What does "load index" represent on a tire?

The load index of a tire is a numerical code that indicates the maximum load a tire can carry when it is adequately inflated. Each load index corresponds to a specific maximum weight, allowing consumers to choose tires that are suitable for their vehicle's weight requirements. Understanding the load index is crucial for ensuring the tire can support the weight of the vehicle, passengers, and cargo without risk of tire failure.

This information is vital for safety, as using tires with an insufficient load index for a vehicle can lead to problems such as tire blowouts or reduced tire life. Moreover, the load index is separate from other tire specifications, like the type of vehicle suited for the tire, speed ratings, and temperature resistance, which focus on different performance and safety aspects. Thus, recognizing the significance of the load index helps in making informed tire choices for safe driving.
