-friendly bias-ply tire that delivers adequate performance for light to medium-duty trailers. Based on owner feedback, it holds up well for occasional use and provides good value for the price. The tread pattern is basic but functional for paved roads and light gravel.
However, some users note that the tires can feel stiff and may wear unevenly if not properly inflated. They are not ideal for heavy loads or frequent long-distance towing. If you have a small utility trailer or use it infrequently, this tire offers good bang for the buck.
- Bias-ply construction for affordability
- All-season tread pattern for varied conditions
- Meets DOT requirements
Pros: Very competitive price point; Decent tread life for the cost
Cons: Less refined ride quality
5. FreeStar ST Radial: Comfort Choice
The FreeStar ST Radial aims to provide the comfort of a radial tire at a lower price point. In our review of user feedback, many owners appreciate the reduced vibration and noise compared to bias-ply tires. The tread includes sipes that improve traction on wet roads, which is a plus for boat ramps.
However, some owners have reported sidewall bulges or premature failure, especially when overloaded. The durability does not match premium brands. If you prioritize ride comfort and drive mainly on paved surfaces, this tire is worth considering, but be cautious with load limits.
- Radial construction for smoother ride
- Tread design with sipes for wet traction
- Affordable radial option
Pros: Comfortable ride compared to bias-ply tires; Good wet grip
Cons: Sidewall durability concerns reported by some owners
6. Hercules Trail HD: Heavy Duty Option
The Hercules Trail HD is a load range D tire that offers a higher maximum capacity (790 lbs) than most 5.70-8 tires. This makes it suitable for heavier trailers or those that frequently carry near-maximum loads. The tread is deeper and more aggressive, providing better traction on unpaved surfaces.
However, the increased capacity comes with a stiffer ride and a higher price. Some owners note that the tire is overkill for light trailers and can feel harsh on the highway. If you need the extra load margin or frequently tow on gravel, this tire is a good choice; otherwise, a standard C range tire will suffice.
- Higher load range D for extra capacity
- Reinforced sidewalls for heavy loads
- Deep tread for off-road use
Pros: Higher load capacity than standard C range; Good for rough terrain
Cons: Stiff ride and higher price
7. EcoTrail ST Radial: Eco Friendly
The EcoTrail ST Radial markets itself as an environmentally friendly option, incorporating recycled materials and a design aimed at reducing rolling resistance. In theory, this could improve fuel economy, though the effect is minimal for trailers. Owners generally report a comfortable ride.
However, the trade-off appears to be durability. Several reviews mention tread wear faster than expected, and some have experienced sidewall issues. For those who prioritize eco-friendliness and tow light loads occasionally, this tire may appeal. But for long-term reliability, we recommend other options.
- Radial design with low rolling resistance
- Uses recycled materials in construction
- Tread pattern optimized for fuel efficiency
Pros: Environmentally conscious manufacturing; Smooth ride
Cons: Durability concerns; some owners report short tread life
Frequently Asked Questions
What does 5.70-8 mean on a trailer tire?
The 5.70-8 designation indicates the tire size: 5.70 is the approximate width in inches, and 8 is the rim diameter in inches. The hyphen indicates a bias-ply construction, though some modern tires use radial construction and may be labeled differently. This size is common on small to medium trailers.
Can I use a 5.70-8 tire on a 4.80-8 rim?
No, rim diameter must match. A 5.70-8 tire requires an 8-inch rim. The width difference (5.70 vs 4.80) may also require a different rim width. Always check your trailer’s rim specifications and the tire manufacturer’s recommended rim width range.
What is the difference between bias-ply and radial trailer tires?
Bias-ply tires have plies that run diagonally, offering stiffer sidewalls and higher load capacity at lower speeds. Radial tires have plies perpendicular to the tread, providing a smoother ride, better heat dissipation, and lower rolling resistance. For highway towing, radials are often preferred; for heavy loads at lower speeds, bias-ply may be better.
How do I determine the correct load range for my trailer?
Check your trailer’s GVWR (Gross Vehicle Weight Rating) and divide by the number of tires to find the required load capacity per tire. Then select a tire with a load range that meets or exceeds that capacity. Load Range C typically supports up to 715 lbs at 60 psi, while Load Range D supports up to 790 lbs at 65 psi.
How often should I replace 5.70-8 trailer tires?
Trailer tires should be replaced every 5 to 6 years regardless of tread depth, due to rubber aging. Also replace them if you see cracks, bulges, or excessive wear. Check tire pressure before each trip and inspect for damage regularly.
Our Verdict
After researching and comparing specs and owner feedback, the Kenda Loadstar K353 earns our top pick for its excellent load capacity, durability, and overall value. For those seeking a smoother ride, the Carlisle Trail Wolf ST is a strong runner-up with its radial construction and comfort. Both tires meet safety standards and have proven reliable across many trailer types.
