How is tire speed rating determined?
Tire manufacturers determine a tire’s capacity for heat and speed using a testing machine. Starting at a speed 40 km/h lower than the proposed rating level, the tire is spun for 10-minute increments at higher and higher speeds, until it reaches the target speed. The tire spins for 10 minutes at the target speed.
