Buyer’s Guide: How to Choose the Best Trailer Tire
Choosing the right trailer tire is one of the most important decisions you can make for safe towing. Unlike passenger vehicle tires, Special Trailer (ST) tires are engineered with stronger sidewalls and higher load capacities to handle the unique demands of towing. Selecting the correct tire can improve stability, reduce trailer sway, and help prevent tire failures on the road.
Choose the Correct Tire Size
Always replace your trailer tires with the size recommended by the trailer manufacturer or listed on the tire sidewall. Using the wrong tire size can affect load capacity, handling, and overall towing safety.
Understand Load Range
Load range indicates how much weight a tire is designed to carry. Common trailer tire load ranges include:
- Load Range C – Light-duty utility trailers
- Load Range D – Medium-duty utility and cargo trailers
- Load Range E – Heavy-duty utility, enclosed, and equipment trailers
- Load Range G – Commercial equipment and heavy-haul trailers
Choose a tire with a load capacity that exceeds the maximum loaded weight your trailer axle will carry.
Radial vs. Bias Ply Tires
Most trailer owners should choose radial tires because they provide:
- Longer tread life
- Better highway performance
- Reduced heat buildup
- Improved fuel efficiency
- Smoother ride
Bias-ply tires are still useful for certain off-road or agricultural applications but are less common for everyday highway towing.
Check the Speed Rating
Modern trailer tires have different speed ratings. If you regularly travel on highways, select a tire that is rated for the speeds you expect to drive. Exceeding a tire’s speed rating can increase heat buildup and shorten its lifespan.
Inspect Tires Regularly
Before every trip, inspect your trailer tires for:
- Low air pressure
- Uneven tread wear
- Sidewall cracks
- Bulges or cuts
- Nails or other punctures
Maintaining the correct tire pressure is one of the easiest ways to improve tire life and towing safety.
Replace Aging Tires
Even if your trailer tires still have plenty of tread, rubber naturally ages over time. Many manufacturers recommend replacing trailer tires after several years of service, especially if they show signs of weather cracking or have been exposed to harsh outdoor conditions.
Rotate and Maintain Your Tires
While trailer tires generally wear more evenly than vehicle tires, rotating tandem-axle trailer tires and maintaining proper wheel alignment can help maximize tread life and improve overall towing performance.
Choosing the right trailer tire is about more than price. Selecting the proper size, load range, and construction for your trailer will improve safety, reduce maintenance, and give you greater confidence every time you tow.
Frequently Asked Questions
What does ST mean on a trailer tire?
ST stands for Special Trailer. ST tires are specifically designed for trailers and feature stronger sidewalls, higher load capacities, and improved stability compared to passenger or light truck tires. They are the recommended choice for most utility, boat, cargo, RV, and equipment trailers.
How often should trailer tires be replaced?
Even if the tread still looks good, most trailer tires should be replaced every 5 to 7 years, depending on their condition, usage, and storage. Regularly inspect your tires for cracks, dry rot, uneven wear, and other signs of aging.
What tire pressure should I run in my trailer tires?
Always inflate your trailer tires to the pressure listed on the tire sidewall or recommended by the trailer manufacturer. Proper tire pressure helps maximize load capacity, improve tire life, and reduce the risk of blowouts.
Are radial trailer tires better than bias-ply tires?
For most highway towing, yes. Radial trailer tires provide better heat dissipation, longer tread life, smoother towing, and improved fuel efficiency. Bias-ply tires are generally better suited for slower speeds or specialized off-road and agricultural applications.
Can I use passenger vehicle tires on my trailer?
No. Passenger tires are not designed to carry trailer loads and typically have softer sidewalls. For safety and performance, always use tires specifically designed for trailers unless your trailer manufacturer specifies otherwise.
How do I know what load range I need?
Your trailer’s fully loaded weight determines the required load range. Choose tires whose combined load capacity exceeds the maximum weight carried by the trailer’s axle or axles. Never exceed the tire’s rated load capacity.
What causes trailer tires to wear out quickly?
The most common causes include:
- Underinflated tires
- Overloading the trailer
- Excessive speed
- Poor wheel alignment
- Long-term sun exposure
- Infrequent maintenance
Regular inspections and maintaining the correct tire pressure can significantly extend tire life.
Final Recommendation
Your trailer tires are one of the most important investments you can make for safe, reliable towing. Whether you’re hauling landscaping equipment, construction materials, ATVs, a boat, or an RV, choosing the right trailer tire improves stability, reduces the risk of blowouts, and provides greater confidence on every trip. Selecting the proper tire size, load range, and construction for your trailer is just as important as routine maintenance and proper tire inflation.
If you’re looking for the best overall balance of performance, durability, and value, the Carlisle Radial Trail HD is our top recommendation. It offers dependable highway performance, excellent load-carrying capability, and long tread life, making it a great choice for most trailer owners.
