How to Choose the Right Trailer Tires for Your Needs?

When it comes to hauling heavy loads or towing your favorite recreational vehicle, the importance of choosing the right trailer tires cannot be overstated. Whether you’re towing a boat, camper, cargo, or utility trailer, the right tires can make a huge difference in safety, performance, and the longevity of your trailer.

With so many options available on the market, it’s easy to get overwhelmed. In this blog, we’ll break down the key factors to consider when selecting the right trailer tires for your specific needs—and help you find trailer tires for sale that match your requirements.

1. Understand the Different Types of Trailer Tires

Not all trailer tires are the same. The type of trailer you have will influence the kind of tire you need. The most common types include:

• ST (Special Trailer) Tires: These are designed specifically for trailers and provide a greater load-carrying capacity. They have thicker sidewalls and are made to handle the weight of the trailer and its cargo.

• P-Metric Tires: These are passenger vehicle tires, typically designed for cars. They are not recommended for trailers as they are not designed to handle the heavier load and stress.

• LT (Light Truck) Tires: These are intended for light trucks and offer a sturdier construction than P-metric tires. However, they don’t have the load-bearing capabilities of ST tires and are not optimal for trailers.

Which One to Choose?

• If you are towing a boat, RV, utility, or car hauler, ST tires are typically your best bet because they are specifically made for trailers.

• For lightweight utility trailers, some might choose LT tires for their added durability, but make sure to check weight ratings.

When shopping for trailer tires for sale, it's important to look for tires marked with ST for trailers. This ensures you're getting the correct type of tire for the job.

2. Consider the Load Rating

Every trailer tire comes with a load rating, indicating how much weight the tire can safely carry. This is crucial because overloading your tires can lead to blowouts, wear, and unsafe towing.

• Load Range: Trailer tires typically have a letter code that signifies their load range. The higher the letter, the higher the load capacity. For example, a Load Range C tire will handle less weight than a Load Range D tire.

• Weight of the Trailer and Cargo: Before purchasing, determine the Gross Trailer Weight (GTW) of your trailer, including its load. The tire’s load rating should meet or exceed this weight.

How to Check Load Ratings

Look for the Load Index printed on the sidewall of the tire. For example, if the tire reads “Load Range D,” this means it’s designed to handle a higher load than Load Range C. Make sure that your tires’ load rating matches or exceeds the combined weight of your trailer and cargo.

3. Choosing the Right Tire Size

Trailer tire sizes are marked with a combination of numbers and letters that provide valuable information. For example, you might see a tire size like ST205/75R15. Here’s what the numbers mean:

• ST: Special Trailer tire

• 205: The tire width in millimeters

• 75: The aspect ratio (height to width ratio)

• R: Radial construction

• 15: The tire’s diameter (in inches)

Make sure the tire size fits the rims of your trailer. You can find the appropriate tire size for your trailer in the owner’s manual or on the sidewall of your current tires.

Common Trailer Tire Sizes:

• ST175/80D13 – Typically used for smaller utility or utility-style trailers.

• ST205/75D14 – Common for boat trailers or light utility trailers.

• ST225/75D15 – Used for larger trailers, such as travel trailers or horse trailers.

When you’re on the hunt for trailer tires for sale, ensure you’re looking at tires that match your trailer’s specifications, including size and load rating.

4. Decide Between Radial vs. Bias Ply Tires

Trailer tires come in two primary types of construction: radial and bias ply. Each offers unique benefits, depending on how you plan to use your trailer.

• Radial Tires: These tires have cords that run perpendicular to the direction of travel. Radial tires generally offer a smoother ride, better fuel efficiency, and longer tread life. They are the most common choice for highway driving and long-distance hauling.

• Bias Ply Tires: Bias ply tires have cords that crisscross over each other at an angle. These tires tend to be more durable, provide more stability under heavy loads, and are often used for off-road trailers or those that carry extreme weight.

When to Choose Each?

• Radial tires are best for long-distance travel and highway use. They offer a better ride, greater fuel efficiency, and less heat buildup, which can prolong tire life.

• Bias ply tires are ideal for off-road use, carrying extremely heavy loads, or trailers that may see more rough terrain or varying road conditions.

When searching for trailer tires for sale, check the tire’s construction type (radial or bias ply) based on your intended use.

5. Think About Tread Pattern

The tread pattern of a tire influences its performance in different conditions, particularly when it comes to traction and handling.

• Highway Traction: If you're mainly driving on highways, a tire with a more shallow tread pattern will provide better fuel efficiency and a smoother ride.

• Off-Road Traction: For off-road use, look for tires with a deeper tread pattern designed to grip dirt, mud, or gravel.

Make sure to match the tire’s tread pattern to your typical driving conditions. If you plan to drive primarily on smooth, paved roads, go with a tire designed for road use. If you're taking your trailer off-road, an aggressive tread pattern will give you better grip.

6. Maintenance and Inflation

No matter how good your trailer tires are, regular maintenance is key to making sure they last as long as possible and perform well. Here are a few tips:

• Check tire pressure regularly: Under- or over-inflated tires can wear unevenly and may not provide optimal performance. Always follow the manufacturer’s recommended PSI, which you can find on the tire’s sidewall or in the trailer's owner’s manual.

• Inspect for Damage: Routinely check your tires for signs of wear, cracking, or bulges. Damaged tires should be replaced immediately to avoid dangerous driving conditions.

• Rotate Tires: If you’re regularly using your trailer, rotating the tires (if applicable) can help ensure even wear, prolonging their life.

7. Quality and Price

While it might be tempting to go for the cheapest option, it’s important to consider the quality of the tire. Tires are a critical part of ensuring the safety of your trailer, so investing in high-quality tires from reputable brands is always a good idea. In the long run, a quality tire may save you from costly repairs or dangerous situations.

Some trusted trailer tire brands include:

• Goodyear

• Michelin

• Carlisle

• Kenda

• Maxxis

Though these may be a bit more expensive, they often offer better durability and safety features. When browsing for trailer tires for sale, prioritize brand reputation and quality to ensure your safety on the road.

Conclusion

Choosing the right trailer tires is essential for the safety and longevity of your trailer. By considering factors like load rating, tire size, tire type, and the terrain you'll be driving on, you can ensure that your trailer is equipped with the best tires for your needs. Always prioritize quality and proper maintenance to keep your trailer running smoothly, no matter where your adventures take you.
