What is the tire size for a Rear Dump Trailer?

Jun 24, 2025

Hey there! As a supplier of Rear Dump Trailers, I often get asked about the tire size for these bad boys. So, I thought I'd take a few minutes to break it down for you.

First off, why does tire size matter? Well, it's all about performance and safety. The right tire size can ensure your trailer handles well, distributes weight evenly, and has the right amount of traction. On the flip side, the wrong tire size can lead to all sorts of problems, like poor handling, increased wear and tear, and even safety hazards.

Let's start with the basics. The tire size for a Rear Dump Trailer isn't a one - size - fits - all deal. It depends on several factors, such as the trailer's weight capacity, the type of terrain it'll be used on, and the load it'll be carrying.

Weight Capacity

The weight capacity of your Rear Dump Trailer is a major factor in determining the right tire size. If your trailer is designed to carry heavy loads, you'll need tires that can handle that weight. Generally, heavier trailers require larger and more robust tires. For example, a trailer with a high weight capacity of 30 tons or more might need tires in the 11R22.5 or 12R22.5 range. These tires are wider and have a stronger sidewall to support the heavy load.

On the other hand, if your trailer has a lower weight capacity, say around 10 - 15 tons, you could get away with smaller tires like 235/75R17.5. These tires are more compact and still provide sufficient support for lighter loads.

Terrain

The type of terrain your Rear Dump Trailer will be operating on also plays a crucial role. If you're mainly using your trailer on smooth highways, you can opt for tires with a smooth tread pattern. These tires offer less rolling resistance, which means better fuel efficiency. A common size for highway - use Rear Dump Trailers is 295/75R22.5.

However, if your trailer will be used on rough, off - road terrain, you'll need tires with a more aggressive tread pattern. Tires like the 11.00R20 with a deep, chunky tread are great for off - road use. They provide better traction on mud, gravel, and uneven surfaces, reducing the risk of getting stuck.

Load Type

The type of load your Rear Dump Trailer will be carrying can also influence tire size. If you're transporting loose materials like sand or gravel, the weight is distributed more evenly across the trailer. But if you're carrying large, bulky items, the weight distribution might be uneven. In the case of uneven weight distribution, you might need larger tires to ensure proper support and stability.

Now, let's talk about some common tire sizes you might come across when dealing with Rear Dump Trailers:

11R22.5

This is a very popular tire size for medium to heavy - duty Rear Dump Trailers. It offers a good balance between load - carrying capacity and durability. The "11" refers to the tire's width in inches, and the "22.5" is the diameter of the wheel in inches. These tires are often used in commercial applications where the trailer needs to carry significant loads over long distances.

235/75R17.5

These tires are smaller and are typically used on lighter Rear Dump Trailers. The "235" represents the tire's width in millimeters, the "75" is the aspect ratio (which indicates the height of the tire's sidewall as a percentage of its width), and the "17.5" is the wheel diameter in inches. They're a great choice for trailers that don't need to carry extremely heavy loads.

12R22.5

Similar to the 11R22.5, but with a slightly wider width. This extra width provides even more support for heavier loads. If your Rear Dump Trailer has a very high weight capacity, the 12R22.5 tires might be the way to go.
