what does load range d mean on trailer tires

When selecting trailer tires, one of the most important things to consider is load range. Understanding what load range means can help you choose the right tire for your trailer and ensure safe travels. Load range D is a commonly used term in the world of trailer tires, and it's important to know what it means.

What is Load Range D?

Load range D refers to the weight capacity of a tire and indicates how much weight the tire can safely carry at a specified PSI (pounds per square inch) of air pressure. The load range letter is typically found on the sidewall of the tire, along with other information such as the tire size and maximum PSI.

Load Capacity of Load Range D

The load capacity of load range D tires depends on the size of the tire. For example, a load range D tire with a size of ST225/75R15 has a maximum carrying capacity of 2,540 pounds at 65 PSI. On the other hand, a load range D tire with a size of ST205/75R14 has a maximum carrying capacity of 2,040 pounds at 65 PSI. It's important to note that exceeding the maximum weight capacity can result in tire failure, which can be dangerous.

When to Use Load Range D Tires

Load range D tires are ideal for trailers that carry heavy loads, such as livestock trailers, boat trailers, and utility trailers. Using tires with a lower load range can result in premature tire wear and can be dangerous if the weight capacity is exceeded. Load range D tires are designed to withstand the weight of heavier trailers and provide optimal handling and stability.

Conclusion

Load range D is a crucial factor to consider when selecting trailer tires. Understanding what load range means and knowing the load capacity of your tires can ensure safe travels and prevent tire failure. When using heavy trailers, it's important to use load range D tires that can handle the weight capacity, providing optimal handling and stability.
