1. Carlisle Radial Trail HD: Best Overall
In our evaluation, the Carlisle Radial Trail HD stands out as a top performer. It features a radial ply construction that runs cooler and provides better stability than bias-ply tires, making it ideal for longer highway trips. Owner feedback consistently praises its durability and even wear. The tire meets DOT standards and carries a Load Range D rating, supporting up to 1,900 lbs per tire at 65 psi. We found that many users report getting several seasons of heavy use without significant tread loss.
However, the Radial Trail HD is not the most budget-friendly option. If you only tow short distances at lower speeds, a bias-ply tire may offer similar reliability for less. Additionally, some owners have noted that the tire can be prone to sidewall cracking if exposed to UV for extended periods, so proper storage is important. This tire is best for those who prioritize highway performance and long-term durability over initial cost.
- Radial construction for improved stability and heat dissipation
- Excellent tread wear and resistance to aging
- Smooth towing at highway speeds
Pros: Long tread life based on owner reports; Good heat resistance for highway use
Cons: Premium price point
2. Goodyear Endurance: Premium Pick
The Goodyear Endurance is a premium trailer tire that we researched extensively. It features a specialized steel belt package and a scuff guard that helps resist damage from curbs and debris. Owner reviews often highlight its confidence-inspiring handling at highway speeds. In our comparison of spec sheets, it offers a load capacity of 1,870 lbs per tire, just slightly below the Carlisle, but with a focus on puncture resistance.
That said, the Endurance comes at a premium price, and some owners have reported that the tread life is not significantly better than mid-range options for light-duty use. If you primarily tow a lightweight trailer locally, the extra cost may not be justified. Also, a few users have mentioned that the tire can feel stiff on rough roads. This tire is best for those who frequently tow heavy loads at highway speeds and want maximum puncture protection.
- Enhanced steel belt construction for puncture resistance
- Scuff guard to protect sidewalls
- Designed for high-speed stability
Pros: Strong sidewall protection; Good high-speed performance
Cons: Higher cost than many competitors
3. Taskmaster Premium ST: Best Value
The Taskmaster Premium ST is a budget-friendly bias-ply tire that we evaluated as a solid value for light-duty applications. With a Load Range C rating and 1,360 lbs capacity, it suits smaller utility trailers or boat trailers that aren’t heavily loaded. Owner feedback indicates that it performs well at speeds under 55 mph and provides a decent ride for the price. The tire’s simple construction keeps costs low while still meeting safety standards.
However, this tire has clear limitations. Bias-ply tires generate more heat at higher speeds, so they are not suitable for long highway trips. Some owners have reported uneven wear if not properly inflated. If you need to tow heavy loads or travel at highway speeds regularly, you should invest in a radial tire. The Taskmaster is best for occasional, low-speed use where budget is a primary concern.
- Bias-ply construction for affordability
- Good for low-speed, short-distance towing
- Meets DOT standards
Pros: Very affordable; Reliable for light-duty use
Cons: Lower load capacity; Not recommended for highway speeds
4. Kenda Karrier ST Radial: Solid Performer
The Kenda Karrier ST Radial is a popular choice that we researched as a middle-ground option. It offers a Load Range D radial design at a price lower than Carlisle or Goodyear. Owner reviews often mention satisfactory highway stability and tread wear. In spec comparisons, it matches the load capacity of premium tires, making it a viable alternative for those on a tighter budget.
However, we found a notable number of owner reports mentioning sidewall bubbles or premature failure, though this may be due to overloading or improper inflation. The tire also tends to be slightly noisier than premium radials. If you are towing near the maximum load capacity frequently, you might want to opt for a more robust tire. The Karrier is best for moderate-duty towing where you want radial performance without the highest price.
- Radial construction for stability
- Good tread life in mixed conditions
- Competitive price for a radial
Pros: Good balance of performance and cost; Widely available
Cons: Some reports of sidewall bubbles; Not as refined as premium brands
5. Westlake ST Radial: Budget Radial
The Westlake ST Radial is an entry-level radial tire that we evaluated for budget-conscious buyers. It provides the benefits of radial construction like better heat dissipation and a smoother ride compared to bias-ply tires, but at a lower cost. Owner feedback generally highlights it as a decent option for lightweight trailers used around town. The Load Range C rating limits its use to lighter loads.
On the downside, the Westlake’s tread life is often reported as shorter than more expensive radials, and some users have experienced cupping or irregular wear. It is not designed for heavy or high-speed use. If you frequently tow near its capacity or on highways, this tire may disappoint. It is best for those who need a radial tire for occasional light-duty towing and want to minimize expense.
- Affordable radial option
- Suitable for light trailers
- Good for local towing
Pros: Low price for a radial; Smoother ride than bias-ply
Cons: Lower load capacity; Tread life can be shorter
6. SureTrac ST Radial: Mid-Range Option
The SureTrac ST Radial sits in the middle of our researched options. It offers radial construction and a Load Range C rating, making it suitable for light to moderate towing. Owner reviews are mixed but generally positive for the price point. We found that many users appreciate its stability on the highway when not overloaded. The tire meets basic DOT safety standards.
However, the SureTrac has a reputation for inconsistent quality; some owners report good longevity while others experience early wear or vibration. It also has a lower load capacity than Load Range D tires. If you need to carry heavier loads or want maximum reliability, you should look at higher-rated options. This tire is best for budget-minded owners with light trailers who are willing to accept some variability.
- Radial design at a moderate price
- Decent highway stability for light loads
- DOT approved
Pros: Good value for the price; Acceptable highway performance
Cons: Average durability; Some balance issues reported
7. Trailer King ST Radial: Economy Pick
The Trailer King ST Radial is the most economical tire we researched. It is available in both bias-ply and radial versions; we evaluated the radial. It provides the basics: it holds air and meets minimum DOT standards. Owner feedback often describes it as a tire that gets the job done for very occasional, low-speed use around the farm or neighborhood. The price is hard to beat.
However, the Trailer King has significant drawbacks. Many owners report rapid tread wear, even with light use, and some have experienced blowouts when pushed beyond gentle conditions. The Load Range C limits its capacity, and the tire is not designed for sustained highway speeds. If you tow frequently, at higher speeds, or with heavier loads, this tire is not suitable. It is best for those who need a cheap spare or use their trailer only a few times a year on back roads.
- Lowest cost option in our comparison
- Bias-ply or radial available (radial evaluated)
- Basic trailer use
Pros: Extremely affordable; Works for short trips
Cons: Short tread life; Not for highway or heavy loads
Frequently Asked Questions
What does 175/80R13 mean for a trailer tire?
The numbers indicate tire size: 175 is the width in millimeters, 80 is the aspect ratio (sidewall height as a percentage of width), and R13 means radial construction with a 13-inch rim diameter. For trailer tires, the ‘ST’ stands for Special Trailer, meaning the tire is designed specifically for trailer use with stronger sidewalls and higher load capacity than passenger tires.
What is load range and why does it matter?
Load range indicates the tire’s ply rating and maximum load capacity at a given inflation pressure. Common ranges for 175/80R13 trailer tires are C (6-ply, 1,360 lbs) and D (8-ply, 1,870 lbs). Choosing the correct load range ensures the tire can safely support your trailer’s weight, including cargo. Under-rating can lead to tire failure.
Can I use passenger car tires on my trailer?
No, it is not recommended. Trailer tires (ST) have reinforced sidewalls and tread compounds designed for the constant load and stress of towing. Passenger car tires (P-metric) lack these features and are more prone to failure under trailer loads, especially at highway speeds. Always use ST-rated tires for trailers.
How do I know what tire pressure to use?
Always follow the pressure molded on the tire sidewall, not the vehicle’s door sticker. For maximum load capacity, inflate to the maximum psi listed (typically 50 psi for Load Range C, 65 psi for Load Range D). Check pressure when tires are cold and before each trip. Proper inflation is critical for safety and tire life.
How often should I replace trailer tires?
Trailer tires should be replaced every 5 to 6 years regardless of tread depth, due to rubber aging and UV degradation. Inspect them annually for cracks, bulges, or uneven wear. If you tow frequently, replace them sooner if signs of wear appear. Never use a tire that is more than 10 years old.
Our Verdict
After researching and comparing the top 175/80R13 trailer tires, our top pick is the Carlisle Radial Trail HD for its excellent highway stability, long tread life, and high load capacity. It is the best balance of performance and durability for most trailer owners. For a more budget-friendly option that still offers good reliability, the Taskmaster Premium ST is our runner-up, ideal for light-duty, low-speed towing where cost is a primary concern.
