Selecting the right tires is crucial for trailer safety and performance. The load range and ply rating are two key factors to consider when choosing tires.

What is Tire Load Range?

The load range of a tire refers to the maximum weight the tire can support at a specified air pressure. This rating is essential because it determines how much weight each tire on your trailer can handle. Choosing a tire with the correct load range for your Air-tow trailer is vital to prevent overloading, which can lead to premature wear, tire blowouts, and unsafe towing conditions.

Load ranges are usually represented by a letter, such as B, C, D, E, or F, with each subsequent letter indicating a higher load capacity. For example, a tire in load range C can handle less weight than a tire in load range D, even if they are the same size.

What Does Ply Rating Mean?

Historically, the ply rating of a tire referred to the number of layers (or plies) of cotton used in its construction. More plies meant a stronger tire that could handle higher loads. Today, tire technology has advanced, and the ply rating no longer directly relates to the number of layers in the tire. Instead, it indicates the tire’s strength and durability compared to older models.

 

For instance, a tire with a 10-ply rating doesn’t necessarily have ten plies. It means that the tire’s construction is equivalent in strength to a tire that used to be made with ten layers. This modern system provides a reliable way to compare tire durability and load-carrying capacity without getting too caught up in specific construction details.

Where to Find Ply Rating on the Tire?

The rating can be found on the sidewall of the tires. 

Air-tow’s Tire Quality and Range

At Air-tow, we equip our trailers with quality, highly desirable radial tread tires. These tires are known for their durability, smoother ride, and better traction than traditional bias-ply tires. All tires on Air-tow Trailers are specifically matched to carry the various trailer load ratings, ensuring you get the best performance for your specific model. Air-tow’s tire selection ranges from 8-ply to 16-ply. Whether transporting light equipment or heavy machinery, you can trust that Air-tow’s tires are built to provide reliable support.

How to Choose the Right Tire Load Range

Selecting the correct tire load range for your trailer involves considering your trailer’s maximum load capacity and the type of loads you’ll be hauling. Here are a few steps to guide you in making the right choice:

1. Check the Trailer’s Specifications: Refer to the owner’s manual or the data plate on your Air-tow trailer to determine the Gross Vehicle Weight Rating (GVWR). This number includes the trailer’s weight and maximum load capacity.

 

2. Match the Tire’s Load Range: Choose tires with a load range that meets or exceeds the trailer’s GVWR. This ensures that each tire can support its share of the weight without risking a blowout.

 

3. Consider Your Cargo: If you frequently haul heavy or unevenly distributed loads, opt for tires with a higher load range to add an extra layer of safety.

 

4. Don’t Forget Air Pressure: Your tires’ load-carrying capacity depends on maintaining the correct air pressure. Always follow the manufacturer’s guidelines for tire inflation to maximize performance and safety.

Practical Tips for Maintaining Tire Safety

Keeping your tires in top condition is as important as choosing the right type. Here are some essential maintenance tips to ensure a smooth and safe ride:

• Regular Inspections: Before each trip, check your tires for signs of wear, cuts, cracks, or uneven tread. Catching these issues early can prevent bigger problems on the road.

• Proper Inflation: Maintain the correct tire pressure according to the manufacturer’s recommendations. Under-inflated or over-inflated tires can lead to poor handling, reduced load capacity, and increased blowout risk.

• Rotate Your Tires: Regularly rotating your tires can help even out the wear and extend their lifespan, ensuring they last longer and perform more consistently.

• Replace Worn Tires Promptly: Don’t wait until the tread is completely gone to replace your tires. Worn-out tires reduce traction, compromising safety, especially in wet or slippery conditions.

The Bottom Line

Choosing the right tire load range and understanding ply ratings are essential steps in ensuring the safety and efficiency of your Air-tow trailer. By selecting the appropriate tires and keeping them well-maintained, you can help prevent accidents and enjoy a smoother, safer towing experience.If you’re replacing a tire and unsure which tires are best suited for your Air-tow trailer or have any questions about maintenance, feel free to contact our team.
