Tire Speed Index

    It is the expected maximum speed capacity expected from the tire at maximum load the tire will carry. A tires speed symbol, forms one part of load index and is a letter showing maximum speed suited to tires load index to be carried by the tire. (K stamp should not exceed 110 km per hour, Q stamp 160 km per hour and H stamp not to exceed 210 km per hour). Only minimum speed proportioned tires Indicated on the vehicles operation manual can be used on the vehicle.

Tire Load Index

The load proportion of the tire is a numerical value of the maximum load a tire can carry specified in a speed of certain air pressure and speed symbol. At the below table you can find the proper maximum weight in kilogram (kg).
