Load Rating: Maximum Weight Capacity Explained

The load index is a numerical code representing the maximum weight in kgs that a single tyre can safely carry. To ensure safety, the combined capacity of all four tyres must exceed the vehicle’s total weight when fully loaded.

Speed Rating: Maximum Velocity Explained

Represented by a letter, the speed rating indicates the maximum kph a tyre can maintain over a prolonged period. Higher speed ratings are engineered to handle the heat and stresses generated at faster speeds more effectively.
