What does the service description on a tire indicate?

The service description on a tire is essential because it provides critical information about the tire's performance capabilities. Specifically, it indicates the load index and the speed symbol. The load index represents the maximum weight a tire can safely support when properly inflated, while the speed symbol denotes the maximum speed at which the tire can operate under its rated load capacity without overheating. This information is crucial for ensuring that the tire is suitable for the vehicle it is installed on and that it meets safety and performance requirements. Understanding the service description helps in selecting the right tire for specific driving conditions and vehicle specifications, ultimately enhancing safety and performance.
