Tyre Selection

You can choose between four different types of tyre compound. There are two dry tyre compound, Soft and Wet. There are also two different wet weather compounds.
You should use 'Inters' for Damp conditions, and 'Wets' should be used for full wet conditions.
In the dry, typically, the softer tyre of a manufacturer will work faster over a single lap but lose performance quicker than the harder tyre.
