1. Goodyear Endurance Trailer Tire: Best Overall
The Goodyear Endurance is a top-tier trailer tire engineered for reliability. It features a heat-resistant tread compound and a scuff guard that protects the sidewall from abrasion. In our evaluation of manufacturer data and owner feedback, this tire consistently scores high for stability and low vibration, even when towing near its maximum load. The Load Range E construction provides a solid 2830-pound capacity at 80 psi, making it suitable for heavier trailers like boat trailers and campers.
However, the Endurance comes at a higher cost than many competitors, which may deter budget-conscious buyers. Some owners note that the ride can feel slightly stiff when unloaded. If you primarily tow light loads or on rough roads, you might find better value elsewhere. This tire is best for those who prioritize safety and longevity over upfront savings.
- Specifically designed for trailer use with sturdy sidewalls
- Heat-resistant tread compound reduces blowout risk
- Scuff guard helps protect against curb damage
Pros: Excellent stability at highway speeds; Long tread life reported by many owners
Cons: Premium price point
2. Carlisle Radial Trail HD: Runner Up
The Carlisle Radial Trail HD is a popular choice among trailer owners who want dependable performance without the premium price. It features a reinforced sidewall and a tread pattern designed to channel water away, reducing hydroplaning risk. Based on owner feedback and spec sheet analysis, this tire offers a smooth, quiet ride and handles highway speeds well. Its Load Range D rating supports up to 2540 pounds per tire at 65 psi, which is adequate for many tandem-axle trailers.
That said, the lower load capacity may be a limitation for heavy single-axle trailers or those carrying maximum loads. Some users report faster tread wear when consistently loaded near capacity. If you need the extra margin of a Load Range E tire, you might consider a higher-rated option. The Carlisle is ideal for moderate-duty towing where cost and performance are both priorities.
- Enhanced tread design for improved water evacuation
- Reinforced sidewalls for better load support
- Smooth and quiet ride on highways
Pros: Good balance of performance and price; Reliable in wet conditions
Cons: Slightly lower load capacity than Load Range E options
3. Maxxis M8008 ST Radial: Best Durability
The Maxxis M8008 is renowned for its rugged construction and long-lasting tread. It uses a cut-resistant compound that stands up to gravel and debris, making it a favorite for off-road or construction trailers. In our research, owner reviews frequently cite 5+ years of service with proper maintenance. The Load Range E rating matches the Goodyear Endurance at 2830 pounds, providing ample capacity for heavy loads.
However, the M8008 tends to produce more road noise than some competitors, which might be noticeable on long highway trips. Some owners also report occasional difficulty finding stock due to high demand. If you operate on rough terrain or need maximum toughness, this tire is an excellent choice. For those prioritizing a quiet ride, other options may be more suitable.
- Built with a tough, cut-resistant tread compound
- Sturdy sidewalls reduce flex and heat buildup
- Proven track record for long tread life
Pros: Exceptional durability and puncture resistance; High load capacity
Cons: Can be noisy on some surfaces; Limited availability at times
4. Kenda Karrier ST Radial: Best Value
The Kenda Karrier ST is a solid entry-level trailer tire that offers dependable performance at a budget-friendly price. It features a tread design aimed at stability and even wear. Based on aggregated owner feedback, it performs well for light to medium-duty applications such as small utility trailers or pop-up campers. The Load Range D capacity of 2540 pounds is sufficient for many single-axle trailers.
On the downside, some users report faster tread wear under heavy loads or high-speed highway use. The tire also lacks some of the advanced heat-dissipation features found in premium models. If you frequently tow near maximum capacity or in hot climates, you may want to invest in a higher-rated tire. The Kenda is best for budget-conscious buyers with lighter towing needs.
- Affordable price without sacrificing essential features
- Tread pattern designed for stable towing
- Lightweight design reduces unsprung weight
Pros: Very competitive pricing; Good for lighter trailers
Cons: Not as durable as premium options; Lower load capacity
5. Taskmaster Premium ST Radial: Good for Heavy Loads
The Taskmaster Premium ST is a value-oriented Load Range E tire that provides the high capacity needed for heavy trailers without the premium cost. It features a reinforced bead and a tread compound designed for durability. In our comparison, it offers a similar load rating to the Goodyear and Maxxis at a lower price, making it attractive for budget-minded owners with heavy towing needs.
However, owner feedback indicates that tread wear can be faster than expected, especially on long highway trips. Some users also note that tires may require careful balancing to avoid vibration. If you need maximum load capacity but are willing to accept a shorter lifespan, this tire could work. For those who prioritize longevity, spending more on a premium brand may be worthwhile.
- High load capacity for heavy trailers
- Reinforced bead area for improved stability
- Affordable Load Range E option
Pros: Cost-effective for Load Range E; Handles heavy loads well
Cons: Tread life shorter than premium brands; Some reports of imbalance
6. Westlake ST Radial: Budget Pick
The Westlake ST Radial is an entry-level tire designed for light-duty trailers used primarily at low speeds. It is a very affordable options in the 225/75R15 size, making it appealing for those on a tight budget or for trailers that see infrequent use. The Load Range D rating provides a 2540-pound capacity, which is adequate for small utility trailers or boat trailers under 5000 pounds gross.
However, this tire is not built for sustained highway speeds or heavy loads. Owner reports indicate that tread wear accelerates quickly under load, and the tire may run hot on long trips. Safety ratings are lower than more durable options. If you only tow short distances at moderate speeds, the Westlake can save money. For regular highway towing, we recommend a higher-quality tire.
- Very low price point
- Suitable for light-duty trailers
- Basic tread design for straight-line stability
Pros: Extremely affordable; Adequate for occasional use
Cons: Limited tread life; Not recommended for highway speeds
7. Ironman All Country ST: All-Terrain Option
The Ironman All Country ST is designed for trailers that venture off paved roads. Its aggressive tread provides traction on gravel, dirt, and soft surfaces, making it a niche choice for off-road campers or utility trailers. The Load Range D construction offers reasonable capacity for moderate loads. Owner feedback highlights its ability to handle rough terrain without sidewall damage.
However, this tire is not optimized for highway use. It produces significant road noise and may wear quickly on asphalt. The speed rating is lower than standard ST tires, so sustained high-speed travel is not recommended. If your towing is primarily off-road or on unpaved roads, this tire can be a good fit. For highway towing, choose a more conventional radial.
- Aggressive tread pattern for off-road traction
- Reinforced sidewalls for puncture resistance
- Good for gravel and dirt roads
Pros: Decent off-road capability; Unique look
Cons: Noisy on pavement; Lower highway speed rating
Frequently Asked Questions
What is the difference between Load Range D and Load Range E in 225/75R15 trailer tires?
Load Range D tires have a maximum inflation pressure of 65 psi and a load capacity of 2540 pounds per tire, while Load Range E tires are rated at 80 psi and 2830 pounds. The higher pressure and capacity in Load Range E provide a greater safety margin for heavy loads but may result in a firmer ride. Choose Load Range E for heavier trailers or when towing near maximum capacity; Load Range D is sufficient for lighter loads.
Can I use passenger or light truck tires on my trailer instead of ST tires?
It is not recommended. ST (Special Trailer) tires are built with stronger sidewalls and reinforced construction to handle the unique stresses of trailer towing, including higher loads and lateral forces. Passenger or light truck tires lack these reinforcements and are more prone to failure, especially at highway speeds. Always use ST-rated tires for trailer applications to ensure safety and compliance.
How often should I replace 225/75R15 trailer tires?
Trailer tires should be replaced every 5 to 6 years regardless of tread depth, as rubber degrades over time. Additionally, replace them if you see signs of dry rot, cracking, bulges, or irregular wear. Check the DOT date code to determine age. Even if tread looks good, tires older than 6 years should be replaced for safety.
What is the proper inflation pressure for 225/75R15 trailer tires?
Inflate to the pressure listed on the tire sidewall, which is the maximum cold pressure. For Load Range D, that is typically 65 psi; for Load Range E, 80 psi. Always check pressure when tires are cold and before towing. Underinflation causes heat buildup and increases blowout risk, while overinflation reduces traction and ride comfort.
Can I use 225/75R15 tires on a 15×6 rim?
Yes, 225/75R15 tires are designed to fit rims with widths ranging from 6 to 7 inches. A 15×6 rim is within the approved range, but always verify the rim width specification from the tire manufacturer. Using a rim that is too narrow or too wide can affect tire performance and safety.
Our Verdict
After researching manufacturer specifications and owner feedback, the Goodyear Endurance earns our top pick for its excellent stability, heat resistance, and overall reliability. The Carlisle Radial Trail HD is a strong runner up, offering a great balance of performance and value for moderate-duty towing.
