Hard and soft tires
Bridgestone will be providing teams with dry tires, with “soft” and “hard” designations to the twelve teams participating in the South Korean Formula 1 Grand Prix.
The softest rubber tires the one called “soft”, will be identifiable, as regulated by the International Automobile Federation (FIA), with a green mark on the car tires.
Brdigestone has delivered four types of tires for dry racing conditions this season. These are called hard, ‘medium’, soft and extra soft. But only two of these four types of tires are chosen to be used at each of the Grand Prix races.
