Tire temperatures and brakes?

[nacho]

Every year, no matter which tires are used, there is always a lot of talk about tire temperatures.

How big a role does the heat dissipated by the brakes have in tire temperatures? Do the cars have some systems to adjust the amount of heat transferred from the brakes to the tires?

As in active systems? I don't think so, but the 'drums' around the entire brake system were introduced for this very reason.

Ok I see, but shouldn't it be possible to modify that to bring up the tire temperatures?

Oh I see, you mean to use the brake system heat for the tyres. I don't think it would be a good idea during a race though, where tyre wear over a long distance is crucial. Perhaps for qualifying running a drum that doesn't cover the entire system could be possible. Other things to consider are the weather and circuit.

Never mind the qualy comment; parc ferme.

Yes that is what I meant, to transfer the heat from brakes to tires.
