I noticed that the various compounds have different grip coefficients that manifest in the form of slip angle. With me driving the Callaway, for example, the softest compound has little to no drift when I'm driving to the limit, the slip angle is very small. In a fast turn, the car can be guided precisely with a balance of throttle, brake, and steering inputs. However, it takes me a while to find a set up that allows me this ability for I must accomplish two tasks. One, get the tires up to temperature. Two, don't overheat them. FFB and sound, when the tires are at optimal temperatures, help me figure out how to drive the car as fast as I can. Once I overheat them, however, the tires get "greasy" and it is readily palpable via the much lighter FFB and wandering steering wheel that does not seem to do much to guide the car. The slip angle seems to become gigantic. I find that I can drive the soft compounds like there's no tomorrow up until I make a mistake. They do not forgive me.
The medium compound is a good compromise. It is predictable and the drift/slip angle is very manageable. My driving style changes a bit with these tires. I have to be a bit smoother with the throttle and steering inputs. The brake pressure must be dropped substantially in order to avoid lock ups. I do find that these tires recover quicker from overheating than the softer compounds.
The hard compound tires I have not experimented with too much. I would rather not opine. I break these free very easily. So far, they've done nothing but frustrate me.
The rain compound works well. Where the soft compound tires find no grip the rain tires do. Once there's a racing line on the wet track it is possible to push quite a bit. For obvious reasons, these break free a bit more suddenly than the others but counter steering can save you from a spin.
