What Are ST Tires and Why They Matter
One of the first things you’ll notice when shopping for trailer tires is the designation “ST”, which stands for Special Trailer.
What Makes ST Tires Different?
ST tires are specifically engineered for trailers, unlike passenger (P) or light truck (LT) tires. They are designed to handle:
- Heavier loads
- Higher inflation pressures
- Increased sidewall stiffness for stability
- Reduced sway during towing
Why You Should Always Choose ST Tires
Using the correct tire type is critical. Here’s why ST tires are the preferred choice:
- Enhanced Load Capacity: Built to carry heavier loads than passenger tires.
- Improved Stability: Reinforced sidewalls reduce trailer sway.
- Durability: Designed for long-distance towing and harsh road conditions.
If you’re searching for trailer tires for sale, always prioritize ST-rated options to ensure safety and compliance with manufacturer recommendations.

Choosing the Right Trailer Tire Size
Selecting the correct tire size is essential for performance and safety. Trailer tire sizes may look confusing at first, but they follow a standard format.
How to Read Trailer Tire Sizes
Example: ST205/75R15
- ST – Special Trailer
- 205 – Tire width in millimeters
- 75 – Aspect ratio (height as a percentage of width)
- R – Radial construction
- 15 – Wheel diameter in inches
Tips for Choosing the Correct Size
- Check your trailer’s manual or placard for manufacturer recommendations.
- Match the existing tire size unless upgrading for a specific purpose.
- Ensure proper clearance in the wheel well if changing size.
Switching to the wrong size can lead to uneven wear, reduced load capacity, and even tire failure.

Understanding Load Range Trailer Tires (C, D, E)
One of the most important factors when choosing RV trailer tires or boat trailer tires is the load range.

Load range indicates how much weight a tire can safely carry at a specified air pressure.
Common Load Ranges Explained
Load Range C

- Best for: Light-duty trailers
- Use Case: Small utility trailers, lightweight campers
Load Range D
- Typical PSI: ~65 psi
- Best for: Medium-duty applications
- Use Case: Travel trailers, mid-size cargo trailers
Load Range E

How to Choose the Right Load Range
