1. Goodyear Endurance ST: Top Pick
The Goodyear Endurance ST is a top performer in our research, consistently praised by owners for its stability at highway speeds and resistance to heat-related failures. Its special tread compound and robust sidewall design meet or exceed industry standards for trailer tires. Based on owner feedback and the spec sheets, it delivers reliable performance for heavy loads and long distances.
However, the Endurance ST commands a higher price than many competitors, which may not suit budget-conscious buyers. If you only tow occasionally at lower speeds, a more affordable option might suffice. It’s best for those who frequently tow heavy loads on highways and prioritize safety and longevity.
- Advanced tread compound reduces heat buildup for high-speed stability
- Reinforced sidewalls resist cuts and abrasion from road debris
- Strong warranty and nationwide service network support
Pros: Excellent heat dissipation for long hauls; Durable construction with steel belts
Cons: Premium price point
2. Maxxis M8008 ST Radial: Runner Up
The Maxxis M8008 ST has earned a loyal following among trailer owners for its dependable performance and competitive pricing. Our research shows it offers stable towing and good tread life when properly inflated. Owner feedback highlights its durability on varied road surfaces, and its nylon construction provides a smoother ride than stiffer steel-belted tires.
That said, the M8008 may not be the best choice for very heavy loads or extreme high-speed towing, as it lacks the steel belts found on some premium models. If you frequently tow near maximum capacity or at sustained highway speeds, consider a load range E tire. It is ideal for moderate-duty trailers and budget-minded buyers.
- Stable handling and reduced sway even at maximum load
- Nylon cord body absorbs road shocks and resists aging
- Backed by a strong manufacturer warranty
Pros: Good balance of price and performance; Proven reliability in the trailer community
Cons: Not as heat resistant as some steel-belted rivals
3. Carlisle Radial Trail HD: Best Value
The Carlisle Radial Trail HD offers a cost-effective solution for trailer owners who need reliable tires without breaking the bank. Our evaluation shows it meets basic safety standards and performs adequately for typical towing needs. Owner reviews often mention satisfaction with its handling and ride comfort, especially for boat and utility trailers.
However, the Radial Trail HD may wear faster under heavy loads or frequent high-speed use, and its polyester cord construction is less robust than steel or nylon alternatives. If you tow heavy loads regularly or demand maximum durability, you might prefer a higher-tier option. This tire is best for light to moderate use where budget is a primary concern.
- Affordable price without sacrificing essential safety features
- All-season tread pattern provides good traction in wet conditions
- Lightweight design improves fuel economy and reduces unsprung weight
Pros: Excellent value for the price; Good wet traction
Cons: Tread life may be shorter than premium competitors
4. Kenda Loadstar K399 ST: Heavy Duty Choice
The Kenda Loadstar K399 ST is built for heavy-duty towing, with steel belts and a high load rating that inspire confidence. Our research indicates it performs well under extreme loads and is a favorite among owners of large travel trailers and flatbed trailers. The deep tread pattern contributes to long wear, and the tire meets DOT standards for safety.
On the downside, the stiff construction can make the ride feel harsh, especially on rough roads, and some owners report increased road noise. If you prioritize ride comfort over load capacity, this may not be the best choice. It is ideal for those who consistently tow near the maximum weight rating and need a tire that can handle the strain.
- High load capacity with reinforced steel belts
- Deep tread pattern for long tread life
- Sturdy sidewalls resist impact damage
Pros: Excellent load-carrying capability; Durable steel-belted construction
Cons: Ride can be stiff and transmit road vibrations
5. Taskmaster Premium ST Radial: Budget Friendly
The Taskmaster Premium ST Radial is an entry-level tire that meets minimum safety requirements for light trailer applications. Our research shows it is best suited for small utility trailers, lawn equipment trailers, or occasional use. Owner feedback indicates it performs adequately at moderate speeds and loads, but it is not designed for heavy or frequent towing.
However, this tire has significant limitations: a lower load range and speed rating mean it is not safe for heavy loads or highway speeds. If you plan to tow heavy loads or travel long distances, we recommend a higher-rated tire. This option is only for budget-constrained buyers with very light towing needs.
- Low initial cost for entry-level buyers
- Suitable for light-duty trailers and occasional use
- Basic tread design provides adequate traction on dry pavement
Pros: Very affordable; Lightweight and easy to install
Cons: Limited load capacity and lower speed rating
6. Hercules Trail-Trac ST Radial: All-Terrain Option
The Hercules Trail-Trac ST Radial is designed for trailers that venture off the beaten path, such as off-road campers or utility trailers used on construction sites. Our research shows its tread pattern provides improved traction on loose surfaces compared to typical highway ST tires. Owner reviews appreciate its capability on gravel and dirt roads.
That said, the aggressive tread leads to higher noise on paved roads and accelerated wear during highway use. If most of your towing is on pavement, a standard ribbed tire will be quieter and last longer. This tire is best for those who frequently tow on unpaved surfaces and are willing to compromise on-road manners.
- Aggressive tread pattern for off-road traction
- Reinforced shoulder blocks resist cuts
- Good for boat ramps and gravel roads
Pros: Better off-road grip than standard ST tires; Affordable for an all-terrain design
Cons: Increased road noise and faster wear on pavement
7. Deestone D404 ST Radial: Economy Pick
The Deestone D404 ST Radial is the most budget-friendly option in our research, aimed at owners of small, lightweight trailers used for short trips. It meets the minimum DOT requirements and can be a suitable spare or replacement for very light loads. Owner feedback notes it is adequate for moving a small boat or utility trailer around town.
However, this tire should not be used for heavy loads or highway speeds, as its load range C and nylon construction offer limited safety margins. If you need a tire for anything beyond occasional light use, we strongly advise investing in a higher-rated model. This tire is only for the most cost-sensitive buyers with minimal towing demands.
- Very low price point
- Basic construction for light-duty trailers
- Available in many common sizes
Pros: Extremely affordable; Wide size availability
Cons: Lowest load capacity and speed rating in this guide
Frequently Asked Questions
What does ST mean on a trailer tire?
ST stands for Special Trailer. ST tires are designed specifically for trailers, with stronger sidewalls and higher load capacities than passenger car tires. They are built to handle the lateral forces and heat generated during towing.
Can I use passenger car tires on my trailer?
No, it is not recommended. Passenger car tires (P-metric) have weaker sidewalls and are not designed for the constant load and stress of towing. Using them can lead to tire failure and safety hazards. Always use ST tires for trailers.
What is load range and why is it important?
Load range indicates the tire’s maximum load capacity and inflation pressure. Higher letters (e.g., C, D, E) correspond to higher capacity. Choosing the correct load range ensures your tire can safely support the trailer’s weight and reduces risk of blowouts.
How often should I replace trailer tires?
Trailer tires should be replaced every 5 to 6 years regardless of tread depth, due to age-related degradation. Also replace them if you see cracks, bulges, or excessive wear. Regularly inspect pressure and condition before each trip.
What is the proper tire pressure for ST tires?
Always follow the pressure molded on the sidewall, not the vehicle’s door sticker. Inflate to the maximum pressure listed when cold for the rated load capacity. Underinflation causes heat buildup and can lead to tire failure.
Our Verdict
After researching specifications, safety standards, and owner feedback, our top pick is the Goodyear Endurance ST for its superior heat management and durability, especially for heavy loads and highway use. The Maxxis M8008 ST is an excellent runner-up, offering reliable performance at a more accessible price point for moderate-duty towing.
