The Ultimate Guide to Choosing Tires for a Travel Trailer

Choosing the right tires for a travel trailer is one of the most important decisions you will make for your RV. These tires are the only thing connecting your home-on-wheels to the road. Therefore, ensuring they are safe, reliable, and appropriate for your trailer is essential for peace of mind on your adventures.

Unlike car tires, trailer tires are built for a different purpose. They need to handle heavy loads for long periods. Consequently, making an informed choice is not just about performance; it’s about safety.

Why Special Trailer (ST) Tires are Non-Negotiable

You might be tempted to use Light Truck (LT) tires, but this is a mistake. Special Trailer (ST) tires are specifically engineered for trailers. For instance, they have stiffer sidewalls to handle heavy vertical loads and reduce sway. Using the wrong type can lead to poor handling and dangerous blowouts.

Key Differences:

• Sidewall Strength: ST tires have reinforced sidewalls to manage the trailer’s weight without flexing excessively.
• Tread Compound: The rubber is designed for durability and long life, not for the traction needed for a drive axle.
• Load Capacity: They are built to carry their maximum rated load for extended durations. In addition, they are tested to meet specific industry standards for this purpose.

Key Factors to Consider When Buying Tires for a Travel Trailer

When you start shopping, the numbers and letters on a tire’s sidewall can be confusing. However, understanding them is key. Here’s what to look for:

• Tire Size: Always match the size recommended by your trailer’s manufacturer. You can find this information on the trailer’s placard or in the owner’s manual.
• Load Range: This indicates the tire’s carrying capacity. It’s represented by a letter (e.g., C, D, E). You must choose a load range that meets or exceeds the trailer’s Gross Vehicle Weight Rating (GVWR).
• Speed Rating: Most ST tires are rated for 65 mph (105 km/h). If you plan to drive faster, you must find a tire with a higher speed rating, like those rated ‘L’ (75 mph) or ‘M’ (81 mph).
• Manufacture Date: Tires degrade over time, even when not in use. Check the DOT code on the sidewall. The last four digits show the week and year it was made (e.g., ‘3524’ means the 35th week of 2024). Aim for tires less than a year old.

Top Recommended Brands for 2025

While specific models change, a few brands consistently deliver quality and reliability. We recommend looking into these options for your next purchase.

Goodyear Endurance

Goodyear is a trusted name for a reason. Their Endurance line is made in the USA and is known for its durability and higher speed rating (N, or 87 mph). As a result, it is a very popular choice among RV owners.

Carlisle Radial Trail HD

Carlisle offers a fantastic balance of performance and value. These tires are known for their robust construction and resistance to heat buildup, which helps prevent blowouts. They are a reliable workhorse for any travel trailer.

Maxxis M8008 ST Radial

Maxxis is another excellent brand that focuses on durability. The M8008 features an advanced tread compound that decreases rolling resistance. Subsequently, this can slightly improve your tow vehicle’s fuel economy.

Simple Maintenance Tips for Longevity

Buying good tires is only half the battle. Proper maintenance ensures they last as long as possible. Therefore, follow these simple steps:

• Check Air Pressure: Always inflate tires to the maximum PSI indicated on the sidewall when they are cold. Underinflation is a primary cause of tire failure.
• Inspect Regularly: Before every trip, look for cracks, bulges, or uneven wear.
• Cover Your Tires: When your trailer is parked for an extended period, use tire covers. This protects them from damaging UV rays.
• Don’t Overload: Respect your trailer’s GVWR. Overloading puts immense stress on your tires and can lead to catastrophic failure.

Ultimately, investing in high-quality tires for a travel trailer and maintaining them properly will protect your investment and, more importantly, keep you safe on the road.
