FIA  regulations on tyres

12.6 Specification of tyres :

12.6.1 An intermediate tyre is one which has been designed for use on a wet or damp track.

All intermediate tyres must, when new, have a contact area which does not exceed 280cm² when fitted to the front of the car and 440cm² when fitted to the rear. Contact areas will be measured over any square section of the tyre which is normal to and symmetrical about the tyre centre line and which measures 200mm x 200mm when fitted to the front of the car and 250mm x 250mm when fitted to the rear. For the purposes of establishing conformity, void areas which are less than 2.5mm in depth will be deemed to be contact areas.

12.6.2 A wet-weather tyre is one which has been designed for use on a wet track.

All wet-weather tyres must, when new, have a contact area which does not exceed 240cm² when fitted to the front of the car and 375cm² when fitted to the rear. Contact areas will be measured over any square section of the tyre which is normal to and symmetrical about the tyre centre line and which measures 200mm x 200mm when fitted to the front of the car and 250mm x 250mm when fitted to the rear. For the purposes of establishing conformity, void areas which are less than 5.0mm in depth will be deemed to be contact areas.

12.6.3 Tyre specifications will be determined by the FIA no later than 1 September of the previous season. Once determined in this way, the specification of the tyres will not be changed during the Championship season without the agreement of all competing teams.
