Why the Right 13 Inch Tire Makes All the Difference

You’ve invested in a motorcycle trailer to safely transport your bike—whether it’s a Harley, a sportbike, or a vintage classic. But have you given enough thought to the tires carrying that precious cargo? Many riders overlook trailer tires, assuming any old rubber will do. That’s a risky mistake. The best 13 inch tire for a motorcycle trailer isn’t just about size—it’s about performance, durability, and peace of mind.

Trailer tires face unique challenges. They’re often underinflated, overloaded, or left sitting for months. Unlike car tires, they don’t benefit from regular rotation or alignment checks. And when they fail—whether through blowouts, tread separation, or sidewall cracks—the consequences can be dangerous. A blown tire on a trailer can cause swaying, loss of control, or even a crash. That’s why choosing a high-quality 13 inch tire designed specifically for trailer use is essential.

In this guide, we’ll walk you through everything you need to know to pick the perfect tire. From understanding load ratings and construction types to comparing top brands and learning maintenance tips, we’ve got you covered. Whether you’re hauling your bike across the country or just to the local track day, the right tire ensures a smooth, safe journey.

Understanding 13 Inch Trailer Tires: What You Need to Know

Before diving into specific models, it’s important to understand what makes a 13 inch tire suitable for a motorcycle trailer. These tires are typically used on small to medium-sized trailers—think single or dual motorcycle haulers, utility trailers, or even small cargo trailers. They’re compact, lightweight, and designed to handle moderate loads efficiently.

Size and Fit Basics

The “13 inch” refers to the wheel diameter, not the overall tire height. A common size you’ll see is ST175/80D13 or ST175/80R13. Let’s break that down:

• ST: Stands for “Special Trailer”—these tires are built specifically for trailer use, with stiffer sidewalls and higher load capacities than passenger tires.
• 175: The tire width in millimeters (about 6.9 inches).
• 80: The aspect ratio—the sidewall height is 80% of the width.
• D or R: “D” means bias ply construction; “R” means radial. Radial tires are generally preferred for their smoother ride and better heat resistance.
• 13: The wheel diameter in inches.

Always check your trailer’s manual or existing tire sidewall to confirm the correct size. Using the wrong size can affect handling, braking, and safety.

Load Range and Ply Rating

Trailer tires are rated by “load range,” which corresponds to their maximum load capacity and required inflation pressure. Common load ranges for 13 inch tires include:

• Load Range B: 4-ply rating, max load around 1,220 lbs at 35 psi.
• Load Range C: 6-ply rating, max load around 1,650 lbs at 50 psi.
• Load Range D: 8-ply rating, max load around 2,040 lbs at 65 psi.

For a single motorcycle trailer, Load Range C is usually sufficient. But if you’re hauling two heavy bikes or adding gear, consider Load Range D for extra safety margin.

Radial vs. Bias Ply: Which Is Better?

This is one of the most common questions. Here’s the breakdown:

Radial tires have steel belts running radially across the tread, allowing the sidewall and tread to flex independently. This results in:

• Better heat dissipation (less risk of blowouts).
• Longer tread life.
• Smoother ride and better fuel efficiency.

Bias ply tires have crisscrossed fabric layers, creating a stiffer, more durable structure. They’re better for:

• Heavy loads and rough terrain.
• Trailers that sit for long periods (less prone to flat-spotting).

For most motorcycle trailers used on paved roads, radial tires are the better choice. But if you frequently tow off-road or carry extremely heavy loads, bias ply might be worth considering.

How to Choose the Right Tire for Your Trailer

With so many options, how do you pick the best one? Start by answering these key questions:

What’s Your Trailer’s Weight?

Add up the weight of your motorcycle(s), gear, and the trailer itself. Then check the tire’s load rating. Always choose a tire with a capacity at least 20% higher than your max load for safety.

Example: If your fully loaded trailer weighs 1,400 lbs, go with a Load Range C tire (1,650 lbs capacity) or higher.

How Often Do You Tow?

Frequent towing? Go radial for longevity and comfort. Occasional use? Bias ply might be fine, but consider a radial anyway for better heat management.

Where Do You Tow?

Highways and paved roads? Ribbed radial tires are ideal. Gravel, dirt, or wet conditions? Look for deeper tread or consider bias ply for added sidewall strength.

Do You Store Your Trailer?

If your site sits for months, invest in tire covers and check pressure regularly. Radial tires are less prone to flat-spotting, but all tires degrade over time—even when not in use.

Budget Considerations

Don’t just go for the cheapest option. A $60 tire might save you money upfront but cost more in the long run due to shorter life or higher failure risk. Aim for the best value—quality at a fair price.

Installation, Maintenance, and Safety Tips

Even the best tire won’t perform well if it’s not installed or maintained properly. Follow these tips to get the most out of your investment.

Proper Installation

Always have tires installed by a professional or someone experienced with trailer wheels. Improper mounting can lead to imbalance, vibration, or failure. Use a torque wrench to tighten lug nuts to the manufacturer’s specs (usually 90–120 ft-lbs).

Inflation Is Critical

Underinflation is the #1 cause of trailer tire failure. Check pressure before every trip, when tires are cold. Use a quality gauge and inflate to the psi listed on the tire sidewall—not the max pressure, but the recommended load-based pressure.

Tip: Keep a portable air compressor in your vehicle for on-the-go adjustments.

Regular Inspections

Look for:

• Cracks or dry rot on the sidewall.
• Bulges or blisters (signs of internal damage).
• Uneven tread wear (could indicate alignment or suspension issues).
• Embedded nails or debris.

Inspect tires monthly, even if you’re not towing.

Storage Tips

If storing your trailer for more than a month:

• Inflate tires to recommended pressure.
• Use tire covers to protect from UV rays.
• Elevate the trailer slightly or move it occasionally to prevent flat spots.

Always Carry a Spare

A matching spare tire is non-negotiable. Make sure it’s the same size, load range, and type (radial or bias) as your other tires. Store it securely and check its condition regularly.

Common Mistakes to Avoid

Even experienced riders make these errors. Avoid them to stay safe and save money.

Using Passenger Car Tires

Never use car tires on a trailer. They’re not built for the constant load and lack the reinforced sidewalls of ST tires. The result? Blowouts and dangerous sway.

Ignoring Age

Tires degrade over time, even if they look fine. Most manufacturers recommend replacing trailer tires every 5–7 years, regardless of tread depth. Check the DOT code on the sidewall to find the manufacture date.

Overloading

Exceeding your trailer’s weight limit puts immense stress on tires. It can cause overheating, tread separation, or sudden failure. Know your limits.

Mixing Tire Types

Never mix radial and bias ply tires on the same axle. They behave differently under load and can cause handling issues.

Conclusion: Invest in Safety and Peace of Mind

Choosing the best 13 inch tire for a motorcycle trailer isn’t just about replacing worn rubber—it’s about protecting your bike, your vehicle, and yourself. The right tire ensures stable towing, reduces the risk of breakdowns, and gives you confidence on every mile.

From the reliable Carlisle Radial Trail HD to the heavy-duty Goodyear Endurance, there’s a tire for every need and budget. Focus on load capacity, construction type, and real-world performance. And don’t forget maintenance—regular checks and proper inflation can double a tire’s life.

Your motorcycle deserves the best care, even when it’s not on the road. With the right trailer tire, you’ll enjoy smoother rides, fewer worries, and more time doing what you love: riding.

Frequently Asked Questions

Can I use a car tire on my motorcycle trailer?

No, car tires are not designed for trailer use. They lack the reinforced sidewalls and load capacity of ST (Special Trailer) tires, increasing the risk of blowouts and sway.

How often should I replace my trailer tires?

Even with good tread, replace trailer tires every 5–7 years. Rubber degrades over time, and aging tires are more prone to cracking and failure.

What’s the difference between ST and LT tires?

ST tires are made for trailers, with stiffer sidewalls and higher load ratings. LT (Light Truck) tires are for vehicles and not ideal for trailer use.

Do I need to balance trailer tires?

Yes, balancing reduces vibration and uneven wear. Have them balanced when installed, especially if you notice shaking at highway speeds.

Can I tow with a spare tire long-term?

No, spare tires are for emergencies only. They’re often smaller or have different specs, which can affect handling and safety.

Why do my trailer tires wear unevenly?

Uneven wear can signal alignment issues, overloading, or suspension problems. Have your trailer inspected by a professional if you notice irregular tread patterns.
