1. Carlisle Radial Trail HD Trailer Tire: Best Overall for Heavy Loads
The Carlisle Radial Trail HD is a top choice for heavy-duty trailers like boat and enclosed car trailers. In our evaluation, its steel-belted radial construction provides superior stability at highway speeds and reduces heat buildup, which is critical for long trips. Owner feedback consistently praises its long tread life and resistance to wear. The stone ejector tread pattern is a thoughtful addition that minimizes puncture risks on gravel roads.
However, this tire is overkill for light utility trailers that rarely see highway speeds. Its higher cost and stiffer sidewall may not be ideal for those who need a spare only for occasional emergencies. If your trailer is lightweight and mostly used locally, a bias-ply spare might be more cost-effective.
- Steel-belted radial construction for highway stability and reduced heat buildup.
- Tread design with stone ejectors to prevent stone drilling.
- M+S rated for light mud and snow traction.
Pros: Excellent load capacity and durability for heavy trailers.; Smooth ride and low vibration compared to bias-ply tires.
Cons: Higher price point than bias-ply alternatives.
2. Goodyear Endurance Trailer Tire: Best for High Speed Stability
The Goodyear Endurance is our pick for those who frequently tow at highway speeds. Its heat-resistant compound and robust sidewall design make it a reliable spare for long trips. Based on owner feedback, this tire handles well in wet conditions and resists blowouts better than many competitors. We found its load capacity ratings consistent with advertised specs.
However, the Endurance is not available in smaller diameters like 12 or 13 inches, which limits its use for compact trailers. Also, the price is premium, so budget-conscious buyers may look elsewhere. If your trailer wheels are 14 inches or larger and you value peace of mind at 65 mph, this is a strong contender.
- Durawall technology for enhanced sidewall durability and curb scuff resistance.
- Heat-resistant compound for high-speed towing.
- Tread pattern with multi-wave sipes for wet traction.
Pros: Excellent high-speed stability and heat dissipation.; Strong sidewall protection against road debris.
Cons: Limited size availability for smaller trailers.
3. Kenda Loadstar K353 Trailer Tire: Best Budget Pick
The Kenda Loadstar K353 is a budget-friendly bias-ply tire that works well for utility and small boat trailers. In our evaluation, it offers solid load capacity for its size and the deep tread provides good traction on unpaved surfaces. Owner reviews highlight its value for money and resistance to punctures in off-road conditions.
However, bias-ply tires generate more heat at highway speeds, making them less suitable for long-distance towing. The ride can be stiffer and vibration more noticeable. If you primarily tow locally or at lower speeds, this is a great spare. But for frequent highway use, we recommend a radial tire.
- Bias-ply construction for affordability and durability on rough roads.
- Deep tread depth for longer wear.
- Reinforced sidewalls to resist cuts and abrasions.
Pros: Very affordable spare option for light to medium trailers.; Durable bias-ply design handles rough terrain well.
Cons: Bias-ply tires run hotter and are less stable at highway speeds.
4. Maxxis M8008 ST Radial Trailer Tire: Best for Longevity
The Maxxis M8008 is renowned for its longevity, making it a favorite among RV and boat owners who need a spare that can double as a daily tire. We researched owner forums and found consistent praise for its tread life, often exceeding 30,000 miles under proper inflation. The radial construction provides good heat dissipation and stability.
However, the M8008 is a premium tire and may be overkill for a spare that rarely gets used. Its high load capacity is excellent, but if your trailer is light, you might be paying for capacity you don’t need. Consider this if you want a spare that can be rotated into regular service.
- Radial construction with twin steel belts for long tread life.
- Scrub-resistant sidewall compound for durability.
- Tread pattern optimized for even wear and reduced noise.
Pros: Exceptional tread life and even wear reported by owners.; Stable and quiet ride on highways.
Cons: Premium pricing; not the cheapest option.
5. Taskmaster Premium ST Trailer Tire: Best Value Radial
The Taskmaster Premium ST offers a radial tire experience without the high cost, making it a smart choice for small utility and landscape trailers. In our evaluation, its radial design provides a smoother ride and better heat management than bias-ply tires in the same price range. Owner feedback notes that it fits most 12-inch rims easily.
However, its load capacity is limited, so it is not suitable for heavy boats or large campers. Some users reported faster tread wear under heavy loads. If your trailer is lightweight and you want a radial spare on a budget, this is a good pick. Otherwise, consider a higher capacity tire.
- Radial construction at a budget-friendly price.
- All-season tread compound for varied conditions.
- Lightweight and easy to mount.
Pros: Affordable radial option for small trailers.; Good value for the price compared to bias-ply alternatives.
Cons: Lower load capacity may not suit heavier trailers.
6. Carlisle Sport Trail LH Trailer Tire: Best for Boat Trailers
The Carlisle Sport Trail LH is a common spare for boat trailers due to its affordability and adequate load capacity for many smaller boats. We compared its specs to industry standards and found it meets basic requirements. Owners appreciate its lightweight design, which makes it easy to store under the trailer.
However, this tire is bias-ply and not recommended for sustained highway speeds. It can overheat on long trips. Also, the load range B limits its use to lighter trailers. If you tow a heavy boat or drive long distances, look for a radial spare. For short local trips, it gets the job done.
- Bias-ply construction with polyester cord for flexibility.
- Rib tread design for stable tracking.
- Lightweight and easy to store.
Pros: Affordable spare for boat trailers.; Decent stability for moderate speeds.
Cons: Not intended for highway speeds; bias-ply heat buildup.
7. Wheel Master ST205/75R15 Trailer Tire: Best for Heavy Duty Utility
The Wheel Master ST is a heavy-duty bias-ply tire designed for utility trailers that carry heavy loads like equipment or landscaping materials. We researched its load specs and found it matches many radial competitors in capacity. Owner feedback indicates it holds up well on rough roads and resists punctures.
However, being bias-ply, it is less comfortable on highways and prone to heat buildup. It is best suited for short trips or off-road use. If you need a spare for a trailer that rarely sees highway speeds, this is a solid choice. For regular highway towing, upgrade to a radial.
- Bias-ply construction with heavy-duty nylon cord.
- Deep tread for traction on loose surfaces.
- Reinforced bead area for mounting durability.
Pros: High load capacity for a bias-ply tire.; Good traction on gravel and dirt.
Cons: Bias-ply design leads to higher vibration and heat.
Frequently Asked Questions
What is the difference between ST and LT tires for trailers?
ST (Special Trailer) tires are designed specifically for trailers, with stronger sidewalls and higher load capacities at lower inflation pressures. LT (Light Truck) tires are for trucks and SUVs and may not handle the lateral forces of trailer towing as well. For a spare, always use an ST tire unless your trailer manufacturer specifies otherwise.
How do I choose the right spare tire size for my trailer?
Check the sidewall of your existing tires for the size code (e.g., 205/75R15). The spare should match this exactly in diameter, width, and load range. Also verify the bolt pattern and offset of your trailer’s hub. If unsure, consult your trailer’s owner manual or a tire professional.
Can I use a car tire as a spare for my trailer?
No, car tires are not designed for the loads and stresses of trailer towing. They lack the reinforced sidewalls and load capacity of ST tires. Using a car tire as a spare can lead to blowouts and safety hazards. Always use a tire rated for trailer use.
How should I store a spare trailer tire?
Store the spare in a cool, dry place away from direct sunlight and ozone sources like electric motors. Keep it mounted on a rim or lay it flat to prevent distortion. Check tire pressure every few months and maintain it at the recommended psi.
What is the maximum speed rating for trailer spare tires?
Most ST tires have a speed rating of 65 mph (N speed rating) or 75 mph (P rating). Always check the sidewall for the speed symbol. For highway towing, do not exceed the tire’s rated speed. Some radial tires like the Goodyear Endurance have higher ratings.
