Tire stiffness and speed
Softer tires provide better traction and therefore enable a go-kart to complete laps around a go-kart circuit in a shorter time, than hard tires.
This experiment was conducted to ascertain the relationship between the stiffness or hardness of a tire and the speed that can be achieved by a racing car. Three types of tires of different stiffness/hardness are tested using go-kart vehicles.
Soft tires -these are tires made of relatively softer rubber. These tires provide very good traction but they wear out very quickly. Another disadvantage of soft tires is they are very expensive.
Medium tires -these tires fall between the soft tires and hard tires. They offer better traction than hard tires but are not as good as soft tires in terms of speed performance. They also last longer than soft tires.
Hard tires -these tires provide poor traction and therefore produce a slower speed, but are able to last longer.
