Load & Speed

The symbol that shows a tyres performance level consists of two parts: Tyre performance is marked by load index(LI) and speed symbol(SS). LI refers to the maximum weight that one tyre can support and SS refers to the maximum speed that a tyre can handle.

  • Load Index(LI)
    • Load index is a numerical code stipulating the maximum load each tyre can carry.
      For example, if the load index is 100, it means that a tyre can carry a load up to 800kg.

    • How much weight can your tyres support?
      Enter your tyres load Index in the boxes below and press ‘Enter’.

  • Speed Symbol(SS)
    • Speed Symbol indicates the maximum speed at which the weight (with the exception of weight when speed is equal to or exceeds 210km/h) designated by the manufacturing company can be supported by the tyre.
