In the tyre designation "315/80 R 22.5 156/150 L," the letter "L" denotes the maximum permissible speed for the tyre. In this case, it indicates a speed rating. The numbers "156/150" refer to the load index, which specifies the load-bearing capacity of the tyre when properly inflated.

For comprehensive understanding, it's crucial to recognize that both the speed rating and load index work together to assure the safety and performance of the tyre. The speed rating ensures the tyre can handle the intended maximum speed without risk of failure, while the load index provides information on how much weight the tyre can safely support. In German traffic laws, adhering to these specifications is vital for vehicle safety and compliance.
