What type of tire markings are specific to light trucks?

The markings that are specific to light trucks include the Max. Load Dual and Single information. This is significant because light truck tires are designed to carry heavier loads than regular passenger vehicle tires. As a result, understanding the maximum load a tire can safely carry is essential for safety and proper vehicle operation.

The Max. Load markings indicate the highest weight the tire can support either when in a dual configuration (used on the same axle) or a single configuration (used individually). This information helps ensure that the vehicle is not overloaded, which can lead to tire failure and compromise vehicle safety.

Other markings such as load index, speed ratings, and traction and temperature grades provide important information about the tire's performance and capabilities but are not unique to light trucks. They apply to various types of tires and do not specify the unique load capacities necessary for light truck applications. This highlights the necessity of Max. Load Dual and Single information as critical for tire safety in light trucks.
