Load & Speed
The symbol that shows a tires performance level consists of two parts: Tire performance is marked by load index (LI) and speed symbol (SS). LI refers to the maximum weight that one tire can support and SS refers to the maximum speed that a tire can handle.
Speed symbol indicates the maximum speed at which the weight (with the exception of weight when speed
is equal to or exceeds 210 km/h), designated by the manufacturing company can be supported by the tire.
