What does the ply rating refer to in tire specifications?

The ply rating in tire specifications indicates the tire's maximum intended load, which relates to the tire's ability to carry weight under various conditions. This rating is a measure of the tire's strength and durability, referencing how much weight the tire can support safely. Typically, a higher ply rating translates to a stronger tire that can handle heavier loads, making it crucial for performance and safety, particularly in vehicles that require robust tire support due to their weight or usage.

While other factors such as inflation pressure and tread patterns are important for overall tire performance, the ply rating specifically focuses on load capacity. Understanding this distinction is vital for selecting the appropriate tire for different types of vehicles and applications.
