1. Kenda Karrier ST205/75R15: Best Overall
The Kenda Karrier ST205/75R15 is a top choice for boat and utility trailers. In our evaluation, it consistently meets load ratings and shows minimal tread wear even after extended use. Owner feedback highlights its stability at highway speeds, though it is not rated for speeds above 65 mph.
However, this tire is not ideal for heavy-duty commercial trailers exceeding 10,000 lbs GVWR. If you need a higher speed rating or all-steel construction, consider a different model. It performs best on single-axle trailers under moderate loads.
- Durable bias-ply construction for highway towing
- Reinforced sidewalls reduce sway and blowouts
- Tread design promotes even wear and long life
Pros: Excellent load capacity for its size; Good tread life reported by owners
Cons: Not suitable for speeds above 65 mph
2. Carlisle Radial Trail HD ST225/75R15: Runner Up
The Carlisle Radial Trail HD is a premium radial trailer tire. Our research shows it outperforms many bias-ply tires in heat dissipation and ride comfort. Owner reviews praise its stability when towing heavy loads, and the 10-ply rating gives confidence for larger trailers.
That said, the higher price may not be justified for light-duty trailers used occasionally. If you only tow short distances at low speeds, a bias-ply tire could be more cost-effective. Also, some owners reported difficulty finding proper inflation for optimal wear.
- Radial construction for smoother ride and less heat buildup
- High load capacity suitable for heavy trailers
- Stable handling even in crosswinds
Pros: Higher speed rating (up to 81 mph); Long tread life warranty
Cons: More expensive than bias-ply alternatives
3. Goodyear Endurance ST225/75R15: Premium Choice
The Goodyear Endurance is engineered for serious towing. In our comparison, it stands out for its all-steel casing and robust construction. Owner feedback frequently mentions confidence on long highway trips and reduced blowout risk. It carries a strong warranty and is a top pick for RV owners.
However, the cost is significantly higher than many competitors. For occasional or light-duty use, the investment may not pay off. Also, some users noted that the tire runs slightly harder, transmitting more road vibration to the trailer.
- All-steel construction for maximum puncture resistance
- Enhanced tread compound for longer wear
- Engineered for high-speed stability
Pros: Excellent puncture resistance; Great for long-distance towing
Cons: Premium price point
4. Taskmaster Premium ST205/75R14: Best Value
The Taskmaster Premium ST205/75R14 is a solid budget-friendly choice for lighter trailers. Our research indicates it meets basic safety standards and owner reviews highlight its value for the price. It works well for single-axle trailers under 3,500 lbs.
However, its 6-ply rating and lower speed limit (65 mph) make it unsuitable for heavy loads or highway travel. If you tow frequently or carry near capacity, step up to a Load Range D or E tire. Some owners also reported faster tread wear under heavy use.
- Affordable bias-ply option for light trailers
- Good tread design for water evacuation
- Meets DOT standards
Pros: Very budget-friendly; Suitable for small boat and utility trailers
Cons: Lower load capacity and speed rating
5. Maxxis M8008 ST235/80R16: Heavy Duty
The Maxxis M8008 is built for the heaviest trailers, such as large horse trailers or equipment haulers. In our evaluation, its 14-ply rating and high load capacity are unmatched among ST tires. Owner feedback from commercial users is positive, citing long tread life under constant heavy loads.
However, this tire is overkill for most recreational trailers. The high cost and need for 110 psi inflation (requiring a compressor) are significant drawbacks for casual users. It also rides stiffer, which may not be ideal for sensitive cargo.
- Extremely high load capacity for large trailers
- Steel-belted radial for durability
- Designed for commercial and heavy hauling
Pros: Handles very heavy loads; Robust construction
Cons: Very expensive; Requires high inflation pressure
6. Power King Towmax STR ST205/75R15: Budget Pick
The Power King Towmax STR is the most economical option we researched. It is adequate for very light trailers used at low speeds, such as small utility trailers. Owner reviews are mixed, with many appreciating the low cost but some reporting early wear or balance issues.
This tire is not suitable for heavy loads or frequent towing. If you need a reliable primary tire for highway use, we recommend spending more for a higher-ply option. It may serve well as a spare in a pinch, but expect limited service life.
- Lowest price point in our comparison
- Basic bias-ply design for light-duty use
- Available in common sizes
Pros: Very affordable; Good for spare tire use
Cons: Lower durability and shorter tread life; Not recommended for highway speeds
7. Greenball Towmaster ST225/75R15: Off-Road Option
The Greenball Towmaster is designed for trailers that venture off paved roads, such as off-road campers or utility trailers on construction sites. Our research shows its tread pattern provides superior grip in mud and gravel compared to standard highway tires. Owner feedback from off-road users is positive regarding durability.
However, the aggressive tread results in increased road noise and faster wear on pavement. It also has a lower speed rating (65 mph) and may not be the best choice for long highway trips. If you primarily tow on roads, a smoother tire would be more suitable.
- Aggressive tread for off-road traction
- Reinforced sidewalls for rocky terrain
- Bias-ply construction for durability
Pros: Good traction on loose surfaces; Sturdy build
Cons: Noisy on pavement; Lower speed rating
Frequently Asked Questions
What is the difference between bias-ply and radial trailer tires?
Bias-ply tires have layers of cords running diagonally, making them stiffer and more resistant to sidewall damage, ideal for heavy loads at lower speeds. Radial tires have cords running perpendicular to the tread, offering a smoother ride, better heat dissipation, and higher speed ratings. For highway towing, radials are generally preferred; for off-road or heavy loads, 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 the tire’s maximum load capacity at a given pressure. The sum of all tire load capacities must exceed the GVWR. Load ranges (C, D, E, etc.) indicate ply rating and maximum pressure. Use at least Load Range C for light trailers, D for medium, and E or higher for heavy trailers. Always inflate to the pressure listed on the tire sidewall.
Can I use passenger car tires on my trailer?
No. Passenger car tires (P-metric) are not designed for the higher loads and sidewall stresses of trailering. They can overheat and fail. Always use Special Trailer (ST) tires, which have stronger sidewalls and higher load capacities. For larger trailers, LT (Light Truck) tires may be acceptable if load ratings are sufficient, but ST tires are recommended by manufacturers.
How often should I replace trailer tires?
Trailer tires should be replaced every 5-7 years regardless of tread depth, due to rubber aging and UV damage. Also replace if you see cracks, bulges, or excessive wear. Check tire pressure before every trip and inspect for damage. Many experts recommend replacing after 6 years even if tread looks good.
What size rim do I need for my trailer tire?
The rim diameter must match the tire diameter (e.g., 15-inch tire needs a 15-inch rim). The rim width should be within the tire’s approved range, usually stamped on the tire sidewall or in the owner’s manual. Common sizes for trailer tires are 14, 15, and 16 inches. Always match the bolt pattern (e.g., 5 on 4.5 inches) to your trailer hub.
Our Verdict
After researching and comparing specifications and owner feedback, the Kenda Karrier ST205/75R15 earns our top pick for its reliable performance, strong load capacity, and good value. For those needing a higher speed rating and radial ride, the Carlisle Radial Trail HD is an excellent runner up. Choose based on your trailer’s weight and typical usage.
